1 Embedded SDK 3.0 Release Notes This version is recommended for use with Metrowerks CodeWarrior 5.1. The following changes were made to the SDK to make it work with CodeWarrior 5.1: - All SDK projects (*.mcp) were converted to use CodeWarrior F801FA60 and 56F802FA60 Support: - New Stationery for 60MHz parts (dsp56f800_demoboard) - Software libraries and peripheral drivers (BSP) supported by current DSP56F801EVM installation directory. Some modules may not work at 60MHz. - Demo Applications located in \sdk\src\dsp56f800_demoboard\nos folder. See the document titled, Targeting Motorola 56F800 Demonstration Board for further details on these applications: Frequency Detector Frequency Spectrum POT Controlled LEDs Quad Timer Serial Boot Loader Timers New Telephony Algorithms: (Documentation included and software available upon request) - G168 (56F803x, 56F82x) - Common Tone Generator (56F80x, 56F82x) - MFCR2 (56F80x, 56F82x) New Modem Algorithms: - v.21 (56F803/805/807, 56F82x) New BSP Drivers: - TDC1 DAA/Codec (56F827) supports new telephony daughter card Corrected 56F801 Stationery to use path names based on Embedded SDK source environment variable. None Previous Releases Embedded SDK 2.5 Release Notes This version is recommended for use with Metrowerks CodeWarrior 5.0. The following changes were made to the SDK in order to make it work with CodeWarrior 5.0: - All.mcp projects within the SDK were converted to use CodeWarrior The CW V1 5.0 inline assembler enforces the syntax that requires a # to precede immediate values. The instances in the SDK that previously specified immediate values without the # were changed to include it. - The SDK uses some macros with parameters that are intended to pass immediate values. These macros were changed to precede these parameters with #. The method for doing this is not straight forward. It requires a symbol be defined as # and this symbol then be used inside the macro definitions. For example:

2 #define IMMED # #define bitset(mask, Addr) asm(bfset IMMED Mask,Addr) - The CW V1 5.0 inline assembler has been upgraded to flag pipeline dependencies and insert NOPs as required. The instances in the SDK where warnings were issued for this were modified by adding NOP instructions to eliminate the warnings and to make it obvious where it might be possible to reorder the code to eliminate the NOPs to optimize the code. - Some linker command files had to be modified by adding.bss sections for memory now specified by the compiler for un-initialized data. Previously the compiler specified.data sections for all data memory. - Some bug fixes in the CW V1 5.0 resulted in an increase in code size in some cases. This resulted in the testrfft.mcp project code size increasing to the point where it overflowed the available memory. This was handled by dividing this project into two smaller projects, one that contains the Assembly testing and the other that contains the C code testing. Customers may run into similar problems if the size of their applications are close to the available memory. DSP56F802 support: New Stationery Updated Targeting DSP5680x Manual to include method to convert DSP56F801 applications to DSP56F802. Created new 801/802 serial bootloader to run from internal oscillator Created calibration routine to trim internal oscillator to 8MHz for 801/802 DSP56F801 support: Created function to calibrate internal oscillator to take advantage of 8MHz calibrated internal oscillator for all 801 parts with a date code greater than 0152 marked in the lower right corner of the part. New motor control Application and Library: 3ph_srm_ encoder Switched Reluctance Library Added Flash Programming support via PC parallel port. See new program in the x86/win32/applications directory called flash_jtag_loader The V.22bis Library was enhanced to report Loss of Carrier when in Data mo de. See the V.22bis Library documentation for details. Multichannel support for the following algorithms: CallerID, g165, g711, 3DES, DES, RSA PC master software: see updated documentation for list of changes Unified serial boot loader applications across all Flash targets. See version history below for detailed list of changes and targets supported by each version released. Version History: Display Description Nothing First release version did not display a version number This version operates at 19.2 kbps and displayed a progress bar. 1.1 Optimized for speed so it would run at kbps. Had to remove the progress bar to achieve higher rate. Supports 80x and Added support for 827 and additional error checking for overwriting the flash section containing the bootloader code. 1.3 Modified 801 to calibrate internal oscillator. It expects the calibration value to be stored in the information block of the Data Flash at address 0x103F. Unified bootloaders through conditional compiles to support 80x, 826, and 827.

3 Miscellaneous bugs fixed: bit.h corrected implementation of bitwordclear for all 80x/82x targets DSP56F827 Target: SIM driver has SCI and SPI select corrected. This register has this functionality swapped from the DSP56F826. DSP56F826/DSP56F827 has new TOD application and documentation. Allowing override of preprocessor definitions for COP variables on all platforms. Fixed decioctl DEC_SET_CALLBACK_INDEX command. Several problems with the SPI driver were fixed. Embedded SDK Release Notes This version is recommended for use with Metrowerks CodeWarrior 4.0 and patch. The patch can be accessed on the SDK CD or at this URL: This patch allows the customer to specify the values for the Flash programming timeout registers. New ADC driver for the DSP56F827 target. New Serial bootloader for DSP568F27 target. MSCAN Driver configuration table moved to data flash Implemented assembler version of the MSCAN driver receive ISR handler with better timing Motor Control: Following Motor Control Applications are now provided in the standard Embedded SDK for DSP56800: - 3 Phase AC Induction Motor Vector Control - 3 Phase Permanent Magnet Motor Vector Control - 3 Phase Switched Reluctance Motor Sensorless Control Miscellaneous bugs fixed: - DSP56F827 Target: qtimerdrv.c QTISR did not save and restore a register - DSP56F801/803/805/807 Targets: timerdrv.c Fixed problem with tv_nsec rolling over valid range of 999,999, MSCAN now compiles under all configurations with Relaxed pointer types option disabled. Documentation Issues: Targeting Motorola DSP5680x Platform corrections: Chapters affected: - DSP56F803 Applications: To load the 3 Phase ACIM Vector Control application into the DSP56F803 EVM board, remove jumper JG2, Enable on-board Parallel JTAG Command Converter Interface. - DSP56F805 Applications: To load the 3 Phase ACIM Vector Control application into the DSP56F805 EVM board, remove jumper JG5, Enable on-board Parallel JTAG Command Converter Interface. - DSP56F807 Applications: To load the 3 Phase ACIM Vector Control application into the DSP56F807 EVM board, remove jumper JG4, Enable on-board Parallel JTAG Host/Target Interface.

4 Embedded SDK 2.4 Release Notes This version is recommended for use with Metrowerks CodeWarrior 4.0 and patch. The patch can be accessed on the SDK CD or at this URL: This patch allows the customer to specify the values for the Flash programming timeout registers. COP driver for the DSP56F80x, DSP56F826, and DSP56F827 targets. Motor Control: - 3 Phase AC Induction Motor Vector Control - 3 Phase Permanent Magnet Motor Vector Control - 3 Phase Switched Reluctance Motor Sensorless Control Added Voice Recognition library that includes VRLite-1 algorithm. DSP56F827 Target: - BSP Library: Button, Codec, FileIO, Flash, GPIO, IPR, ITCN, LED, Programmable Chip Select, PLL, Quad Timer, SCI, SPI, Serial Data Flash, SIM, Time Of Day, PC Master - DSP Function Library - Modem Library: V.22bis, V.42bis, V.8bis - Security Library: DES, 3DES, RSA - Speech: Voice Recognition (VRLite-1) - Telephony Library: Acoustic Echo Cancellation, Caller ID, CAS detection, Call Progress Tone Detection, DTMF Detection and Generation, G165, G711, G726, Voice Activity Detection New EVM Hardware User Manual for DSP56F827 New Motor Control Application notes (see SDK Help for details). SCI driver added a new ioctl command GET_READ_SIZE. This command returns number of bytes or words that are ready to be read in the Receive buffer by the next read() call. The DSP function library has been updated to provide Create and Init interfaces for all library functions. Updated DSP56F826/ Bit Digital Signal Processor User s Manual that includes 827 documentation. Updated code examples for SDK Targeting manuals and Programmer s Guide. DTMF Generation library allows multiple instances. Miscellaneous bugs fixed: - Implement timer delete function. - Increase precision of clock_gettime(). - Quad Timer compile problem: the QT_FAST_RESTART function does not compile correctly. - There is a bug in the "config.c" file that will not allow the timer's "One Shot" mode to be selected, and the additional bits that need to be set or cleared are not handled properly. There were also problems with the "Pulse Output", "Fixed Frequency PWM", and "Variable Frequency PWM" modes. The "One Shot" mode is required to use the PWM to trigger the ADC. - The default value in SDK is 1, but that is not a legal value based on the performance capabilities of the ADC. The minimum useful divisor value is 3. I recommend you set the default value to 3. - I found a bug in the Motorola SDK, in the interrupt33.asm file. This is the ISR for the Timer C Channel 3 interrupt. - Enabled type checking on pointers for the DSP56F803 target. Remaining targets to be completed in future releases. Stationery changed to disallow the Relaxed Pointer Type Rules option as well. Corrected API documentation. No driver support for Analog to Digital Converter on the DSP56F827. Motor control test cases have been removed from default installation due to an installation problem on Windows 98 machines. If these elements are required, they may be successfully installed by shortening

5 the default installation path. For example, change default: C:\Program Files\Motorola\Embedded SDK to C:\SDK. The DTMF generation demo for the DSP56F824 operates intermittently. The SCI driver will not work when configured with SCI_BAUD_ baud rate. If including the DSP Function Library and performing floating point calculations, it is necessary to turn off saturation mode to get the correct floating point results. Example Code: #include "port.h" #include "arch.h" void main (void) { bool bsatmode; float x=4.6, y=2.3, z; bsatmode = archgetsetsaturationmode(false); z = x/y; } archgetsetsaturationmode(bsatmode); The Narrow Band Filter application for DSP56824 and DSP56F826 target is provided as a reference only. It does not have the supporting applications to execute. Embedded SDK Release Notes This version is recommended for use with Metrowerks CodeWarrior 4.0 and patch. The patch can be accessed on the SDK CD or at this URL: The following functions have been added to the DSP Function Library: void dfr16cfftinit (dfr16_tcfftstruct * pcfft, const int size, UInt16 options); void dfr16cifftinit (dfr16_tcfftstruct * pcfft, const int size, UInt16 options); void dfr16rfftinit (dfr16_trfftstruct * prfft, const int size, UInt16 options); void dfr16rifftinit (dfr16_trfftstruct * prfft, const int size, UInt16 options); These FFT Init functions initialize the FFT data structure, passed into the function as the first parameter, which has been preallocated by the caller. These FFT Init functions offer an alternative to the FFT Create functions which dynamically allocate and then return the FFT data structure. If you use the FFT Init functions, do not use the FFT Create/Destroy functions. These functions are not yet documented in the Embedded SDK DSP Function Library specification. The Memory Management Services memmalloc and memfree routines now cause a link error on the symbol memnumempartitions if used within an application without a #define INCLUDE_MEMORY in the appconfig.h file or without the memory management partition data structure defined in the linker.cmd file. This type of error is typically caused by the application erroneously calling a..create function without specifying #define INCLUDE_MEMORY in appconfig.h or without defining a dynamic memory management partition data structure in linker.cmd. The standard SDK linker.cmd file for Flash intentionally does not define a dynamic memory management partition, under the assumption that few real-time embedded applications will use dynamic memory in production. Therefore, if you get the unresolved symbol memnumempartitions in a link for a Flash application, please use the appropriate DSP Function Library..Init functions

6 rather than..create /..Destroy. DSP56F801 Target: - Serial Boot Loader - Brushless DC Motor application using ADC sensorless control DSP56F826 Target: - Serial Boot Loader - Time Of Day driver - Updated Codec Driver - Serial Data Flash driver replaced EEPROM driver previously on alpha EVM boards - Telephony Library: Acoustic Echo Cancellation, Caller ID, CAS detection, DTMF Detection and Generation, G165, G711, G726, Voice Activity Detection - Security Library: DES, 3DES, RSA - Modem Library: V.22bis, V.42bis, V.8bis New EVM Hardware User Manuals for DSP56F801 and DSP56F826 The dfr16rfft function in the DSP Function Library has been modified to execute correctly from Flash. Previous versions could fail to work correctly when executed from Flash. SDK Documentation has been updated to provide better on-line help that includes index, search, and bookmark capabilities for easier access to key SDK topics. New DSP56F826/ Bit Digital Signal Processor User s Manual Serial Boot Loader improved to communicate at bps and program flash at an effective rate of 7660 characters per second or 1740 words per second compared to the previous rate of 1450 characters per second or 330 words per second. If including the DSP Function Library and performing floating point calculations, it is necessary to turn off saturation mode to get the correct floating point results. Example Code: #include "port.h" #include "arch.h" void main (void) { bool bsatmode; float x=4.6, y=2.3, z; bsatmode = archgetsetsaturationmode(false); z = x/y; } archgetsetsaturationmode(bsatmode); The Narrow Band Filter application for DSP56824 and DSP56F826 target is provided as a reference only. Embedded SDK 2.3 Release Notes This version is recommended for use with Metrowerks CodeWarrior 4.0 and patch. The patch can be accessed at URL:

7 SDK documentation has been upgraded to better explain the SDKs purpose, design, and utilization of its functions. This improvement is reflected in the online help and source code headers and comments. New platforms supported: DSP56F801, DSP56F807, DSP56F826 Access to the lower layer interfaces is now possible for most BSP elements. New Algorithms and Applications: Security: Triple DES* Telephony: Call Progress Tone Detection Voice Activity Detection* CAS Detection Acoustic Echo Canceller* Modem: V.8bis V.42bis Error Correction/ Data Compression* Motor Control: Applications: AC Induction Motors (ACIM) V/Hz Open Loop with Power Factor Correction Brushless DC Motors w/ Encoder Sensorless Brushless DC Motors w/ Back-EMF ADC Synchronous Permanent Magnet Closed Loop with Encoder Digital Power Factor Correction (stand alone) Algorithms : BLDC Commutation Sensorless - Back-EMF Measurement (* - documentation included and software available on request) Provided a mechanism for placing constant variables in Data Flash (See new linker.cmd). Provided mechanism for removing "assertions" from code (See comments in assert.h). Added serial boot loader application that is target system independent. This application is also delivered in the Boot Flash of the XC qualified DSP56F80x family parts. Improved Embedded SDK Stationery. The new Stationery contains a modified linker.cmd file to provide more optimal placement of code and data segments. The Dependencies folder has also been restructured to make it more understandable. The following steps are required to update your previous Metrowerks Embedded SDK Stationery projects to the SDK 2.3 Metrowerks Embedded SDK Stationery compliant projects. - Create a new project by using the new Embedded SDK Stationery. - This will automatically include all the files required as well as including the new SDK 2.3 Linker.cmd file. - Delete main.c, and SampleAsm.asm from the Metrowerks project and from your project folder on your disk drive. - Move all source files ( C and Assembly) from the old project folder to the new project folder on your disk drive. - Move current application configuration file(s), appconfig.h, to the new project folder ( \project\configxx) on your disk drive. - Add the appconfig.h, C source code, and ASM files in to the new Metrowerks project. - Add all SDK libraries required by the previous project to the new Metrowerks project. - The conversion is now complete and the project may be compiled to take advantage of the SDK 2.3 upgrades. The DTMF detection algorithm has been upgraded to detect DTMF tones in the presence of speech. The G165 algorithm has added a control feature for re-enabling convergence. API changes have been made to improve interfaces: The API for requesting the input frequency to the quadrature timer is now returned in a variable allocated in the application code and passed in the following function call:

8 ioctl(qtimerfd, QT_GET_INPUT_CLK_FREQ, &QtInputFrequency). (See the Targeting Motorola DSP5680x Platform, Chapter 5.5 Quadrature Timer Driver for more information on the new API.) This information was previously returned in the inputfreq variable of the qt_sstate structure. This variable has been removed from the qt_sstate Example Code: See \src\dsp5680x\nos\applications\bldc_sensors\bldc_sensor.c The V.22bis API has changed and the v22biscreate (), v22bisdestroy () and v22biscontrol () functions have been removed. The v22biscreate() may be replaced with v22bisinit (). (See the Embedded SDK V22bis Library, Chapter 3 V22bis Library Interfaces for more information on the new API). The Caller ID API has changed and the calleridcreate (), calleriddestroy () and calleridcontrol () functions have been removed. The calleridcreate() may be replaced with calleridinit (). (See the Embedded SDK V22bis Library, Chapter 3 V.22bis Library Interfaces for more information on the new API). The GPIO lower level driver API has been improved to match the Posix I/O layer interface. This interface now allows for multiple bit manipulation. PC Master is now configurable to provide three levels of support to accommodate smaller Program and Data memory footprint based on customers requirements. Improved interrupt dispatcher to support static ISRs. Interrupt mechanisms supported by SDK have been documented. ADC driver optimized to provide faster scan rates. Current measurement of ISR servicing in Triggered mode is approximately 5.5 microseconds. A "convert23.h" include file is included to convert the naming conventions for SDK versions between SDK 2.3 and 2.2. It is highly recommended that SDK users review the name changes included here and update their applications to use the new names. This file is provided as a short term quick fix that will give users some time to determine the best time to convert to the new names with minimal schedule impact. This file is a temporary solution and will not be available in the next SDK version. At that time, the new names will become standard convention. If including the DSP Function Library and performing floating point calculations, it is necessary to turn off saturation mode to get the correct floating point results. Example Code: #include "port.h" #include "arch.h" void main (void) { bool bsatmode; float x=4.6, y=2.3, z; bsatmode = archgetsetsaturationmode(false); z = x/y; } archgetsetsaturationmode(bsatmode); The Narrow Band Filter application for DSP56824 target is provided as a reference only. DSP56F826 Platform - eeprom driver and application is written for the Microchip technology 25LC640 device. This device was replaced with a new device on the current EVM target system which will be supported in SDK 2.4 along with supporting documentation. DSP56F801 Platform - all software is preliminary and provided as a starting point for development.

9 Embedded SDK Release Notes Created SDK release to correspond to release of Code Warrior 4.0 and it's new features. This version of the SDK will not work with Code Warrior Embedded SDK Release Notes None File I/O on Windows NT/95/98 platforms bug reported in previous release determined to be user error and not SDK error. Solved Serial.exe problem by installing required DLLs. Installation will now check for the CodeWarrior version required for the SDK release and display a warning window if the wrong version of Code Warrior is installed on the user's machine. Fixed shortcut for PCMaster referenced in the Start Menu. Enabled IDE browser and S-record generation for all existing SDK Code Warrior projects and Stationery. The browser feature allows for quick access to files associated with current project. The access path for the Flash target in the ExtRam_Flash_Application in the 803 Stationery was changed from 805 to 803 directories. Added documentation for Clarke-Park algorithms in Motor Control library. Added documentation describing the software solution for nested interrupt enabling through the appconfig.h file. See Interrupt section in SDK Programmer's Guide. Added documentation for new Evaluation Boards that support Motor Control applications. During SDK installation, a certain amount of Temp storage space is required. The location of this Temp space is determined by the PCs environment variables TEMP or TMP. Windows Installer requires 89MB of Temp storage on the C:\ drive because that is where the window installer stores it's cache data. It also stores it's rollback data there. The windows installer will use which ever drive that it is registered on to store this data. The C:\ drive was chosen for the SDK. PC Master application requires that Internet Explorer 4.0 or greater be installed on the host PC. A "convert22.h" include file is included to convert the naming conventions for SDK versions prior to 2.2. It is highly recommended that SDK users review the name changes included here and update their applications to use the new names. This file is provided as a short term quick fix that will give users some time to determine the best time to convert to the new names with minimal schedule impact. This file is a temporary solution and will not be available in the next SDK version 2.3. At that time, the new names will become standard convention. The G165 application for the DSP56824 target does not work. The Narrow Band Filter application for DSP56824 target does not work. Disabled Browse Sequences for viewing HTML help system. This version of the SDK will not work with Code Warrior 4.0 Embedded SDK 2.2 Release Notes Added applications for motor control on DSP56805EVM and DSP56803EVM, including: Sensorless, BL DC Motor, Back-EMF, with Zero-Crossing Detection AC Induction Motor V/Hz AC Induction Motor V/Hz Closed Loop SR Motor using Hall Sensors

Added two application demos for implementing asynchronous mode. Added a V.22bis loopback test application. Added a non-blocking read mode to the DSP56824 BSP serial port (serialdrv.c). This feature is demonstrated in the V.22bis demos. PC Master application requires that Internet Explorer 4.0 or greater be installed on the host PC. A "convert22.h" include file is included to convert the naming conventions for SDK versions prior to 2.2. It is highly recommended that SDK users review the name changes included here and update their applications to use the new names. This file is provided as a short term quick fix that will give users some time to determine the best time to convert to the new names with minimal schedule impact. This file is a temporary solution and will not be available in the next SDK version 2.3. At that time, the new names will become standard convention.
