2 µvision2 IDE Project Management Targets let you create several programs from a single project. Each target has its own tool settings. With File Groups you organize source files into functional blocks. Select the microcontroller you use from the Device Database and µvision2 sets all necessary options automatically. Set memory parameters in the Target Tab and µvision2 configures the basic tool options including the linker/locater settings and the debugger simulation driver. You may set Tool Options for a Target, Group of files, or a single source module. Build Project During the make process, include file and source file dependencies are analyzed and only those files that have changed are built. Incremental re-translations are performed when global register optimization is enabled. Integrated Utilities µvision2 contains powerful features that help you complete your projects on time: The integrated Source Browser uses a symbol database for quick navigation through your source files. Use the detailed symbol information to optimize the memory types of your variables. Find in Files performs a global text search in all specified files. The Tools Menu allows you to start user utilities within the µvision2 IDE. A configurable SVCS interface provides access to Version Control Systems. The PC-Lint interface gives you advanced syntax analysis of your application code. The Infineon EasyCASE interface integrates block level code generation. Infineon s DAvE assists you with CPU and peripheral programming. DAvE projects can be directly imported into µvision2. The Device Database simplifies tool configuration and provides options that are relevant for the selected CPU. The Edit, Build, and Debug toolbar gives you quick access to important editor, IDE, and debugger commands. Use the Source Browser for fast navigation to definitions and references. Right-click to open context sensitive menus in local windows. In the Editor Window, you can access browser information or debugger commands & ST10 Development Tools

3 Editor & Debugger Source Code Editor The µvision2 editor includes all the editing features to which you are accustomed. Color syntax highlighting and text indentation are optimized for C source code. The editor is available while debugging your program. This gives you a natural debugging environment that lets you quickly test and correct your application. Breakpoints µvision2 lets you set program breakpoints while editing (even before the source code is compiled or assembled). Breakpoints are activated when you start the µvision2 Debugger and may be set on conditional expressions or variable and memory accesses. Debugger commands or debug functions may be executed when breakpoints are triggered. The Attributes column provides a quick overview of the current breakpoint settings and the source line status. Code coverage information lets you distinguish between executed and unexecuted program sections. Debug Function Language µvision2 incorporates a C-like function language that lets you generate and use: Built-in functions like printf, memset, rand, and other useful routines. Signal functions to simulate analog and digital inputs to the CPU. User functions to extend the command scope and combine repetitive actions. Variables and Memory You can point to a variable in the editor to show its value. Two docking windows display and allow the modification of: Local variables of the current function. User-specified variables in two different pages of the Watch Window. Program call tree in the Call Stack page. Up to four memory areas each in a different format. Workbook bar for quick document selection Attributes Bookmark No Executable Code Enabled Breakpoint Code already executed Current PC, next statement Disabled Breakpoint Selected line from Output Window Code is not executed Debug functions are created with the built-in editor and invoked by breakpoints, by toolbox buttons, or from the command line. Watch and Memory Windows allow review and modification of variables. The Call Stack Window shows the function invocation in the editor. 3

4 C166 Compiler The C166 compiler conforms to the ANSI standard and is designed specifically for the 166 and ST10 microcontroller families. Extensions incorporated into the compiler give you full access to all resources in your embedded hardware. Warning Messages Keil C166 performs extensive program flow and syntax checking and generates detailed warning messages that indicate: Mismatches in data types, pointers, and function arguments; Use of uninitialized variables; Dead code and dead assignments; Unused variables, labels, and functions; Constant expressions in conditions; and Missing return values. Memory and SFR Access Your program variables may be assigned to any address space supported by your target. The memory model determines the default memory selector used for variables. Note that you may always explicitly specify the memory selector for a particular variable. Even though the 166 is a 16-bit architecture, compiler options support byte-aligned access to int or long variables (even in C structures). Access to special function registers is provided by the sfr and sbit keywords. Interrupt Functions C166 lets you create interrupt service routines in C. Up to 128 interrupt functions may be included in each source module. Fast entry/exit code and register bank switching make C interrupt functions extremely efficient. PEC, FLASH, and More The PEC may be directly accessed in your C programs. Detailed examples for each 166/ST10 peripheral can be found in the documentation. Application Notes describe the extensions for in-system FLASH programming and the on-chip CAN. C166 Highlights Ten basic data types including single and double precision IEEE floating-point numbers Flexible variable allocation with memory selectors Fully reentrant code (including floating-point math) and library routines Access to bit registers including bit parameters and bit-addressable variables Sophisticated syntax checking and detailed warning messages Direct C support for interrupts, register banks, and PEC C-level access to all special function registers Register parameters and variables with global optimization 64KB near data area available in all memory models Support for the MAC unit Optimum bit-field access with 166 bit and BFLD instructions C support for byte-aligned int, long, float, and struct variables Built-in interface for the RTX166 real-time operating system Extremely efficient use of the extended instruction set Supports all variants of the 166 and ST10 family Complete debugging information included in object modules Supported by all emulator vendors Memory Selectors Selector Address Space near...16-bit address, up to 64KB DATA and CONST space idata...on-chip RAM, fastest variable access. bdata...bit-addressable RAM. sdata...system page (0xC000 to 0xFFFF) for XRAM objects. far...32-bit pointer with 14-bit address calculation. huge...32-bit pointer with 16-bit address calculation, generates optimal code on current devices with extended instruction set. xhuge...32-bit pointer/address calculation, unlimited object size. Memory Models Memory Variable Function Model Selector Selector TINY near near SMALL near near COMPACT far near HCOMPACT huge near MEDIUM near far LARGE far far HLARGE huge far In every memory model the L166 linker allows flexible assignment of the four DPP registers to the NEAR DATA and NEAR CONST areas. This provides up to 64KB for fast near variable access. In the HLARGE and HCOMPACT memory models, the memory appears as a linear 16MB address space & ST10 Development Tools

5 Code Optimization The C166 compiler optimizes your C code with the expertise of an experienced assembly programmer and uses the following optimizations: General Code Optimizations Constant Folding Common Subexpression Elimination Strength Reduction Control Flow Optimization Global Constant Propagation Register Variable Usage Parameter Passing in Registers Loop Rotation Dead Code Elimination Common Tail Merging 166-Specific Code Optimizations Peephole Optimization Switch-Case Optimization NOP/DPP Load Optimization Bit-field Access Optimization MAC Unit Support The Multiply/Accumulate Co-processor that is available in some 166/ST10 variants is fully supported by the Keil tool chain (using the MAC compiler and assembler directive). The C166 compiler improves execution speed of DSP algorithms by replacing the MUL and MUL/ADD instruction combinations as well as structure copy operations with MAC co-processor instructions. You may use C166 intrinsic functions to write DSP algorithms that use the MAC instruction set at the C program level. C Run-Time Library The C166 run-time libraries consist of over 100 functions all of which are reentrant. The libraries support all of the ANSI C routines that are consistent with the limitations of embedded applications. Intrinsic routines are provided for the following 166-specific instructions: einit, diswdt, idle, nop, prior, pwrdn, srvwdt, trap, bfld, testbit, testclear, ror, and rol. The C166 Tab shows compiler options and lets you select the level of optimization. Global register coloring performs incremental re-translations that enhance register usage.

Code was executed on C167 20MHz CPU clock, 16-bit non-mux BUS. A166 Macro Assembler The A166 assembler supports all 166 / ST10 and MAC instructions and provides the following functions: Standard and MPL macros with conditional assembly. 64-bit arithmetic; jmp & call instruction optimization. Extensive section directives and use of DPP registers. With the SRC directive, the C166 compiler generates assembly source files. Inline assembly may be included using the asm and endasm pragmas. 5

6 RTX166 Real-Time Kernel The RTX166 multitasking real-time kernel makes implementing complex, time-critical software projects easy. RTX166 is royalty free and is fully integrated into the C166 tool chain using the standard 166 stacks. RTX166 adds no overhead to your C code and requires no run-time libraries. RTX166 Full supports fast tasks, standard tasks, and includes CAN support. Flexible mailboxes may be used with memory pools for inter-task communication. RTX166 Tiny is a reduced functionality kernel that fits on single-chip systems. Both let you create and delete tasks, send and receive signals and messages, and perform other management operations. Task (Context) Switching Events and Interrupts Round-Robin: Each task runs for a defined time slice. When a task s time slice is up, the next task starts. Preemptive : The task with the highest priority runs until it is preempted by a higher priority task or until it delays waiting for an event. RTX166 supports the following events: Timeouts: Intervals: Delay for specified timer ticks. Delay for an interval of time. Signals: Coordinate inter-task operations. Messages : Interrupts : Pass messages between tasks. Handle hardware interrupts. Semaphores : Share limited resources. Interrupt functions are supported and may send signals and messages to and from tasks. Since RTX166 Full never disables interrupts, there is no impact on the response time of interrupt service routines. CAN Interface A CAN Library supports the on-chip CAN controller of the 166 devices and allows you to send and receive messages via a CAN network. Using the CAN interface, you can easily implement multiprocessor designs & ST10 Development Tools Overview of RTX166 Routines Task Management Routines: create-task, delete-task, changepriority, pass-task, running-task-id, and running-task-priority. Interrupt Management Routines : attach-interrupt, detachinterrupt, enable-interrupt, disable-interrupt, and wait-interrupt. Signal Functions: send-signal, clear-signal, wait-signal, and isr-sendsignal. Semaphore Functions : create-semaphore, delete-semaphore, sendtoken, and wait-token. Mailbox Functions : creat box, delet box, check-mailbox, send-message, wait-message, isr-send-message, and isr-recv-message. Memory Management Functions : create-pool, check-pool, getblock, and free-block. System Clock Routines: set-slice, delay-task, set-timeout, and check-timeout. CAN Communication Routines : task-create, hw-init, def-obj, defobj-extd, undef-obj, stop, start, write, receive, def-buf-size, bind-obj, unbind-obj, wait, request, read, get-status, and get-errors.

7 Testing Your Programs The µvision2 Debugger provides all the usual source-level, symbolic debugging features and includes trace history, code coverage, and complex breakpoints. The DDE interface and script language support automated test batches. CPU & Peripheral Simulator µvision2 integrates high-speed CPU simulation with on-chip peripheral simulation for the 166 and its derivatives. Even the MAC unit is fully simulated. I/O values may be reviewed and modified directly in peripheral dialogs. Dynamic input values may be generated with user signal functions that you write using the built-in C- like macro language. µvision2 gives you the choice between Simulator, Monitor, and Emulator. Target Monitor µvision2 comes with a configurable Monitor that lets you test your software in hardware. The Monitor operates in different modes: Bootstrap: The Monitor downloads into RAM of the target system. The best mode to start with (baud rate is auto-adjusted). Simulated UART: Two un-used I/O pins are used for PC communication. Requires that the Monitor is loaded into ROM. OCDS/JTAG: This new, high-speed interface uses the On-Chip Debugging System available in new 166 variants. The Monitor is only 50 Bytes! Emulator Interface The µvision2 debugger interfaces directly to the Hitex DProbe emulator. All emulator features are available in the IDE. You do not need to learn any other environment. MCB167/NET is a high-speed single-board computer that supports all C167 variants while providing both a dual CAN interface and an Ethernet controller for TCP/IP applications. The board is in-system programmable with 167 Flash versions or off-chip Flash ROMs. A Performance Analyzer provides detailed timing statistics of your code. Serial communication, A/D converter, and Port I/O are all fully simulated. The Monitor Setup Dialog provides a number of monitor variants and configurations for popular evaluation boards. MCB167/NET CPU Board with Ethernet and CAN MCB167/NET is designed with high-speed parts and allows you to use future 167 versions at up to 50 MHz.
