3 The Microcontroller The Microchip 16bit microcontrollers present: 16 bit (data) modified-harvard RISC architecture; High-performance MCU capability; Integrated DSP capability (dspic families); Separate program and data buses; Powerful peripherals on chip; Idle &Sleep modes; Switch between clock sources in real-time time; Flexible Interrupt t structure. t

4 dspic microcontroller Microcontrollers t basic features: 16-bit core up to 40 MIPS a 80 MHz; Integrated DSP Module; 6KB-256KB Flash Program Memory; 256B-32Kb RAM Data Memory; Up to 4 DMA channels; Up to 8 16-bit Comparators; Up to 8 PWM Generators; Upto816bit 16-bit Timers (32 bit mode).

5 dspic microcontroller Microcontroller I/O capabilities: Up to 86 I/O pins16 channels; A/D module with: Up to 2 A/D converters; 500KSPS@12-bit 1MSPS@10-bit Motor Control PWMs Quadrature Encoder Interface Analog l Comparators

6 dspic microcontroller Microcontroller Connectivity: UART ports (IRDa support) CAN bus version 2.0A/B Data D t Convert Interface (I 2 S/AC97) Parallel Master Port I 2 C / SMBus SPI bus

7 Why another Evaluation Board? Typically, y, demo boards are: big! limited pin counts MCU most of the pins used for LEDs, buttons, difficult to expand! poor connection with development PC FLEX: small size (7x10 cm) 100 pin dspic all pins free on connectors 2.54 pitch, no SMD expertise required! PIC18 for USB connection

8 FLEX: other features switching power supply resettable fuses dspic programming g from USB daughter boards (Thru Hole, CAN, SPI, Ethernet, RS232, RS , RS , [other coming soon] ) support fot ERIKA O.S.

9 FLEX: versions Full Light g

13 Why an embedded O.S.? It reduces the complexity of the application; It increases the reusability of the code; It simplify the SW debugging; g It reduces the time to market:...

14 Why a Real-Time embedded O.S.? An embedded applications typically presents a lot of interactions with the environment; That requires a management of the response time to an external event.

15 ERIKA Enterprise ERIKA Enterprise OSEK-like RTOS for minimal embedded systems 1-4 4KbROMf footprint t enhanced scheduling algorithms support for debug tools (Lauterbach, ICD2) RT-Druid RTOS configuration using OSEK OIL schedulability analysis integrated in eclipse.org

16 Erika - supported MCU Currently available as a product for: Microchip dspic Atmel AVR Altera NIOS II (with multi-core support!) Also available for: ARM7TDMI (Samsung KS32C50100, Triscend A7, ST Janus, ST STA2051) Hitachi H8 (RCX/Lego Mindstorms) Tricore 1 PPC 5xx (PPC 566EVB) C167/ST10 (Ertec EVA 167, tiny/large mem. model)
