  2. ** ChibiOS/RT port for Atmel AVR ATTiny167.                                **

  5. ** TARGET **
    6. 

  6. 

  7. The demo runs on a Digispark Pro board based on an ATtiny167.
    8.

  9. ** The Demo **
    10. 

  10. 

  11. A thread is used to print a message to the UART. The UART pins, must be
    12. 

  12. connected to an FTDI converter to see the message on a computer. The thread
    13. 

  13. also toggles the onboard test/status LED every second, the LED is connected
    14. 

  14. to the PB1 pin of the ATtiny167 MCU wich corresponds to P1 on the
    15. 

  15. Digispark Pro board.
    16.

  17. ** Build Procedure **
    18. 

  18. 

  19. The demo was built using the GCC AVR toolchain.
    20. 

  20. It should build with WinAVR too!
    21. 

  21. Just run the command "make" to build this example.
    22. 

  22. 

  23. ** Programming procedure **
    24. 

  24. 

  25. The ATtiny167 is pre-programmed with a bootloader.
    26. 

  26. Thus it can act as an USB device.
    27. 

  27. The Digispark Pro runs the “micronucleus” bootloader.
    28. 

  28. This bootloader comes with a command line tool which can be used to
    29. 

  29. program the board.
    30. 

  30. Form more details, look at the Makefile or the github repository:
