Transponder firmware

This is a vanilla Eclipse CDT project. Import it into your workspace and (assuming you have ARM cross compiler installed) it should be straightforward.

The application is mainly interrupt driven, with a single event queue being dispatched by an RTOS task.

Key updates

  • Starting with board 6.1 you have the option of using FreeRTOS 10, but not by default
  • DFU can be achieved by jumping directly into the ROM bootloader, so there is no need for hardware to manipulate the BOOT0 pin
  • The TX_DISABLE signal is now supported
  • Board 9.3 adds 3 "status" (LED driving) signals for GPS, RX and TX
