Firmware Tests

Unit testing specific functionality of each board.

Setup

Clone the repo, run mbed deploy from the root of the repo to get the mbed files, and then clone the submodules via git submodule update --init --recursive.

How to build a test

• Run make build board=$BOARD test=$TEST to compile and copy the .bin to out/$TEST_$BOARD.bin.
  • $BOARD must be one of:
    • cas (Common Avionics System)
    • bb (Black Box)
    • gs (Ground Station).
  • $TEST must be the directory name of the test to compile. One of:
    • uart_echo
    • led

Example: make build board=cas test=uart_echo

How to add a new test

Create a directory with the test's name and place its source code in there.

TODO: implement the below.

If the test requires a certain board, specify this by placing the relevant of the following before including any headers in the main file: #define REQUIRE_$BOARD, e.g. #define REQUIRE_CAS

For CAS tests, to include specific module pin definitions, add the following as needed:

• #define REQUIRE_CAS_PYRO
• #define REQUIRE_CAS_RADIO
• #define REQUIRE_CAS_PROP

How to add a new board

Add a new subdirectory to the pins folder with the board's name. If the board is a submodule of CAS, instead add a file titled cas_<module name>.h in pins/cas and edit the pins/cas/pins.h file to include the new module file when needed.

Relevant Folders

• pins: contains pin definitions by board.
• lib: Libraries submodule.
