MakAir Firmware

Versions

Pre-compiled binaries are available in the Releases section.

Code documentation can be found there.

In order to setup your environment and build the code, please follow the following commands (for MacOS):

brew install arduino-cli
arduino-cli config init --additional-urls https://github.com/stm32duino/BoardManagerFiles/raw/master/STM32/package_stm_index.json
arduino-cli core update-index
arduino-cli core install STM32:stm32@1.9.0
arduino-cli lib install LiquidCrystal@1.0.7 && arduino-cli lib install OneButton@1.5.0 && arduino-cli lib install CRC32@2.0.0

Then, compile the project:

arduino-cli compile --fqbn STM32:stm32:Nucleo_64:opt=o3std,pnum=NUCLEO_F411RE --verbose srcs/respirator.cpp --output output/respirator-production

In order to flash the firmware that you just built using the instructions above:

Plug your ST-Link programmer to the motherboard, and switch the motherboard to flash mode (switch position to flash mode on the motherboard);
Plug the ST-Link programmer to your computer, over USB, and fetch its device name via the arduino-cli board list command (we will call it {SERIAL_PORT});
Make sure that STM32CubeProgrammer is installed on your computer, and run:

arduino-cli upload --port {SERIAL_PORT} --fqbn STM32:stm32:Nucleo_64:pnum=NUCLEO_F411RE,upload_method=swdMethod --input output/respirator-production

Make sure to replace {SERIAL_PORT} with your serial port, which should begin with /dev/.

High-level configuration options are available and documented in includes/config.h.

Low-level configuration options can be found in includes/parameters.h.
