This is the source directory for all STM32L452RE applications. This device contains an ARM Cortex-M4, and is also known as an L4.
This MCU typically implements higher power OreSat subsystems, such as Reaction Wheels and Magnetorquers.
After having installed the required toolchain components as described in
the Prerequesites section of the main README, it is good to test that
they all function as expected. This can be done by building and flashing
the app_blinky application that simply blinks an LED.
In order to accomplish this, from this directory simply execute the following:
cd app_blinky
make
make write
This should result in a clean no-error build, followed by a successful write to the board and a flashing green LED. If this all works, congratulations! Your toolchain is working and you can begin developing.
The template to copy for new applications is app_template. To create a new app, simply make a copy of the app_template directory and name it whatever you like. From this directory:
cp -R app_template app_<name>
Then, open the Makefile app_<name>/Makefile and edit the line PROJECT = to whatever name
you've chosen:
If building for a specific board, also update the BOARD = line to the
board defined in the boards directory.
PROJECT = app_<name>
At this point, you simply write code in source files under the sources
directory, include the appropriate header file in the main.c file,
and finally register your worker with the main OreSat application.
