stm32f3-robotics is a C library typically used in Internet of Things (IoT) applications. stm32f3-robotics has no bugs, it has no vulnerabilities and it has low support. You can download it from GitHub.

STM32 F3 discovery board code ===. The most interesting files are: * main.c * gyro.c and compass.c handle the sensor stuff, (but some of the compass heading calculation is still done in main.c) * interrupts.c is actually just renamed, it was (confusingly) called stm32f30x_it.c, but it contains most of the interrupt handlers. * usart.c contains USART output routines The USART interrupt lives here, not interrupts.c. * newlib.c contains all the newlib (libc) interfacing stuff, including system call stubs, etc. newlib.c allows you to use printf as usual, whilst having the output come out of USART. Obviously newlib.c assumes that you’re using the newlib library, which you need to have configure’d with --disable-newlib-supplied-syscalls. If you get a hard fault exception when printf`ing a `%d bigger than 10, you have to re-configure and recompile both gcc and newlib with hard floats: --with-cpu=cortex-m4 --with-float=hard --with-fpu=fpv4-sp-d16 --with-mode=thumb.
