STM32 Basic UART Usage
A few simple examples demonstrating some simple ways to use the UART peripherals on STM32F1 and STM32L4 chips.
echo: Re-transmitting characters over the
TXline as they are received on the
printf: Implement the C standard library's
printffunction to "print" over UART.
receive_irq: Use interrupts to receive characters more reliably than occasionally polling for them.
ringbuffer: Use a circular buffer to store a string of characters until they are ready to be processed.
All of the examples include a Makefile, and rely on the
arm-none-eabi GCC toolchain.
