    I need to program an STM32F103 microcontroller. The project is simple. You receive some frames by serial port or canbus and you must write the text in a matrix or in LEDs. To control the LEDs, the PCB has an SPI driver so that only by sending via SPI the information will turn on the LEDs. I will be assembling here the pcb in parts. You will send me small examples to test hardware (canbus, serial ...
