STM32 HAL 101 – UART – Receiving arbitrary length string

Despite the fact that UART communication is the simplest and mostly used one, there are some problems or limitations that we can face when coming from other more complex communication protocols like, for example, USB. The first problem that we can find is the lack of having an efficient way to receive an arbitrary amount … Read more

Announcing the HW-USB-CAN – A Highly integrated USB-CAN Sniffer based on STM32
