After reading: The answer suggests having to call HALUARTReceiveIT(huart1, uint8t pData, uint16t size) which I dont understand.I am familiar with AVR and an interrupt would fire, do what it needs to do, and then you could check variables it changed to see what has happened or retrieve bytes from a ring buffer.Why call this function Is it blocking I dont think it gets called because it always outputs 0s and doesnt change aTxBuffer0 to a 1.I added the void USART5IRQHandler() function because of the link above, but it did not have any effect.

You call it and it enables the interrupt and tells the low-level interrupt handler where to store the data it receives. The completion handler will be called when size bytes have been stored in pData. At that point you move the data into a different buffer, raise a flag that there is data, then re-enable the interrupt. ![]() In the real world you use an RTOS and use semaphores or some other signalling mechanism.). I am adding a feature to it. No - where can I find them 3) I saw a YouTube video where someone did this, but I only have Atollic TrueStudio installed. I think I am doing what you suggest in the code - can you take a quick look at it to see if I missed something Thanks for the help. Look at all of the development tools, evaluation tools, and software. Most of the examples are geared towards running them on one of their dozens of dev boards. Theyre like 10. Then go through the examples for the dev board. Stm32 Hal Uart Interrupt Example Serial Working AsThere are also plenty of tutorials on how to get serial working as well with cubemx. Its much easier to verify that the UART configuration is correct and that it can actually receive data without worrying about interrupt handlers, timing, bounce buffers, etc.
