Anyone Helps me!Anyone please show the basic USART's tx/rx code. Or check my CubeMX Project File.HAL's USART won't work.it code is generate from STM32Cube.There is two USART, one(huart2) everytime send data to STM, another(huart1) everytime wait comm...

I've tried as mbed, it uart transmission succeed. but mbed couldn't set GPIO as free.so I have to make program in HAL. Circuit is not wrong. May important problem in CubeMX setting. (it may not HAL, because source code is very simple.)Anyone help me...

It seems complex problem. Could you help me?I think mine circuit is not wrong but, source code and CubeMX are correct, I have to doubt circuit.But there is no weird point. and I modified circuit too simple. change the cable and so on.Whatsover, I dou...

Thanks. then, you mean, mine CubeMX settings is not wrong?I've ran examples, I noticed funny thing that I referenced source that It dedicated huart2, but run process always go "USART1_IRQHandler", not USART2_IRQHandler."UART_TWOBoards_ComIT", and r...

And when runs after ` HAL_UART_Receive_IT`, Timer callback won't run. but `while` in main process working.it seems USART bring to freeze on STM's interrupt schedule. I hope this will be hint to solve this problem.

I understand `HAL_UART_Receive_IT` does regist myself as next callback. but `HAL_UART_RxCpltCallback` runs first call `HAL_UART_Receive_IT ` only.it means nothing uart coming. and none response to send message, it wouldn't connect USART, huh?But this...
