@Pavel A. I was able to debug the code using ITM and found that the data was not getting received as expected. But after changing the logic like this it started working.if (HAL_UART_Receive(&huart1, &rx_data, 1, HAL_MAX_DELAY) == HAL_OK) { HAL_UART...

@Techn I did check the signal grounds and everything is proper. I also tried the HAL_GPIO_TogglePin. It's working fine, also the processor is able to transmit data via UART and I was able to get it printed on CoolTerm.

Well, my question is how to make the uart code work as I'm not sure what am I missing. I'm using Nucleo-H723ZG (with genuine ST-LINK on-board) to debug the code as I don't have sepate debugger to test on black pill. So, how can I print the variables ...

Okay, So I tried debugging the code with debugger. I'm able to see that the if statement is not satisifed. I'm new to STM32 and I'm not sure how to print the values on debugger console. Can anyone please help me with that? Also, check the image for r...
