I have implemented an emulated UART on STM32F2 using the sample program from STM32F4. The UART TX data output is correct. Until a HAL_Delay(100) is add. When added delay, the UART TX output appears corrupted as shown below. Why is the HAL_Delay affec...

Hi,I have design a custom board with the STM32F207VE. But I made a mistake in routing the UART TX as RX and UART RX as TX. Is there a way to change the STM32 UART TX port to an RX through the software?

My apologize, when I copy it over to this forum, I miss out the {}. In the actual code there is {} after the while() as shown below. int main(void){ /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Configuration---------------------------------...

I am calling it right after the while loop. while (1) { HAL_Delay(100); HAL_GPIO_TogglePin(LD2_GPIO_Port, LD2_Pin); LED_State = HAL_GPIO_ReadPin(LD2_GPIO_Port, LD2_Pin); HAL_UART_Emul_Transmit_DMA(&huart3Tx, tx_buffer_uart3, sizeof(tx_buffer_uart3));...

Hi just to add on, I am sending abcd in ascii and the HAL_Delay(100) caused weird ascii text to appear too. The data seems to be corrupted due to the delay. But if I remove the delay, the data is received correctly.

There is no error. The code runs smoothly. The transmit complete is also set. But I could not see the output through Hercules.exe. I am reading the UART output through the NUCLEO-F207ZG's ST-Link UART3. The NUCLEO-F207ZG has UART3 connected to its ST...

Sadly, I do not have sufficient time to lay out a new board. I will need RS422 as well, so operating in half duplex is not going to work. I have tried to convert F4 code to F2 on NUCLEO-F207ZG board but could not get it to transmit data. What could h...
