Cannot transmit every characters through UART

Question

I am using stm32f0 MCU.

I would like to transmit every single byte received from the uart out of the uart. I am enabling an interrupt on every byte received from uar

Answer 1

You should make a tx array buffer as well, and use interrupt for writing as well (The first write if not enabled yet, should be sent immediately).

There should be examples of this for STM32 around.
