Question about function read() of Class STM32Hardware #5
thank you for your sharing!
I try to transplant this code to F4, I can not understand how the function read() get data from Uart, your code just Receive data one time in function init(), does the function init() run more than one time and is there any other function which can Receive data from Uart?
