so what do we currently know about our current predicament we're trying to get serial communication working between two boards they are hooked up in a way where I can be reasonably certain that the boards are configured correctly I have connected the TX pin of the F7 with the RX pin of the F0 the F7 is supposed to send a character whenever the user button is pressed the F0 is supposed to light up its own LED whenever it receives data on the RX pin, which should be causing an interrupt handler to be called the USART connection is unidirectional exit
