Change Baudrate in runtime on old project - ATMega328
Posted: Tue Dec 18, 2018 5:03 pm
Hi guys,
I urgently need to fix an old project with FCV6 to change the UART baudrate in runtime from 38400 to 4800 and back,
using an ATMega328.
I found a post about this problem, but this solution doesn't seem to work.
Calling the FC macro within C-code with parameter 2 stops working with 38400 Baud,
but doesn't work on 4800 Baud. Changing it back to 38400, the UART doesn't work here anymore also.
Did I miss anything??
Any help would be appreciated!
Many thanks!!
