I'm traying to comunicate via modubs protocol. I've done the protocol to comunicate the slave with the PC using the UART4, and it works fine. But now, i have to comunicate a master module with a slave using the UART0.
The comunication works fine when using the UART4 port, but when changing to the UART0 port, it doesn't comunicate. Is there something different that I must do when using the UART0 instead of the UART4?
I now that the UART0 uses the core clock and the UART4 the bus clock, but in this case, both have the same frecuence.
