#1

the mcu have one uart1(u1)
which collection the data from the other machine
then the data that had disposal by the mcu transfer to q24PLUS from the same uart
is it avaiable?


#2

Do you mean, “is it possible to switch the UART of an external microcontroller between some external equipment and a Q24+” :question:

Yes, of course that is possible - but why on earth would you choose a microcontroller with only one UART when your application so obviously requires two UARTs :question: :open_mouth: :exclamation:
The extra complexity of messing about with switching a single UART will almost certainly end up making it more complex, more expensive, and more difficult than just using a 2-UART microcontroller in the first place!


#3

because the mcu have one uart ,so …
