Hi all,
sorry , a bit off subjet..
I have a rpi 4
I have several HAT , pypilot, RS485 and more, that use UART.
I did not know UART pins cant't be shared, and since there is more than one UART on rpi 4 I thought I could use all of them.
now I understand that they all use the same UART and thereforce cannot be used at the same time.
exept MAYBE, if I don't use them as HAT directly connected on GPIO, but connect them on a breadboard and chose to connect each of them on différent UART pins.
is it an option or not ?
as you may notice, I am still a noob in the raspberry world, but I have enough knowledge in computing and electronics to learn
thanks for your advises.
regards
Gildas
