using UART

[gildas declercq]

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
