using UART - gildas declercq - 2023-09-24 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 |
