Uart communication with PC with Orange Pi PC Plus (H3)

[thuyle90]

Hi everyone,

I'm just a beginner with Armbian and OrangePi. I have some questions, please help me if you have time:

1. Orange Pi PC Plus has serial PIN J3 and GPIO Serial PIN -> What is the difference between them? J3 is maybe debug serial ?
2. I'm trying to write a python example to communicate between PC and board. I have also DB9 module and USB TTL but the problem is that I don't know from where should i start. 

 

thank you everyone , I'm waiting for your answer. have a good day

Leave UART0 which is used for debug as is. Console getty is running there. There are more uarts - enable them armbian-config -> system -> hardware.
