I have a project to do and this consists of:
Arduino board which work as frequency counter and OrangePi PC which will be some kind of server (mysql, python).
The idea is to use UART port to communicate (send / recevie) datas from arduino to OrangePi using C, Java or python..
Here is my schema using LLC (converter between arduino and orangePC) (hope this will work )
Is there some example in C, python or java on how to use GPIO UART pin 8/10 on orangepi as serial port?
For now I have installed library from: https://github.com/zhaolei/WiringOP
and second for python from: https://github.com/d...pi_PC_gpio_pyH3
