Hi, 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/duxingkei33/orangepi_PC_gpio_pyH3

Hi, I have orangePI connected over HDMI to my TV but there is no video. If I connect orangepi with HDMI to DVI (to my monitor) the video is present. Can someone tell me what is wrong or how to set it up? The TV is Panasonic Viera (I have found similar question here: https://www.reddit.com/r/raspberry_pi/comments/5j89dk/having_trouble_with_hdmi_using_rasplex_and_a/) regards Peter
