NEXTION Displays



  • Hi everyone, i am just starting with RECALBOX, and wondered if there is a way for information to be sent over serial using the RPi4, when you change system, or select a game etc.

    The reason is i have a couple of nextion displays in the draw and wanted to use them like a marquee, if you havn't seen these before they take power and you programme them with the content and then via serial the content can change or if you press a button etc on the screem it will send serial to the pi 4, so no video processing and only 4 wires (VCC, GND, TX, RX)

    The NEXTION website is 👉 https://nextion.tech/ 👈

    If anyone has any ideas please let me know.

    Thanks

    Stu
