I want to use PLC, I wonder if Nextion can support Modbus like other HMIs? Recently many new TFT LCD products are starting to support Modbus and Canbus.
It has a crc function for modbus other than that its up to you write code on the display.
Do you have a detailed explanation of the CRC function or a link to a similar example? I didn’t search for very specific ones.
There was a post a while back about the crc function when released but you need to go through the language reference and see how it is used but the nextion is still just a serial device with no bus functions ie address etc you would have to implement that.
