I'm new on Nextion display. I made a new project to communicate with my RPi. It's working fine with python code. My question is, while Rpi is booting, can i make a waiting display on Nextion? I suppose i need to make a page0. Then, when my python run on RPi send a command to nextion, to change to page1 (this is a interactive page, page 0, only is an image "Waiting for boot").
I don't know how to read serial in my project of Nextion Editor, can somebody help me?
Sorry my english...
I don't understand what are you meaning. When I plug my Rpi, Nextion displays shows the main page instantly, but my code is not running yet. I must wait about 1 minut to start my python and comunicate with my Nextion display. How can I send from python to change page when starts running?
The documentation says clearly that you have simply to send the "page 1" command plus the 3 termination bytes over serial from the RPi/Python after booting is complete and your code is running:
