Quick Question - and is there a text to learn to program Nextion?

[KE2SJ]

I'm using the standard Pi-Star layout for my screen (GXXXXX). I'd like to modify it so the call of the person I'm chatting with remains on the screen throughout the QSO in D-Star Mode and DMR Mode. There's gotta be a way, and I'd love to be told how. But I'd also love to find a text on how to program Nextion so I can build/code my own HMI. Is such a text available?

Rob van Rheenen, PD0DIB, has some great documentation. Visit his Nextion Ham-Radio Screens  Facebook group to find it: https://www.facebook.com/groups/Nextion/

Thanks for your reply, Yes, he does have great documentation and I'm a proud member of the Facebook group. But I'm looking for something that will teach me not only to modify basic parameters, but to program my own screens in Nextion code. In addition to finding out the answer to my question of what Pi-star pull-down option should I use screen layouts like those of PIODIB and others. Still searching for that that text and answer. I know it must exist...
