I have built and tested my v5, tuned in WWV and it was spot on..? next on the list is to test TX..? need to get the antenna to a happy SWR

I was given 2 20x4 blue screens, it comes up fine with 2 lines by about 16 wide.? Is there a setting in factory firmware for the 4 line screen? CEC v1.121 still have settings for it?? Did I see a reference to using a second screen?? Trying to do what I can with what I have even though the nextion screen looks so cool..

You have to do some alterations in the firmware sketch yourself. Line 1 is indicated as 0. Line 2 as 1. Line 3 and 4 will then be 2 and 3. Line 3 and 4 you have to add. And what data you want there. There is no setting that will do it for you as far as I know.

Thank you all..??

Looks like I need to compile/download CEC v1.20 .. does it default to 20x4 screen as in v1.072?
I have not found a manual after v1.072

Is I2C a different screen or different way to talk to the same screen?

What a fun new adventure..
