Hi, thought I might share some details that could be handy.
I had a 7" Nextion board but wanted a little bigger, and also a brighter backlight.
So I checked the ribbon cable type on the 7" and it’s a 50 pin connection that’s the same as the 9" AT090TN10 screen which is the same resolution.
So took a punt and yes it works!
Only catch is it needs the backlight to be powered externally as the nextion cant provide enough current at full blast.
Using this as a dash in an 80s car hence the monochrome sort of look.
In order to get anti aliased fonts and the quickest possible response times I’ve made each set of characters a bitmap set, and if a number changes from say 495 to 496 it will update just that one digit to save pixel writes.
I’m using a mosfet to control screen brightness from a Teensy 3.6 and using averaged results from an LDR to do some automatic brightness adjustment which works rediculously well.
I’ve just bought a 10.1" Nextion Intelligent Series screen and hopefully a few of the features make my life a bit easier.
Currently I’ve got alarms which change the font colour which currently means I need seperate bitmaps in the different colour. Where as now I can dynamically change the font colour as I please. And transparencies will make my life a lot easier for having things overlap at the edges a bit and look a bit nicer.
Hopefully with the new screen the pixel write speed is a little higher.
Does anyone know if it is? I’d assume so with the higher processing speed.
