So i've look at the lib projet and the gameduino x3 screen. That look quite good, but i just don't figure how can it be used/config outside of the touchscreen. Like if i want a simple sensor to display the value on screen and a potentiometer to turn a gauge needle... is it possible ? I haven't seen example of that. Is it a matter of 2color widget or to load 2 image as 1 for the gauge frame and 1 for the needle that will be move somehow..
And for connection, like with an esp8266 or esp32.. Is is just to connect SPI pin and it's all working ? with the 3.3v of course. It's because i was looking at this screen FT813 eve2 engine. NHD-3.5-320240FT-CSXN-CTP
