I have been weeks now trying to do what seems like it should be straightforward. I want to display fairly large numbers on a 3.5" LCD display.
So i bought a 3.5" display. Turns out it has an ili9486 driver chip, and won’t work with an Adafruit library. I have to use MCU Friendly. But that does not allow for large text. According to what I read in this forum, I must use an ili9481 chip.
My new 3.5" display came in, but it has several options as to chips (9486,9481,9341,9488). But it only seems to work if I use that stupid mcufriend library. This leads me to deduce that it is set to 9486. I ran the reg read .ino, and that serial output image is attached.
from what I can see, if I want ili9481, i must use 0x00BF register, but I don’t even know what that means or how to do it.
I think if i can get the display to work with the Adafruit library I can use the adafruit font modifier to get what i want as far as text size goes. Can someone tell me, in pretty simple terms, what i have to say in the sketch to select ili9481 ?
