I'm currently running a teensy 4.0 ..rev d audio board and an ili9341 display no issues.... touch working as well.. ... first time working with a TFT display so its a simple one ..
I've been reading the wiki by Sumotoy trying to get my head around the 8875 interface ...
yes I've purchased the 5" buydisplay ER-TFTM050A2-3-3661 with 5v/ 4 wire SPI ..(sitting in my hot little hands)
If I reconnect the existing SPI pins and associated reset /interrupt which were connected to my ili9341 and swap the library out should this work?
I'm currently running the conventional pins on the teensy4
9 - DC
10 - CS
11 - MOSI
12 - MISO
13 - SCLK
for SPI
I realize I'll have to power the display with external power ..... not from the USB port...
I'm trying to understand the potential conflicts with the Audio board and SPI ..( do I have to introduce the additional ttl logic for the tri-state SPI of the ra8875 if I'm using the audio board)
I'm also having confusion in one portion of the wiki as there is a red note indicating the version of the display I have is 3.3v "only" and not 5v ... could use a little direction there ..
Sorry for all the questions ...quite a step up from the ili9341 for me..
Thanks in Advance...!!!
