I have a cute project running called AYP that is currently running on Arduino UNO: www.autoyoke.com
As I'm trying to switch to Teensy4.0, I started with implementing this example:
https://www.pjrc.com/store/display_ili9341.html
Using this diagram:
Vcc to 3v3
GND to GND
CS to pin 10
RESET to 3V3,
D/C to pin 9
MOSI to pin 11
SCK to pin 13
LED to 3v3
MISO to pin 12
The screen stays blank.
The serial output shows:
START
ILI9341 Test!
Display Power Mode: 0xA8
MADCTL Mode: 0xA8
Pixel Format: 0xA8
Image Format: 0xA8
Self Diagnostic: 0xA8
Benchmark Time (microseconds)
Screen fill 205451
Text 9318
Lines 70391
Horiz/Vert Lines 17466
Rectangles (outline) 11202
Rectangles (filled) 427139
Circles (filled) 67203
Circles (outline) 48587
Triangles (outline) 16541
Triangles (filled) 146009
Rounded rects (outline) 17825
Rounded rects (filled) 472617
Done!
Seems bizarre that all those codes are 0xA8. How can I find the meaning for that? Maybe that's why it's not working.
Thanks!
