Noralf,
Thanks for the guidance on how to use the mi0283qt driver to run the
panel included in the Adafruit 2.8" capacitive PiTFT Plus (running on
top of a Raspberry Pi 3).
I am working with 4.16.0 (Fedora 28). I can get the driver to load, and
have console output appearing on it, but I have run into some issues
that I am unclear how to resolve.
Specifically:
1) If I change the rotation value to anything other than 90 (0x5a), the
screen output from the console is corrupt.
2) The resolution is set to 240x320, not the 320x240 that I expected.
3) pygame cannot run a display.set_mode call, always returning:
No video mode large enough for 240x320
When I run this python code:
import os
import pygame
os.putenv('SDL_VIDEODRIVER', 'fbcon')
os.putenv('SDL_FBDEV' , '/dev/fb1')
pygame.init()
list = pygame.display.list_modes()
print "List of modes: %s" % (list)
It shows an empty set ("List of modes: []").
Do you have any advice on how to resolve these issues?
Thanks in advance,
~tom
For debugging purposes:
I have the following device tree entry for the device (taken from dtc
-Ifs /proc/device-tree):
pitft@0 {
compatible = "multi-inno,mi0283qt";
buswidth = <0x8>;
rotation = <0x5a>;
bgr;
fps = <0x1e>;
reg = <0x0>;
pinctrl-0 = <0x10>;
debug = <0x0>;
dc-gpios = <0xf 0x19 0x0>;
spi-max-frequency = <0x3d09000>;
pinctrl-names = "default";
};
