cam-fisa

Cannot remember if I followed OS setup for TFT display or if I used their bookworm image. https://www.waveshare.com/wiki/2.8inch_RPi_LCD_(A)#For_Bullseye_32-bit_and_Buster_Systems

My module seems to have max of: 2592x1944

WaveShare display

key 1 = pin 7 = gpio4

key 2 = pin 16 = gpio23

key 3 = pin 18 = gpio24

key 4 = pin 22 = gpio25

To test display

1. sudo apt install fbset fbcat
2. sudo fbset -fb /dev/fb0
3. sudo cat /dev/urandom > /dev/fb0
4. sudo dd if=/dev/zero of=/dev/fb0

For cam

sudo apt install libcamera-apps python3-pil python3-evdev -y

Fix for needing to run app as sudo due to dmaheap permissions

1. sudo nano /etc/tmpfiles.d/dmaheap.conf
2. Enter the following:

# Fix DMA heap permissions for libcamera
z /dev/dma_heap/system    0660 root video -
z /dev/dma_heap/linux,cma 0660 root video -

3. sudo systemd-tmpfiles --create
4. sudo reboot
5. ls -l /dev/dma_heap/ and group -> Check group permissions exist for heap and user is in videos group
