pi-eyes-gc9a01a

A version of Adafruit's Pi_Eyes project with support for gc9a01a based 240x240 round displays.

In particular these CMU ROUND 1.28IN RGBLCD DISPLAY - Communica [Part No: CMU ROUND 1.28IN RGBLCD DISPLAY]

Currently this only includes the fbx2 changes and code as the original Python code for generating the eyes no longer works. (Pi3D issues)

This code will take the framebuffer (/dev/fb0), split it and send each side out to the two displays.

You can enable gc9a01a mode by running fbx2 -g

Below is a working /boot/config.txt for my Pi3B, this is based on the changes made by the original install file however I needed to comment out the following to get access to the framebuffer.

# Enable DRM VC4 V3D driver
#dtoverlay=vc4-kms-v3d
#max_framebuffers=2

# For more options and information see

# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.

# uncomment if hdmi display is not detected and composite is being output
hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
hdmi_group=2

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
