RPi USB Display

Dynamic Kernel Module Support

This directory contains a .deb file, plus the source used to build it, for rp_usbdisplay DKMS support.


Install with:

sudo apt install dkms raspberrypi-kernel-headers
sudo dpkg -i rp-usbdisplay-dkms_1.0_all.deb

Using the module

Once you've installed the module using the package above, you should test it.

Insert the module:

sudo modprobe rp_usbdisplay

Find which framebuffer (/dev/fbX) device the display is connected to:

cat /proc/fb | grep rpusbdisp-fb 

And display the test image on the display:

zcat shoplogo.fb.gz > /dev/<framebuffer_number>

If that works, add the module to /etc/modules by adding the line rp_usbdisplay.
