Next the script will ask you what kind of adapter you’re using between the Pi and RGB matrix: either an Adafruit RGB

Matrix Bonnet, or RGB Matrix HAT with RTC. If you select the latter, you’ll also be asked if you want to install additional

drivers for the realtime clock.

Then you’re asked whether you need the

absolute best image possible

from the LED matrix, or can accept slightly

reduced quality for the sake of simplicity.

The “quality” option comes at a cost. First, you need to

solder a jumper wire between GPIO4 and GPIO18 on

the Bonnet or Hat board. Also, the normal sound output

of the Raspberry Pi must be disabled. You can still use a

USB sound adapter if needed, but audio over HDMI or

from the 1/8" jack will not be present.

The “convenience” setting requires no changes and sound still works. For many casual projects this might look good

enough. There’s an occasional bit of flicker from the matrix, that’s all.

If you’re not sure, or if you just want to get started experimenting with your new gadget, select “convenience” for now.

You can make the change and reinstall the software later if needed.
