Hello Anchorized,

All of our intelligent modules use packet-based communication. This means all commands must be sent using the proper packet structure to communicate with the display.

The packet structure is well documented in the CFA635 datasheet (which can be found here: https://www.crystalfontz.com/products/document/4129/CFA635-xxx-KL.pdf) but, if you are looking to avoid writing a software utility to communicate with the display, we've had great luck working with lcdproc (https://archlinux.org/packages/extra/x86_64/lcdproc/) to communicate with the display.

In fact, I wrote a tutorial many years back that showed how to do just that:
Granted that was for Ubuntu and you are using Arch but the lcdproc documentation is pretty good and may get you up and running.

Let me know if you run into any roadblocks. I'm not an Arch user but have used both lcdproc and the CFA635 pretty extensively.

Good Luck!
Max
