This is an old revision of the document!
In this article, we will create a custom DMD.
The result
Step 1 : buy the hardware
The list :
- 2 dmd pannels (don't forget to choose 2 of them) DMD Panels
- 1 esp32 and its shield ESP32+shield
- 16 male/male 10cm jumpers Jumpers
- 1 power supply Power supply
- 1 plug Plug
You probably already have a plug at home. Total price including shipping : 39€ (on 2024 april 8).
Step 2 : plug the hardware
Step 2.0 - external links
The original tutorials are not related to batocera.linux, but may be very usefull to get some informations. The hardware part is the same for batocera. Just configuration actions/software at the end changes.
Step 2.1 - Cut and prepare the power wire
Step 2.2 - Plug matrices together with data and power wire
The data and power wire for the matrices are delivered with the matrices. Just plug them. Note that white arrows must go from left to right.
Step 2.2 - Plug the power
Plug the 220V power on the AC. Take care of colors. Phase (brown) / Neutral (blue) / Mass (yellow/green).
Plug the 5V. Take care of colors.
The orange screw on right can be used to adjust the 5V voltage. It is usefully in case the image is not perfect. Too much voltage make the image not perfect.
Step 2.3 - Microcontroller
