Matouch 1.28 ToolSets
1. Introduction
MaTouch 1.28” ToolSets are series of ESP32-based products mainly consist of MaTouch 1.28” controller and kinds of functional expansion such as Dimmer/ Relay Controller/ Motor Driver, etc. It’s designed as tools to control/drive these actuators directly while also keep open hardware/software, which make it possible for users’ remaking and integration to other field projects.
2. How to use?
2.1 Preparation
The Matouch 1.28 DevKit includes a controller and six functional kits, each designed to work in conjunction with the controller. To get started, you'll need one controller and at least one functional kit of your choice.
2.2 RGB Matrix Panel Driver
Hardware preparation:
- MaTouch 1.28" Dev_ESP32S3 Controller
- MaTouch 1.28" Dev_RGB Matrix Panel Driver
- 64x64 RGB LED Matrix
- SD card
- 5V 6A Power Adapter
1.Use the cable to connect the left side of the arrow to the expansion board. The red wire is connected to the 5v of the expansion board, and the black wire is connected to the GND of the expansion board.
2.Save the file you want to display into the SD card, then insert the SD card into the controller.
If you just need to test it, you can download the gif from here.
Note: You can only save in the first directory, you can't create a folder to save in.
Currently only supports gif and txt files, if you want to display other, you need to modify the programme yourself.
When you want to save your own files, the length of the files must be 64 * n, the width must be 64.
For example, if you connect only one RGB Matrix Panel, your files must be 64 * 64, and if you connect two, it will be 128 * 64.
3.Connect to the expansion board using the 5V 6 A power adapter and toggle the switch to the ON label.
Usage:
This RGB Matrix Panel has two functions: switching GIF images and brightness adjustment.
1.You will see the name of the gif file you have stored in the sd card, and you can rotate the encoder to switch the GIF or txt files.
2.Slide the screen left to switch to the interface of adjusting the brightness, which can be adjusted by rotary encoder.

About stepper motor subdivision
The default step angle of the 42 stepper motor is 1.8°.
The code sets the default value of the step angle to 200.
int unit_x = 200; //Motor 1
Not subdivided to turn a circle to 360/1.8 ° = 200 steps, corresponding to 1 step 1.8°;
Here to set the value directly to 200, so twist it to turn 200 * 1.8 = 360°
If it is 16 subdivisions, one turn should be (360/1.8)*16=3200 steps, corresponding to 1 step 0.1125°.
Here to set the value directly to 200, so twist a turn on the turn 200 * 0.1125 = 22.5°
Subdivision can be changed by changing the pcb wiring cap:
| SW1 | SW2 | Function |
|---|---|---|
| connected | connected | 16 subdivision |
| disconnected | disconnected | 8 subdivision |
| connected | disconnected | 64 subdivision |
| disconnected | connected | 32 subdivision |
