AMCU-L Host

Overview

This is the AMCU, an odometer device designed to simulate the AMS system.
The main controller is the RP2040, making firmware flashing easier; simply drag and drop to program, no third-party software is needed.
The power supply can be either soldered with a power IC or a power module, offering more flexibility. The power module is soldered on the back of the PCB and is a 24V to 5V 3A converter.
Because there are two different soldering methods, the actual component list is attached. The soldering method shown is the power module method; in this case, the power IC and its surrounding components on the front do not need to be soldered.
The completed software will be placed in the AP-AMS branch on GitHub at applenana/AP-AMS: A Simple Automatic Color Changing System for Totoro.

Excuse me, if I want to draw a picture on the LCD, how do I get the data of that picture?
That is, data is often represented by a two-dimensional array. Thank you.
