144LED array development board based on IS31FL3732

Overview

Based on the test version of IS31FL3732, there have been a lot of ships recently, and they all use this kind of chip, so I just made it and played with it, hehe~

SDB is the enable pin, active high. The power supply voltage is 3.3V. The chip address is determined by the address jumper. The lamp position naming is the same as the official manual (pdf file below), which is easy to find. You can also modify the file yourself.

The PCB file is drawn for AD16. I was not used to the EDA traces, so I left it. The PCB file has been printed and verified.

9.10 update: 3D packaging update

Screenshots, Registry, IE Issues
Hello everyone! The last question I asked here was: the screenshot of the interface, the screenshot image is saved in the hard disk. The question I want to ask now is: the platform my program runs on
The intermediate challenge is obviously more difficult than the beginner one.
The test took about an hour. It's really difficult.This FLL should be phase-locked. I don't know if A is the right choice.I've only heard of HID. Many microcontrollers have it. I haven't researched it
