Reproduction of CV engineer keyboard (analog keyboard based on CH552)

Overview

I saw the cv engineer keyboard when I was watching videos on Bilibili. I went to a certain store and saw that it costs 3-40 yuan each, so I thought I might as well make one myself. The key switches cost 8 yuan for 10 pieces, the single-chip microcomputer costs more than 2 yuan, and the resistor, capacitor and type-c interface transistor only cost about 1 yuan in total. The board is from Jialichuang, and the cost per unit is not counting the keycaps and casing. About 6 yuan. The program part was developed using Arduino and was completed in less than half an hour. It can also be modified into one-click macros in the future.

Has anyone used an LCD screen with driver IC OTA5180A?
This is the first time I use this type of LCD screen. In addition to the data I/O port, it only has DISP, VSYNC, HSYNC and DE I/O ports. I would like to ask if any experts have used this type of LCD,
Can I give each node a fixed network address during the Zigbee networking process?
In the ZigBee networking process, can I give each node a fixed network address instead of an algorithmically assigned address or a MAC address?
Can we talk about ARM7 issues?
I recently ported the TCPIP protocol to LPC2292. During the test, I found that the program ran away. After looking for the cause, I found that when assigning the first data to a structure pointer poin
