LED Display

Overview

I recently built several minimum system boards, and after finishing the microcontroller, they looked quite nice under fluorescent lights. However, one day I happened to hold one up to the sun and noticed some adhesion between the joints. This inspired me to create a board with integrated lighting to inspect the soldering of each joint. The board has a simple structure and can be directly fabricated. It can also be adjusted to meet specific needs.

SoSO said that not many people use heat transfer in the forum, so I will share a heat transfer board that I just finished last night.
Cause: I need to do an experiment of acceleration sensor for work. The fastest time for PCB manufacturer to make the board is 1 week (expedited). Usually it takes 1-2 weeks to delay the development cy
Is it that difficult for the Weifu emulator VW.EXE to support V8 and V9?
Other emulators already support Keil C V8~9, why is Weifu's emulator still stuck at V4~5? It has been almost 10 years since WAVE6000 to V8, and Weifu still has no improvement?
LED lighting design analysis
[hide]To design a product, we must first determine whose LED package structure to use; then consider how to adapt to these packages; We have few opportunities to choose, and the optical structure is b

Bluetooth Protocol
I was also looking for Bluetooth protocols some time ago. I found some of them, but they seemed very difficult and I slowly digested them.
I encountered a problem when testing the CAN communication isolation chip a few days ago. I hope you can give me some advice.
The question is quite long, so I wrote it in the Word attachment, and also attached the chip specification. I think it might be caused by the incorrect input level range of CAN communication.
