Is there any IC or circuit that can realize the self-test signal generator in circuit design? It means that a board is connected to another board, and there is a problem, but we don’t know which board...
I found some minor bugs in the V2 firmware. I couldn't use main.py to port the official mouse example. Later, I added LED debugging and found a problem with the while statement. Commenting out the whi...
I use an 8M crystal oscillator to read serial flash - AT45DB081, but the speed still does not meet my requirements (written in C language). I want to overclock, but I don't know how much the 430 can b...
Mobile C++ Phone Shutdown Processing Event I want to respond to an event when the phone is turned off, and then do some other processing in this event. But now I can't get the phone shutdown event. Fo...
After studying ADS1115 for a while, I finally got it done. In fact, the operation is quite simple. It is mainly divided into three parts. This example simulates IIC operation. . . . In fact, it is mai...
