I've been studying hardware recently, and I found that there are many organizations in Shanghai that study software, such as SHLUG and GTUG. They often hold events and have some very interesting lectu...
I wrote a program for LCD12864 using PIC24 for three days, but it didn't work. I modified the program for 51 and M430, but it didn't work. I couldn't debug it for three days, and I was very depressed....
The idea is this: when the program is running, when the function needs to display pictures, it reads the picture files from the disk and generates a playlist, then displays them in sequence from the p...
