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...
I have configured it to SCI_A download mode and used the official routine, but it just can't connect. Sector problems occur when using my own program...

From the PIC16F946 datasheet, we know that there are two ways to write values to the LCD for display:
1. Directly write the value to LCDDATA1~LCDDATA23
2. Use disconnect t...[Details]
1. Introduction
At present, most lighting equipment still uses traditional energy for lighting. Making full use of solar energy as the energy supply for lighting equipment is of great si...[Details]
Vertical cavity surface emitting lasers (VCSELs) are gradually replacing traditional edge emitting lasers, especially in low bandwidth and short-distance communication systems where cost factors ar...[Details]
Contact resistance
is the resistance to current flow through a closed pair of contacts. This type of measurement is performed on devices such as connectors,
