Hello everyone, I have a chip connected to the i2c bus. I use the i2c read/write interface to write data to a certain area of the slave device, and then read it out to see if it has been written. But ...
[size=4] In some isolation, it means electrical isolation between input and output, input and ground, and output and output. The purpose of isolation is to protect the safety of the system. When there...
1. Error. No matter how good the quality of the instrument is, there is always an error between its measured value and the actual value. Therefore, "error" is the standard for measuring the accuracy o...
Is there anyone who is familiar with PCB antenna design? I want to use a PN532 chip to connect a 13.56Mhz antenna and integrate it with the PCB board, but I don’t know how to draw the antenna, and I d...
I only added a rts.lib library, and then used pow(2,4) to calculate the fourth power of 2. The result is -1 when I watch it on the emulator. What's going on? The same function is correct on the arm....
The Year of the Rabbit is here. I wish you all a salary increase as fast as a rabbit runs, red envelopes as many as a rabbit's fur, career development as high as a rabbit jumps, and a mood as happy as...
