In the last issue, we tested the DHT11 temperature and humidity sensor on the expansion board. This time, we are using the P98132 chip above to drive the RGB light.Let's take a look at the schematic d
Working frequency: the resonant frequency of the piezoelectric chip. The longer the wavelength, the smaller the frequency, the greater the detection distance, but the accuracy will be reduced. Sensit
How to identify the wake-up signal sent by the host when using UART to simulate LIN (the wake-up signal sent by the host is a low level signal that lasts for 250us to 5ms, and the slave uses 150us as
The wiring harness of the microcontroller can only be laid with 10 mil wires, but I want to set other ground and power lines to 50 mils, which will conflict with the microcontroller. How to set the ru
