I have basically never drawn PCBs, because I have always wanted to do "pure software" ("pure software" for microcontrollers), but unfortunately reality cruelly declares that this is unlikely. So I sta
The blue one is the PWM output by the microcontroller, and the yellow one is the PWM output by 2110. Why does the PWM output by 2110 have a slightly high level when the microcontroller is at a low lev
Turn on the ADC to detect the analog signal, and after getting the corresponding digital data, pass it to the DAC output. It may be that the crystal oscillator can't keep up. It's only 12M, and it won
The data in China's car driving recorder should include two parts, one is the real-time data of the car (storing the data before and after the car accident), and the other is the historical data of th
