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
Transformer is a device that transforms AC voltage, current and impedance. When AC current flows through the primary coil, AC magnetic flux is generated in the iron core (or magnetic core), which indu
[align=center]The main target of McQueen's car is primary and secondary school students. It is more convenient to use IPAD for programming, and the drag operation of the software is also easier to use
[size=14px]I use an external AD to sample 256 points (SIN wave) of a signal, and then do a 256-point fft operation in stm32 to calculate the amplitude and other parameters of the signal. The amplitude
