Use 51 to detect the state of 20 signals as 0 or 1, and transmit them to PC through serial port. I use 3 373 to latch the signal first, then select each 373 to input to an I/O port, and use these 8 si...
Performing 256-point FFT on the STM32F10XX series IC, the effect is not bad, the waveform is as expected, and basically no major abnormalities are found.Input signal: X="1"+sin(2*pi*fo*t)Signal freque...
Everyone says that learning microcontrollers should start with 51, and 8-bit ones are easy to learn! Indeed, it is easy to get started, but electronics is not my major, and I didn’t have much contact ...
UHF and HF are both general technology categories, but each category has independent supporting protocols. HF is more consistent in the 13.56MHz frequency band, although there are many internation...[Details]
