Regarding the problem of SPI host sending data, the 51 single-chip microcomputer I use does not have its own SPI interface, so I simulate SPI and transmit data bit by bit. Originally, the high bit is ...
It was working fine before, but after downloading several programs, it suddenly stopped working, and even the chip could not be detected. I only used the resources on the board, and there was no exter...
74ls165 is parallel port input and serial port output. But I can't figure out where to use it in 51 to achieve what function. :Sad:
Please give me some advice......
I want to use a single-chip microcomputer to realize the line control of headphones. The single-chip microcomputer detects the button being pressed and sends the corresponding signal to the MIC to be ...
