When multiple variables use the same timer (the time the variable changes is an integer multiple of the timer time), how to control the timer to start and stop.I now think of three methods:1. The time...
I currently need a frequency multiplier for a project. The required input range is: within a few MHZ-1GHZ. It would be best if the frequency value and the multiplier number can be set. I hope an exper...
The circuit principle is as follows: 6N137 isolates a PWM signal, the frequency is 2-10K, and now there is a very annoying "step", about 2 microseconds, the voltage is around 5V. I don't know why this...
Two months ago, I used VET6's SPI1 to operate a font chip, but the result was very unstable. Finally, I used IO simulation, which was OK; but SPI2 operated M25P64, and it worked.Now I use C8T6's SPI t...
