There has always been one thing that I am unclear about. The stepper motor uses a constant current control method, which is implemented by PWM. If different voltages are supplied to the driver, will t...
The emulator is fine.I used the internal clock. Yesterday I couldn't burn it in, so I connected the XIN pin to VCC and it burned in.But it didn't work again today. Forthe 2-wire emulator, I added a 47...
The purpose of this program is to count the number of 1s in an 8-bit binary number. But when I run it, the count result is always 0. If I assign 1 to count, the result will be 1. In other words, the n...
