I use cg's 2812, but the program cannot be written successfully. It always shows "unload failed". But I have never locked the chip. It is a new chip. Has anyone done this before? Can you tell me the d...
For controlling stepper motors, the most important control parameters are the number and frequency of pulses. The combination of the two can achieve the required motor acceleration and deceleration cu...
In fact, it is the same as the single value principle, that is, it is subtracted by one when getting and increased by one when releasing.
If there is only one single value, just GET it.
Then, followin...
