I have read a lot of books and searched on Google for a long time about this function, but there is almost no usage of this function. I just know: "r_write() writes data to the file descriptor and res...
Current sampling is the basis of FOC, which includes current sensor sampling and resistor sampling. Resistor sampling is widely used due to its simple and low-cost application.
Resistance sampling inc...
