[Parameter Adjustment Magic] PID Parameter Adjustment Using VOFA+Upper Unit (with lower unit code)
1. What is VOFA+? Simply speaking, VOFA+ is a super serial assistant, in addition to realize the serial data sending and receiving of the general serial assistant, it can also realize the data plotting (including histogram, FFT chart), control editing, image display and other functions. Using VOFA+, it can bring convenience to our usual debugging […]
