By dac0832 d/a conversion, output pulse to the dc motor, by adjusting the square wave duty ratios to adjust speed,

CodePudding user response:

High and low, is used to control the duty ratio of PWM wave, used to implement the control of motor speed,

CodePudding user response:

PWM waveform High LOw, two is duty ratio and percentage of time control current, the current speed is higher, the greater the integral charge High and LOw points, namely H account for the faster than the speed

CodePudding user response:

High low, low level, high level

First base fastened, want to fly, the first to learn to walk well

CodePudding user response:

Can ask specific questions I think is good, is better than "how electrode control",

Praise a, come on!
