Once the timer shows up in the graphical display, you can adjust some sliders to get the exact PWM duty cycle you want. Of course, you can also skip the PWM code and just use the timer interrupts ...

To keep things simple, for now, you just send an 8-bit hex number to set the PWM output duty cycle. For example, if you send an uppercase A (65 decimal or 41 hex), the output will be at 65/256 or ...

As explained earlier, a low resolution PWM signal is quantized in time, i.e. limited to switching only at certain points in time. When limit-cycling occurs, the duty cycle bounces between distinct ...

Unlike pure resistive loads for DC motors, the resistance, inductance and back EMF on the rotor windings are deciding factors in optimizing PWM frequency and duty cycle. Linear vs. PWM Power ...

Several years ago I wrote an article in Design Ideas called “Double µC’s PWM frequency & resolution” where I mentioned how one can decrease the output ripple of a PWM-based DAC using two PWM signals ...

The drive signal for the RF carrier amplifier is a square wave, while the drive signal for the modulator is a rectangular wave with the width varying in accordance with the PWM duty cycle. The ...

The term “fraction” implies that this circuit performs division, as the output PWM duty cycle is V In /V Ref. 1. This basic linearized PWM generator, without an external feedback mechanism ...

which controls fan speed according to the PWM duty cycle, by toggling the fan-motor current off and on. The circuit of Fig. 1 also controls the fan with a 100-Hz PWM signal, generated by the open ...
