For example, in line 102 of my code ... try to implement this phase shift approach for different microcontrollers. Figure 1 Single and dual-PWM circuits At V out of the phase-shift DAC, two PWM ...

A circuit diagram of a driving motor using ... The motor’s inductance across its terminal is a function of the PWM frequency. For example, a catalog lists a Portescap motor’s inductance ...

Figure 2 Proposed PWM generator circuit This simple yet powerful circuit is extremely compact to integrate on a chip. For example, a 10MHz version of the circuit, including a driver for a 10pF ...

For the example circuit in Fig. 6, the PWM begins a cycle with C1 discharged to 0 V, and the cycle ends when the voltage on C1 reaches 2.5 V. The switching frequency is chosen to be 125 kHz.

This was the motivation that led him to produce the dazzling 16 RGB LED example seen in the video after the break. His setup doesn’t use expensive LED drivers, but instead utilizes 595 shift ...

for example. So how to do a nice analogue circuit? Well, here is my latest suggestion (right, modelled in LTspice, but not yet tested IRL): It is feedback-based, and forms a PWM-locked-loop.

This PWM signal can be used to apply a time indicating that something is activated, known as a duty cycle. For example, a 50% duty cycle will have the circuit load “on” for half the time.

Using two PWM pins and adding them together means it’s possible to add extra bits of resolution. This requires using different values of resistors on each pin. For example, using the same value ...

Figure2: Simplified LED-driver circuit using a PIC16HV785 microcontroller. The PIC16HV785 mixed signal microcontroller combines an 8bitmicrocontroller core with several on-chip analogue peripherals.

A simple op-amp, and pnp transistor or p-channel mosfet in the positive rail (example right), was the ... why not just use the top circuit) will excessively load the typical RC-low-pass-smoothed 3.3 ...
