One way around the problem of getting a fast response from a microcontroller is to move the problem away from the processor. In the case of the Pi's processor there are some built-in devices that can ...

The micro:bit framework attempts to provide PWM in easy-to-use forms. It provides functions which target the two main uses of PWM – D-to-A conversion and controlling servo motors. More about both ...

I recently published a Design Idea (DI) showing some very simple circuits for PWM programming of standard regulator chips, both linear and switching, “Revisited: Three discretes suffice to interface ...

I’ve recently published Design Ideas (DIs) showing circuits for linear PWM programming of standard bucking-type regulators in applications requiring an output span that can swing below the regulator’s ...
