Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required ...

Low-cost, 8-bit, single-chip microcontrollers are stingy when it comes to on-chip PWM (pulse-width-modulation) resources. The use of a PWM resource often forces a designer to sacrifice a ...

This file type includes high resolution graphics and schematics when applicable. Sometimes a design needs more DACs than the mixed-signal microcontroller has available. An easy solution is to put in a ...

I am supposed to be on other duties this week, but cannot resist pointing you in the direction of the new Raspberry Pi in-house MCU, the RP2040. Much as I want to write chapter and verse about the ...

How to set up an PIC microcontroller to deliver high-precision frequencies from 1 Hz to 4 MHz. Examples of the frequencies delivered by this microcontroller design. In timing applications, a time-base ...

Trying to create controllable low voltages – μVs – using a microcontroller is tricky. Even is only relative, rather than absolute, accuracy is required. The issue is working near oV – frequently even ...

For some projects, it’s okay to have a microcontroller twiddling it’s thumbs most of the time. When a project requires the cpu to do just one thing over and over, there’s no loss with inefficient code ...

[Hugatry] wanted to replace the adjustment pot on an LM2596 buck converter with a microprocessor-controlled voltage. The regulator IC uses a divider to generate a 1.25V reference from the output. The ...
