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 ...

Those following the ProtoStack tutorials will be happy to hear that there is a new installment which explains Pulse Width Modulation. If you’ve never heard of PWM before, it’s a method of generating a ...

When I was in graduate school 10 years ago, a controls group proposed to the power-electronics center to use an advanced microcontroller in power supplies. This controller was to implement a new ...

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 ...

When designing a system, one of the most important design decisions is choosing what voltage domain(s) to use. Some voltage domains, such as 5 V, are good for noisy and harsh operating environments ...

Microchip is aiming at analogue sensors with a microcontroller that can measure signals while consuming less than 3µA while sleeping with one comparator monitoring an in-coming voltage. Called ...

Let’s say you’re working on a project, and you need a microcontroller. Which chip do you reach for? Probably the one you’re most familiar with, or at least the one whose programmer is hiding away in a ...
