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 ...

STMicroelectronics has introduced a family of ARM-based microcontrollers, the STR730F Series, which addresses the emerging demand for high-performance, cost-effective and off-the-shelf 32-bit ...

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 ...

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 ...

It never fails — we post a somewhat simple project using a microcontroller and someone points out that it could have been accomplished better with a 555 timer or discrete transistors or even a couple ...

[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 ...

Hi there, and welcome to Part 3 of this soon-to-be-heralded mega-mini-series. In Part 1, we discussed the first vacuum tube diodes, moved on to their solid-state (semiconductor) descendants, and then ...
