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 ...

Back in October I was pondering the creation of accurate micro-voltages from a microcontroller. What makes this so difficult is the voltage offset created by current in the microcontroller bond wire, ...

If your Arduino runs out of I/O lines, you can always add one of the several I/O expander chips that takes a serial interface to set its several pins. Or perhaps you could buy something like an ...
