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 ...

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 ...

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 “Product How-To” article focuses how to use a certain product in an embedded system and is written by a company representative. Light-emitting diodes (LEDs) have emerged in recent years as ...

Sometimes you need to generate a pulse-width-modulation (PWM) signal for your circuit to simulate a certain behavior. The technique described here generates a simple programmable PWM signal for less ...

We love little tricks like this. Suppose that you want to generate an IR remote’s signal. It’s easy, because most of the codes are known. But it can be slightly harder because most IR remotes and ...
