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 ...

除了使用线性方法保持关键组件恒温，基于PWM的方法更易于控制温度... 在这一系列设计实例文章的第一部分，我们探讨了使用线性方法来保持关键组件恒温的简单方法。在第二部分，我们将继续探索基于脉冲宽度调制(PWM)的方法，这种方法更易于控制，因而 ...

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 ...
