I picked up some pulse width modulation to voltage converter modules. You’ve seen these before under a variety of names. They look amazing for the price, but there are a few little things you might ...

Chinese Digital PWM modules have come down in cost over the past few months, but picking a PWM module that will help you to do what you need actually means you have to think about a host of things, ...

Last time, I showed you a simple PWM block and an open source UART core. This time, I’ll put these parts together to create a PC PWM output peripheral. With working code (working, at least, in ...

Pulse-width modulation (PWM) peripherals have enjoyed a long association with microcontrollers and power control, starting with motor control and power conversion. For the most part, these ...

将PWM与一个小型R-2R梯形DAC相结合，既可大大减小PWM纹波，又能增加DAC分辨率，从而提高两方面的性能。本设计实例利用一个8电阻阵列和3个输出引脚对R-2R梯形DAC进行修改重构，修改的目的是将底部2R连接到PWM输出而不是将其接地。 将PWM和小型R-2R梯形DAC相结合 ...
