Oct 1, 2020 · A PWM output will give you a PWM signal. It's operating frequency will be limited by the clock frequency and the divider options that the microcontroller features. If one of the …

May 17, 2018 · Instead of PWM, you could output the most significant bit of all duty cycle values to the respective pins, simultaneously. Then you'd output the second-to-most-significant bits, …

Apr 26, 2012 · The idea is to have micro-controller or FPGA output PWM signal (5V or 3.3V while PWM is 100%), and then use a transistor to power ventilator that needs 12V to run. I know that …

I am powering P-MOSFET with a simple 1-BJT-transistor-"driver". Output is filtered with an 22uH inductor + 330uF cap. Surely I have kickback diode in place. The problem I have is while I …

Oct 5, 2017 · If you're asking whether or not there's a difference between the PWM functionality of a microcontroller vs. "bit banging" a GPIO output manually to create PWM please emphasis on …

The PWM configuration was all pretty much taken care of by the micro. Capping the output duty cycle would just be a matter of signal filtering, which you can do in the micro. I would say IMO …

Here is some references of MCUs with high PWM outputs (> 12) Freescale Kinetis K10 @ 120 MHz series (ARM-Based) : 2x8ch + 2x2ch = 20 PWM channels; A small number of dsPIC33 …

Adding PWM to control the voltage with this scheme makes the switching frequency six times the output frequency. The switching frequency is usually selected to be much more than six times …

It did not work using TIM_CHANNEL_ALL in the second call, but using TIM_CHANNEL1 instead worked (it started actual PWM output on the output pin). Similarly for the other 3 channels, …

Apr 3, 2015 · When PWM is converted to an actual analog signal, that's always done with a low-pass filter of some sort. Here's are some examples: So called "poor man's DAC", which …
