It’s a minuscule 2-channel PWM generator module with variable frequency 1Hz to 150kHz and duty cycle 0% to 100%. ... PWM signal output (x2) rendered by the dual channel PWM module, and captured by my ...

[Herp] just shared a nice 1MHz Arbitrary Waveform Generator (right click -> translate to English as google translation links don’t work) with a well designed user interface. His pla… ...

The final PWM generator looks great. ... If I read his schematics and code correctly, he is sending a 500 Hz PWM signal of between 0% to 100% duty cycle through a transistor.

I recently tried this combination 20 Msample/s simultaneous sampling oscilloscope, function generator, PWM signal generator, and digital I/O module. While it works, getting it to work is more tedious ...

A pulse generator or a microcontroller can provide the PWM input, which can vary in frequency and duty cycle. The circuit shown can accept signals with 1% to 99% duty cycles.

The circuit's output is the PWM signal used by the backlight inverter to achieve digital dimming. V CC is the inverter input (e.g., 12 V), and is also used as the supply for the PWM signal generator.
