The advanced timer (TIMER0) can be seen as a three-phase PWM multiplexed on 6 channels. It has complementary PWM outputs with programmable dead-time generation. It can also be used as a complete general timer. The 4 independent channels can be used for input capture, output compare, PWM ...

What i've been trying to do is using the HardwareTimer class to setup a PWM output for a buzzer and used a specific timer channel to do so. But the first problem I encountered was that the timer or channel was not disabled when the Pause() function is called. Looking at the code I...

brightness, I didn’t use the PCF8574 to be the only control for it. I use the control line only to pull the cathode of the LED to ground. The anode of the LED is connected to a jumper pin, so I implemented a circuit (Q106) to drive this terminal from a PWM output of the ...
