The 3.3V microcontroller used here requires a logic level shifter to boost the PWM signal up to 5V for the fan. I use the 74AHCT125 to perform the logic level conversion, using pin #40, VBUS, to ...

How many pins can I PWM at one time with the MSP430G2253 ... You will see that there are 2 TimerA peripherals with 3 capture/compare channels each with all of these signals being routed out to pins on ...

FAN_PIN = ??? ### RaspberryPi GPIO PI used to drive PWM pin ... C => 50% PWM FAN speed ( FAN spins at 1/2 throttle ) ### 60°C - 69°C => 75% PWM FAN speed ( FAN spins at 3/4 throttle ) ### 70°C - 79°C ...

I would like to understand better the PWM ... pin is used for waveform output) or should it be connected to PWM device such as TWL4030 ? About the TWL4030 - it is an integrated power-management/audio ...
