Hello, I am trying to use Raspberry Pi 2's PWM pin to control an LED driver. I am using the wiringpi2 library. The driver needs a PWM frequency of 100Hz to 1KHz. Since I don't have an oscilloscope I cannot see which frequency PWM pin Raspberry Pi 2 is running.
So can anybody tell me what the hardware PWM frequency is on Raspberry Pi 2 by default? And if I can adjust it?
