I have a controller which has predefined PWM frequency of 150 Hz. This output is used to control a motor. However, I want to use another PWM frequency, but I can not change the PWM frequency on my controller via the control software. Only the duty cycle is changable.
What is an easy and cheap way to be able to use a different PWM frequency?
My motor is a 9V DC motor.
My controller is called TXT and uses this firmware.
