Hi. I'm using a MC9S08AW60 MCU. Below is part of the code for controlling the speed of a DC motor using PWM. The motor is able to rotate but I'm not sure how to control the speed.
Can anyone advice me which parts of the above code controls the speed? This code is not written by me, so I'm quite clueless on this. Below is the link to the MCU datasheet. The PWM topic is at chapter 10. Thx
