I plan to use two 18v25cs on Arduino UNO to control two motors. To enable drive, brake and coast, I would need to connect to four PWM output on Arduino.
I plan to use pins 9/10 and pins 3/11 which have the same frequency of 500Hz. However, the timer for pins9/10 is 16bit and has higher resolution than pin3/11. Would that make the motors operate differently??
I also consider to use pins 5/6 and pins 3/11 because they both have the same timer of 8 bits. but the frequency for pins 5/6 is 1000Hz. I could change the frequency of pins 3/11 to 1000Hz but i would like to keep programming the low level stuff to the minimum.
Do you have any recommendations?
