Hey, I'm looking for some ideas how to design a motor driver for a pair of DC motors. They have a input variable voltage of 0v-3.3v. When the input voltage is half (about 1.6v) the motor should stop, but if it is any greater than 1.6v it will go forward, below 1.6 it will go backward. 0v should go backward at full speed, and 3.3v should go forward at full speed. I don't know why, but I am having a real brain fart this morning and am looking for any general ideas, or what blocks i would need to do this (all i have so far is a voltage follower buffer from the power inputs)
The micro would be varying the voltage to control the direction and speed, but would I need to use comparators to do this? I found an H bridge motor driver circuit, but it looks like that is controlled by PWM http://www.societyofrobots.com/schematics_h-bridgedes.shtml
Any input is appreciated"[URL
