Re: Speed Sensor

You can use onboard PWMs or software/timer generated PWMs to create a make shift ADC. Simply feed the output to a small capacitor connected to an analog input with a resister between the capacitor and the analog input that leads to ground.

Take a look at this: http://www.piclist.com/techref/sceni...pwm/pwm_vp.htm
