Lab 5 – Analog Comparator
•
When enabled, the ACMP (Analog Comparator) test
configures the ACMP to compare the voltage on the
photosensor (RZ1) to the potentiometer (RV1).
•
The output of the ACMP is configured by software to be
the trigger for the TPMCH0 input capture. The demo
measures the time between each toggle of the ACMP
output.
•
Adjusting RV1 will change the amount of darkness
necessary to toggle the ACMP.
