LPC17xx/40xx Comparator example

Detailed Description

Example description
The CMP example demonstrates using the analog comparator.

This example configures the positive voltage input as the voltage found on PIN0.25, which is trimmed through the potentiometer. Adjust the POT up and down to adjust the voltage into the analog comparator. When the voltage crosses the negative voltage input, a CMP IRQ is fired. Based on which side of the voltage is in reference to the bandgap, the LED state will change.

Special connection requirements
Connect P0.25 (J5.24) to P1.7 (J5.29) to input the comparator 0
