Next: Input Capture Interrupts
Up: Output Compare Interrupts
Previous: Learning Module Exercise
The purpose of this learning module was to allow the
student to build and program a simple system that
uses the output compare event to generate an analog
voltage level. The student should have learned the
following:
- How interrupts work.
- How to use the output compare interrupt to generate
a regular clock tick.
- How to use the output compare interrupt a pulse
width modulated (PWM) signal
- How to build a capacitive network that converts a
PWM signal into an analog voltage. In other words how to
use a capacitive network to build a digital to analog
converter (DAC).
- How to use a non-inverting op-amp feedback
connection to buffer the capactive DAC.
