FEZ Mini Pins Features
All pins on the the rear headers and UEXT can
be used as digital input/output. Some pins have
secondary features. Do not attempt to use a pin
as digital and as secondary feature
simultaneously. For example, when using Di5 as
PWM, you cannot use Di5 as a digital I/O until
you release the PWM feature (in code).
Remapping COM4
An2 and An3 are special because they can be digital, analog, or remapped to work as COM4, where An2 is
COM4 OUT and An3 is COM4 IN. Call the function below to remap COM4
Once the code above is added, you can use COM4 on An2 and An3 as shown below.
