GITHUB REPO: https://github.com/sparkfun/SparkFun_MicroMod_Main_Board_Single
DEVELOPMENT ENVIRONMENT SPECIFICS:
Firmware developed using Arduino IDE v1.8.12
========== DESCRIPTION==========
This example code toggles the Function Board's AP2112 3.3V voltage
regulator's enable pin. The Function Boards built-in power LED should blink.
This example is based on Arduino's built-in Blink Example:
https://www.arduino.cc/en/Tutorial/BuiltInExamples/Blink
Note that this example code uses the MicroMod Main Board - Single. The MicroMod
Main Board - Double routes the PWR_EN# pins slightly different for the
two function boards.
========== HARDWARE CONNECTIONS ==========
MicroMod Artemis Processor Board => MicroMod Main Board - Single => Function Board

/*Define the power enable pins for the processor board with either SDIO_DATA2 or A1.
Depending on the processor board, the Arduino pin may be different.
Note: Certain Processor Boards like the Artemis have SDIO_Data2 and A1 available
to control the Function Board's voltage regulator. SAMD51, ESP32, and STM32
Processor Board pins do not have SDIO Data 2, so users will need to reference
the Processor Pin A1. Below are a few examples. */
//ARTEMIS
#define PWR_EN0 4 //Function Board 0's "PWR_EN0" pin <= MicroMod SDIO_DATA2 => Artemis Process
or Board (D4)
//Alternative option that does the same thing. Make sure to just choose one for PWR_EN0
//#define PWR_EN0 35 //Function Board 0's "PWR_EN0" pin <= MicroMod A1 => Artemis Processor Bo
ard (A35)
//TEENSY
//#define PWR_EN0 15 //Function Board 0's "PWR_EN0" pin <= MicroMod A1 => Teensy Processor Boa
