All the pins are named for the components used on the Locus Incepti Board.

// Push Buttons

const int rPB = 7; // Red push button connected to pin 7

const int yPB = 9; // Yellow push button connected to pin 9

const int gPB = 11; // Green push button connected to pin 11

const int bPB = 13; // Blue push button connected to pin 13

const int oPB = 24; // Onboard push button connected to pin 24

// LEDs

const int rLED = 6; // Red LED connected to pin 6

const int yLED = 8; // Yellow LED connected to pin 8

const int gLED = 10; // Green LED connected to pin 10

const int bLED = 12; // Blue LED connected to pin 12

const int oLED = 25; // Blue LED connected to pin 25

const int NeoPix = 23; // NeoPixel line connected to pin 23

// IR devices

const int IRrx = yPB; // IR receive device connected to pin 9

const int IRtx = yLED; // IR transmit device connected to pin 8

// Rotary Encoder

const int encA = 2; // Encoder A connected to pin 2

const int encB = 3; // Encoder B connected to pin 3

// Joystick

const int xJS = A0; // Joystick X axis potentiometer to pin A0

const int yJS = A1; // Joystick Y axis potentiometer to pin A1

// Buzzer

const int bzr = 22; // Buzzer connected to pin 22

// Pot & Battery Voltage

const int batV = A3; // Photo resistor connected to pin A3

const int pot = A2; // Pot connected to pin A2

// NOTE: A3 is not available on the original Pico controller

// Serial Port

const int Tx = 0; // Serial Transmit (GPIO 0)

const int Rx = 1; // Serial Receive (GPIO 1)

The pinMode() statements are also included. This pinSet() function is called from the Setup() function.

void pinSet()

{

pinMode(rLED, OUTPUT);

pinMode(yLED, OUTPUT);

pinMode(gLED, OUTPUT);

pinMode(bLED, OUTPUT);

pinMode(oLED, OUTPUT);

//pinMode(IRtx, OUTPUT);

pinMode(bzr, OUTPUT);

pinMode(rPB, INPUT_PULLUP);

pinMode(yPB, INPUT_PULLUP);

pinMode(gPB, INPUT_PULLUP);

pinMode(bPB, INPUT_PULLUP);

pinMode(oPB, INPUT_PULLUP);

//pinMode(IRrx, INPUT);

pinMode(encA, INPUT_PULLUP);

pinMode(encB, INPUT_PULLUP);

}

Finally, the count variable and the Encode() function are setup to use the rotary encoder.

volatile int count; // count holds the encoder variable.

void Encode() // Interrupt routine to manage the encoders

{ // this routine is called if encB transitions from HIGH to LOW

if (digitalRead(encB)) // Based on the state of encA we know the direction

count++;

else

count--;

}

The PicoPins3.h file is added to the project by saving it in the project directory and calling it using the include statement.

#include"PicoPins3.h"

The pinSet() function is included in the setup function as well as the Serial.begin() and Encoder Interrupt statement. Removing the comment (//) slashes will activate these statements.

void setup() {

pinSet();

//Serial.begin(115200);

//attachInterrupt(digitalPinToInterrupt(2), Encode, FALLING);

}
