Communicating POT Value to Amulet Display

Arduino
Easiest way to add an LCD display to your Arduino projects
/* Arduino sketch to read POT value on analog pin 0 and assigning the value to AmuletWords[0].
*  To make Amulet request the proper variable, place this command in a view widget's (bargraph, numericField, etc) Href in GEmstudio:
*  Amulet:uart1.word(0).value()
*/


#include <AmuletLCD.h>

#define VDP_SIZE 32
//Virtual Dual Port memory used for communicating with Amulet Display 
uint16_t AmuletWords[VDP_SIZE]  = {0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0};

AmuletLCD myModule;

void setup() {
  //start communication with Amulet Display at default baud
  myModule.begin(115200);
  //register our local buffer with Amulet state machine
  myModule.setWordPointer(AmuletWords,VDP_SIZE);
}

void loop() {
  //store analog data in local buffer and wait for Amulet to poll that buffer.
  AmuletWords[0] = analogRead(0);
  delay(100);
}

//This method automatically gets called if there is any serial data available

void serialEvent() {
    myModule.serialEvent(); 
}
