Can anyone help use the Frappuccino library to communicate through Arduino?

in Contributed Library Questions • 5 months ago

Hi all, I am working on a project that involves using an Arduino with the "standard firmata" to receive signals from a joystick. But I also have a standard 16x2 LCD attached to the Arduino, and I want to be able to display text on the LCD while the user plays the game.

I discovered the "Frappuccino" library which seems to offer a way to do this, but I can't figure out how the library works. The Frappuccino example for using a LCD looks like this:

import muvium.processing.*;
import muvium.processing.arduino.LiquidCrystal;
import muvium.sim.virtualbreadboard.ICEShield;
public class HelloWorldApp extends V18OBoard{
LiquidCrystal lcd;
/**
Static Pins are configured in the configureDevice pre-process
*/
public void configurePins(){
LiquidCrystal.configurePins( new int[]{ 9, 8, 5, 4, 3, 2 } );
ICEShield.configurePins(0); //Use pin 0 as wait pin - using ICEShield for testing with virtual hardware
//! comment out when using with real hardware
}
public void setup() {
lcd = new LiquidCrystal();
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a message to the LCD.
lcd.print("hello, world!");
}
public void loop() {
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// print the number of seconds since reset:
lcd.print(millis()/1000);
}
}
////////////////////////////////////////////////////////////////
// MUVIUM PROCESSING TOOLKIT
////////////////////////////////////////////////////////////////
void draw(){
MuviumToolkit.program( this );
}

But this example does not actually connect to an Arduino, it does not even have the Serial library added! So I am wondering if anyone familiar with the Frappuccino library can offer me a quick explanation of how it works. Am I even using it correctly? What is the Muvium Toolkit?

Thanks in advance.

I should add that I've been trying to incorporate the Frappuccino library into code that I already have working with the Arduino firmware (for detecting inputs from buttons and the joystick);

import muvium.processing.*;
import muvium.processing.arduino.LiquidCrystal.*;
import muvium.sim.virtualbreadboard.ICEShield;
import processing.serial.*;
import cc.arduino.*;
Arduino arduino;
LiquidCrystal lcd;
color off = color(4, 79, 111);
color on = color(84, 145, 158);
void configurePins() {
LiquidCrystal.configurePins( new int[] {12, 11, 5, 4, 3, 2} );
}
void setup() {
size(470, 280);
arduino = new Arduino(this, Arduino.list()[0], 57600);
configurePins();
lcd = new LiquidCrystal();
lcd.begin(16, 2);
lcd. print("hello");
for (int i = 6; i <= 9; i++)
arduino.pinMode(i, Arduino.INPUT);
}
void draw() {
background(off);
stroke(on);
for (int i = 0; i <= 13; i++) {
if (arduino.digitalRead(i) == Arduino.HIGH)
fill(on);
else
fill(off);
rect(420 - i * 30, 30, 20, 20);
}
for (int i = 0; i <= 5; i++) {
ellipse(280 + i * 30, 240, arduino.analogRead(i) / 16, arduino.analogRead(i) / 16);
}
}

And when I try to run this I get an error that says "Cannot find a class or type named 'LiquidCrystal'". But how can this be? That class exists in the Frappuccino example! I am seriously misunderstanding some Java, I think.
