This project is a part of experiments done while doing an artist in residence at Instructables. You can see the other projects here.
It can be a tricky task to debug and visualize realtime data on the Arduino board. You are usually stuck with the standard serial output, as the complexity of your Arduino code grows this makes it impossible to comprehend what is actually going on inside the board. To solve this I have created a little library that will enable you to create your own custom GUI for your Arduino projects. Watch this video to get a demonstration of a basic hello world with a potmeter and a diode:
As of now, the program has the following possibilities and features:
Custom design your interface from the Arduino board
You define which sliders, graphs and buttons you need for your interface. You do this in your Arduino sketch which means that the gui program acts as a slave to the sketch. All information is stored in your board.
Visualize and manipulate realtime data
Whether you are making an RGB light controller or a robot arm, getting a graphical feedback is crucial to understand what is going on inside the board. This enables you to understand whether it is your hardware or the code that is causing problem. Further the sliders and buttons enables you to tweak the individual parameters in realtime. This way you can see what effect different thresholds have on the interaction.
Save the parameters in the boards memory
When you have tweaked the parameters you can save them to the EEProm of the board. The parameters will be auto loaded next time you power on the board, even if the computer is not connected.
Use the same app for all your Arduino projects
I have made tons of small apps for different projects. My problem is always to find them again a year later. Because we save everything in the Arduino I only need to keep one app around the Arduino will automatically configure the app for the current project.
Prototype the interface before you turn on the soldering iron
Because you can design the gui as you like it (within reasonable limits), you can prototype the interface before you have made a physical interface. This also enables you to divide the tasks between multiple people e.g. one person is working on the hardware and another person is working on the code. When you have made the physical interface the Guino will integrate seamlessly.
Use it as a fullscreen dashboard
You can use it as a fullscreen dashboard by pressing F and pressing T toggles the visibility of the settings panel. You hereby only present your custom interface for the world around you.
Control the background color
The background color can be controlled from the Arduino this enables you to create different colors for different sketches. It can also bes used to make alerts when something is wrong. It can be green when everything is ok and red when something is wrong.
Fast and Slim
I have taken great care in making the footprint on the Arduino as small as possible - It only stores a minimum amount of data in the memory (concretely a pointer list of 100 items). This setting can be changed to lower or higher depending on the amount of gui items you intend to have in your interface. Further the system relies on the EasyTransfer library which transfers the information in binary form. Each package consists of a byte for command, a byte for item # and an integer for the value. Ideally, all your data should be normalized to a 16 bit signed integer range. This means optimal usage of the serial port when working with integers (technically we use a little extra space for a checksum).
Good for Instructables
The GUI enables you to make Instructables that only requires the core components. Extra components like potmeters etc. can be made virtually via the gui.
Limitations and future plans
Right now the app has been compiled to the Mac OSX and Windows platform. It is written in Openframeworks so It should be able to run on other platforms as well. Since the app is using the serial port you will not be able to connect other programs to the Arduino. This will be solved in a future release which will include a Open Sound Control and a Midi bridge.

Is it fine to use this function for the string to change while running the guino(while we are changing the touch configuration) without disconnecting and again connecting it ?
Here is what I did...
made 2 labels
timeLabel1 = gAddLabel("TIME: ",1);
gAddSpacer(1);
dateLabel1 = gAddLabel("DATE: ",1);
gAddSpacer(5);
and in the code somewhere made a function to call each second. You can use ds1307 and 1hz interrupt of just check if seconds and different.
// used to trigger something every second
int currSec = second();
if(currSec != prevSec)
{
// Clock ticked over another second
PrintTime();
// Update the display
prevSec = currSec;
}
void PrintTime() {
String stringOne = "TIME: ";
stringOne.concat(hour());
stringOne.concat(":");
if(minute()<=9) stringOne.concat("0");
stringOne.concat(minute());
stringOne.concat(":");
if(second()<=9) stringOne.concat("0");
stringOne.concat(second());
stringOne.toCharArray(charBuftime, sizeof(charBuftime));
String stringTwo = " ";
stringTwo.concat(Day[weekday()]);
stringTwo.concat(", ");
stringTwo.concat(Month[month()]);
stringTwo.concat(" ");
stringTwo.concat(day());
stringTwo.concat(", ");
stringTwo.concat(year());
stringTwo.toCharArray(charBufdate, sizeof(charBufdate));
gUpdateLabel(timeLabel1, charBuftime);
gUpdateLabel(dateLabel1, charBufdate);
// the following has nothing to do with time just blinks a LED each second
// if the LED is off turn it on and vice-versa:
if (ledState == LOW){
ledState = HIGH;
ledLight = 1;
}
else {
ledState = LOW;
ledLight = 0;
}
// set the LED with the ledState of the variable:
digitalWrite(ledPin, ledState);
digitalWrite(13, ledState);
}
works great... but had to put time and date on two lines since the font is not like courier but variable width and I did not like the seconds bouncing all around since a '1' is not as wide as a '8'.
I used an array to print out the date like: Monday, March 8, 2013.
If you need that part let me know.
Not sure what you mean by data logging. If you can explain that part better I will look at it. Mental block here I guess.
Also did get it to work with Mega BUT had to use Serial 3 port. That way I can upload and use GUI at same time. But my program is bigger than yours probably. Had to raise 100 item limit to 150. I had too many items to display. I guess each label or graph is an item. Mine is 5 columns wide as I am using it for automation control display.
Let me know...guy
Yes .. See my image of what I have done.
If you can not see clearly send me an email at regular email and I will send you a bigger image. Also some code. You should be able to get my email name in my personal data info. If not let me know and I will send one here for you to use.
I have made several labels and update the temps every minute and also have labels where I update events that happen with time/date stamp when they happened.
Basically you use a gLabel and then control what you want done to it in the code by calling a function with the name you set up for the label. I also am using a 2560 since my code for Guino is now at 80K.
int B_E1=0;
void setup() {
gBegin(12345);
pinMode(E1, OUTPUT);
}
void gInit() {
gAddToggle("E1",&B_E1);
}
void loop() {
guino_update();
if (B_E1)
digitalWrite(E1, HIGH);
else
digitalWrite(E1, LOW);
}
Thanks a lot
Great work on the GUI. I'm having trouble understanding how the toggle is supposed to work. The variable starts as false (as I initialized it). When the button is pressed, it goes to true. Then when pressed again, it just stays at true. I want it to go to false when pressed again.

Thanx for this awesome GUI for Arduino.
I am getting one problem......the moving label is not getting updated in real time.....I have to disconnect and then connect the GUINO for the change in the Label. Can you please assist me in this problem as soon as possible.
I am also getting the problem in changing the size of label.....only 2 and 1 can be used. I want to increase the size more than that.....
#include <Time.h>
int flexLabelId =0;
void setup(){
gBegin(34236);
setTime(19,3,0,22,3,13); // set time to noon Jan 1 2011
}
void loop(){
// **** Main update call for the guino
guino_update();
// digitalClockDisplay();
gUpdateLabel(flexLabelId, digitalClockDisplay());
delay(1000);
}
void gInit()
{
gAddSpacer(1);
flexLabelId = gAddLabel("",0);
gAddSpacer(1);
}
void digitalClockDisplay(){
// digital clock display of the time
printDigits(day());
Serial.print(".");
printDigits(month());
Serial.print(".");
Serial.print(year());
Serial.print(" ");
printDigits(hour());
Serial.print(":");
printDigits(minute());
Serial.print(":");
printDigits(second());
Serial.println();
}
void printDigits(int digits){
// utility function for clock display: prints preceding colon and leading 0
if(digits < 10)
Serial.print('0');
Serial.print(digits);
}
void gButtonPressed(int id)
{
}
void gItemUpdated(int id)
{
}
About the rest. It sounds like valid improvements. You should dig into the source and start extending the framework.
float a
int b
b = round(a*10)
thanks
Else you might have the serial monitor running in the backgrond.
Make OpenSource for OpenHardware!!!

Arduino sees my USb serial port just fine (COM4).
Is there anything I can do to make it work?
Cheers,
E.
I have had problems with one windows machine running it as well. I have not been able to pin point the cause. Maybe reinstall the ftdi drivers?
I am not sure what you mean by two devices...
