Hi

I have an Arguino Dueminalove which has got a capacitive touch circuit attached via input 2.

The touch circuit is shown here:

Instead of the LED I have a wire going to input 2 on the Dueminalove. Now using the code below, I got it to turn on and off an LED connected to pin 13:

PHP Formatted Code
// constants won't change. They're used here to 

// set pin numbers

const int buttonPin = 2;    //  the number of the pushbutton pin

const int ledPin =  13;     //  the number of the LED pin

// variables will change

int buttonState = 0;       //   variable for reading the pushbutton status

void setup() {

//   initialize the LED pin as an output

  pinMode(ledPin, OUTPUT);      

 //  initialize the pushbutton pin as an input

  pinMode(buttonPin, INPUT);     

}

void loop(){

    digitalWrite(buttonPin, HIGH);

 //  read the state of the pushbutton value

  buttonState = digitalRead(buttonPin);

 //  check if the pushbutton is pressed.

//   if it is, the buttonState is HIGH

  if (buttonState == HIGH) {     

//     turn LED on    

    digitalWrite(ledPin, HIGH);  

  } 

  else {

//     turn LED off

    digitalWrite(ledPin, LOW); 

  }

}

All fine... now I have my Peggy and I want to use the same touch input on that. I tried making a circle of LEDs to illuminate and integrate it into the code above but I've had no luck. I'm having concerns about how Peggy knows which pin 2 is based on the code I wrote for the Duemanilove...

Anyway here's the code I wrote, it doesn't appear to work but it might help:

PHP Formatted Code
// constants won't change. They're used here to 

// set pin numbers:

const int buttonPin = 2;     // the number of the pushbutton pin

// variables will change:

int buttonState = 0;         // variable for reading the pushbutton status

#include <stdlib.h> 

#include <avr/pgmspace.h> 

Peggy2 frame1;     // Make a frame buffer object, called frame1

void setup() {

  // (Only needed once, even if you've got lots of frames.)

  unsigned short y = 0;     

  while (y < 25) {

    frame1.WriteRow( y, pgm_read_dword(&data1[y]));  

    y++;

  }

}

void loop(){

    digitalWrite(buttonPin, HIGH);

  // read the state of the pushbutton value:

  }

    // turn LED off:

}

I have made progress, I now have the image displayed constantly and then when i press the wire on the capacitive touch sensor it dissappears ( the reverse of what i wanted ).

The Wire from my circuit is going to PB1 (Pin 9)

  }

}

Sorted it, changed the if value to LOW and increased the frame buffer to 10000.

One more thing now, the LEDS illuminated are quite dim and could do with being brighter... i'm on an AC power supply and i've maxed out the trim pots yet I know they can go brighter as when I upload via Arduino a row often comes on and flashes randomly...

How can I make them brighter? Also, they're arranged every other LED hole, almost like a chequer board.

I'm glad that you got the touch sensor working-- neat hack!

You need to back up and understand how the Peggy 2 works. Please read through this post for the gory details.

Cheers Windell, that's clarified a lot...

Sounds like my best solution would be software wise - only running the rows I need to be on. As you can see in my code I only run 9 rows for the example shown, I take it I need to add some code along the lines of:

Show_row(x);

I'm not entirely sure where I place this so I'll go about having a play around, I presume it's in the loop section alongside the:

frame1.RefreshAll(10); //Draw frame buffer 10 times

I'd just change this to only show a certain amount of rows?

By: Windell (offline) on Wednesday, April 21 2010 @ 12:51 PM PDT

Windell

Other factors aside, you can probably also switch out the resistor with a 25 or 30 mA setpoint-- between that and drawing only 9 rows, you should be able to make the display about 3.5 X brighter.

A couple of possible approaches for the programming:

1) Modify the RefreshAll function in the Peggy2 library. It's okay-- you can always download a copy version if you break it. Make sure that you've got the latest version of the Arduino IDE (0018).

2) Add a new function to turn on a single row-- which you would call like frame1.ShowRow(10) -- to the library. You can add that next to the RefreshAll function in the library .cpp file, but note that you'll also need to add a prototype for it in the .h file.

3) Add the code to do what you want directly in the Arduino program, without touching the library.

Cheers for the help Windell, I think I'd rather stick to the Arduino program rather than modifying the library - only because upon opening the Peggy2.h and Peggy2.cpp I'm in a little over my head, I'm open to any help or advice you can provide though.

Back to the duino code, I'm just trying to figure out how to add it:

PHP Formatted Code
void loop() {

  touchSensor = digitalRead(touchSensorPin);  // read the touch sensor

  if (touchSensor == LOW) {                  // if the touch sensor is sending 5 volts

        frame1.RefreshAll(5000); //Draw frame buffer 10 times 

  }

}

I can't just replace the RefreshAll, I get an error:

PHP Formatted Code
 In function 'void loop()':

error: 'class Peggy2' has no member named 'ShowRow'

I presume I need to add some stuff in the setup?

By: Windell (offline) on Wednesday, April 21 2010 @ 01:53 PM PDT

Windell

There is not an existing function "ShowRow," and the error you get is reminding you of that.

I could put this in the library (a new version) but I won't have a chance to do that today.

I can give you some code to try, by adding to the library, if you're willing.

I'd be willing to give it a go by all means Windell, failing that an updated library would be great!

Thanks once again!

Okay-- totally untested here --

Part 1: Add the following chunk to Peggy2.cpp, right after the end of the RefreshAll(){ ...} function.

PHP Formatted Code
void Peggy2::ShowRow(uint8_t rowNum)

{  

  union mix_t {

    unsigned long atemp;

    unsigned char c[4];

  } mix;

if (rowNum < 25){

      mix.atemp = buffer[rowNum];

      SPI_TX(mix.c[3]);

      SPI_TX(mix.c[2]);

      SPI_TX(mix.c[1]);

      PORTD = 0;  // Turn displays off

      SPI_TX(mix.c[0]);

      PORTB |= 2U;    //Latch Pulse

      PORTB &= 253U;

       rowNum++;

          if (rowNum < 16)

        PORTD = rowNum;

      else

        PORTD = (rowNum - 15) << 4;

 }

 else

 {

  SPI_TX(0);

  SPI_TX(0);

  SPI_TX(0);

  SPI_TX(0);

  PORTD = 0;  // Turn displays off

  PORTB |= 2;    //Latch Pulse

  PORTB &= 253;

 }

}

Part 2: Add the following chunk to Peggy2.h, right after the end of the RefreshAll(){ ...} function.

PHP Formatted Code
    // Turn on a single row, with full (non-multiplexed) intensity.

        // Use rowNum value of 25 to turn off the row.

        // Can be used for limited or manual multiplexing.

        void ShowRow(uint8_t rowNum);

Right, that appears to be working Windell, but I couldn't use the code generated from the Peggy Draw to create the circle I wanted, instead I've used GetPoint and done it manually:

PHP Formatted Code

#include <Peggy2.h>

#include <math.h>

#include <stdlib.h> 

#include <avr/pgmspace.h> 

Peggy2 frame1;     // Make a frame buffer object, called frame1 

void setup() {

    frame1.HardwareInit();   // Call this once to init the hardware. 

}

void loop() {

        frame1.ShowRow(24);

frame1.SetPoint(6,24); 

frame1.SetPoint(8,24);

frame1.SetPoint(10,24);

frame1.SetPoint(12,24);

        frame1.ShowRow(23);

frame1.SetPoint(5,23); 

frame1.SetPoint(7,23);

frame1.SetPoint(9,23);

frame1.SetPoint(11,23);

frame1.SetPoint(13,23);

        frame1.ShowRow(22);

frame1.SetPoint(4,22); 

frame1.SetPoint(6,22); 

frame1.SetPoint(8,22);

frame1.SetPoint(10,22);

frame1.SetPoint(12,22);

frame1.SetPoint(14,22); 

        frame1.ShowRow(21);

frame1.SetPoint(3,21); 

frame1.SetPoint(5,21); 

frame1.SetPoint(7,21);

frame1.SetPoint(9,21);

frame1.SetPoint(11,21);

frame1.SetPoint(13,21);

frame1.SetPoint(15,21);

        frame1.ShowRow(20);

frame1.SetPoint(4,20); 

frame1.SetPoint(6,20); 

frame1.SetPoint(8,20);

frame1.SetPoint(10,20);

frame1.SetPoint(12,20);

frame1.SetPoint(14,20); 

        frame1.ShowRow(19);

frame1.SetPoint(3,19); 

frame1.SetPoint(5,19); 

frame1.SetPoint(7,19);

frame1.SetPoint(9,19);

frame1.SetPoint(11,19);

frame1.SetPoint(13,19);

frame1.SetPoint(15,19);

        frame1.ShowRow(18);

frame1.SetPoint(4,18); 

frame1.SetPoint(6,18); 

frame1.SetPoint(8,18);

frame1.SetPoint(10,18);

frame1.SetPoint(12,18);

frame1.SetPoint(14,18); 

        frame1.ShowRow(17);

frame1.SetPoint(3,17); 

frame1.SetPoint(5,17); 

frame1.SetPoint(7,17);

frame1.SetPoint(9,17);

frame1.SetPoint(11,17);

frame1.SetPoint(13,17);

frame1.SetPoint(15,17);

        frame1.ShowRow(16);

frame1.SetPoint(4,16); 

frame1.SetPoint(6,16); 

frame1.SetPoint(8,16);

frame1.SetPoint(10,16);

frame1.SetPoint(12,16);

frame1.SetPoint(14,16); 

        frame1.ShowRow(15);

frame1.SetPoint(3,15); 

frame1.SetPoint(5,15); 

frame1.SetPoint(7,15);

frame1.SetPoint(9,15);

frame1.SetPoint(11,15);

frame1.SetPoint(13,15);

frame1.SetPoint(15,15);

       frame1.ShowRow(14);

frame1.SetPoint(4,14); 

frame1.SetPoint(6,14); 

frame1.SetPoint(8,14);

frame1.SetPoint(10,14);

frame1.SetPoint(12,14);

frame1.SetPoint(14,14);   

        frame1.ShowRow(13);

frame1.SetPoint(5,13); 

frame1.SetPoint(7,13);

frame1.SetPoint(9,13);

frame1.SetPoint(11,13);

frame1.SetPoint(13,13);

       frame1.ShowRow(12);

frame1.SetPoint(6,12); 

frame1.SetPoint(8,12);

frame1.SetPoint(10,12);

frame1.SetPoint(12,12);

}

Now that works, they're notably brighter:

The problem comes when I try to integrate it into the code, the RefreshAll allowed me to specify how many times it would do it e.g. 5000 - 5 seconds but now I can't do that and when I place it in the code as shown below:

PHP Formatted Code

int touchSensorPin = 9;   // this is the digital input pin for the touch sensor

int touchSensor = 0;      // this is a variable to hold the state of the touch sensor

#include <Peggy2.h>

#include <math.h>

#include <stdlib.h> 

#include <avr/pgmspace.h> 

Peggy2 frame1;     // Make a frame buffer object, called frame1 

void setup() {

    frame1.HardwareInit();   // Call this once to init the hardware. 

  // (Only needed once, even if you've got lots of frames.)

    pinMode(touchSensorPin, INPUT);  // set the touch sensor pin as a digital input

}

void loop() {

  touchSensor = digitalRead(touchSensorPin);  // read the touch sensor

  if (touchSensor == LOW) {                  // if the touch sensor is sending 5 volts

       frame1.ShowRow(24);

frame1.SetPoint(6,24); 

frame1.SetPoint(8,24);

frame1.SetPoint(10,24);

frame1.SetPoint(12,24);

        frame1.ShowRow(23);

frame1.SetPoint(5,23); 

frame1.SetPoint(7,23);

frame1.SetPoint(9,23);

frame1.SetPoint(11,23);

frame1.SetPoint(13,23);

        frame1.ShowRow(22);

frame1.SetPoint(4,22); 

frame1.SetPoint(6,22); 

frame1.SetPoint(8,22);

frame1.SetPoint(10,22);

frame1.SetPoint(12,22);

frame1.SetPoint(14,22); 

        frame1.ShowRow(21);

frame1.SetPoint(3,21); 

frame1.SetPoint(5,21); 

frame1.SetPoint(7,21);

frame1.SetPoint(9,21);

frame1.SetPoint(11,21);

frame1.SetPoint(13,21);

frame1.SetPoint(15,21);

        frame1.ShowRow(20);

frame1.SetPoint(4,20); 

frame1.SetPoint(6,20); 

frame1.SetPoint(8,20);

frame1.SetPoint(10,20);

frame1.SetPoint(15,19);

        frame1.ShowRow(18);

frame1.SetPoint(4,18); 

frame1.SetPoint(6,18); 

frame1.SetPoint(8,18);

frame1.SetPoint(10,18);

frame1.SetPoint(12,18);

frame1.SetPoint(14,18); 

        frame1.ShowRow(17);

frame1.SetPoint(9,17);

        frame1.ShowRow(16);

frame1.SetPoint(4,16); 

frame1.SetPoint(6,16); 

frame1.SetPoint(8,16);

frame1.SetPoint(10,16);

frame1.SetPoint(12,16);

frame1.SetPoint(14,16); 

        frame1.ShowRow(15);

frame1.SetPoint(3,15); 

frame1.SetPoint(5,15); 

frame1.SetPoint(7,15);

frame1.SetPoint(9,15);

frame1.SetPoint(11,15);

frame1.SetPoint(13,15);

frame1.SetPoint(15,15);

       frame1.ShowRow(14);

frame1.SetPoint(4,14); 

frame1.SetPoint(6,14); 

frame1.SetPoint(8,14);

frame1.SetPoint(10,14);

frame1.SetPoint(12,14);

frame1.SetPoint(14,14);   

        frame1.ShowRow(13);

frame1.SetPoint(5,13); 

frame1.SetPoint(7,13);

frame1.SetPoint(9,13);

frame1.SetPoint(11,13);

frame1.SetPoint(13,13);

       frame1.ShowRow(12);

frame1.SetPoint(6,12); 

frame1.SetPoint(8,12);

frame1.SetPoint(10,12);

frame1.SetPoint(12,12);

  }

}

It will quickly cycle through it then get stuck on the last ShowRow(12) and stay there...

Any idea of a workaround?

Sorted it...

Had to include a var as a timer:

PHP Formatted Code
  if (touchSensor == LOW) {                  // if the touch sensor is sending 5 volts

var = 0;

while(var < 5000){

All the illumination with show rows etc.

and then at the end:

PHP Formatted Code
  var++;

}

Interesetingly though I couldn't get it to turn off without putting this at the end, after the if statement:

PHP Formatted Code
}


        frame1.ShowRow(0);

That seemed to Con it into showing that row constantly whilst the touch sensor wasn't being touched and as I had not called on anything in the row it remained off. I thought frame1.Clear() would have done the trick but it didnt, it caused it to hang on the final row

Windell

You may need to re-read that article Smile

The "frame" that you've declared stores on/off data for 625 locations. Calling Clear() will only erase that frame buffer-- it won't actually clear anything from the screen. Again, you should call frame1.ShowRow(25) to turn off the LEDs.

Likewise, scanning through those rows as fast as possible is not necessary-- I'd say to something like this:

loop (){

frame1.ShowRow(25); // turn off LEDs before we start changing the array

frame1.SetPoint(6,24);
frame1.SetPoint(8,24);
... (all your setpoints/changes go here!)
frame1.SetPoint(10,22);

byte j = 12;
while (j < 25){
frame1.ShowRow(j);
delay(2); // delays by 2 ms!

j++;

}

Right, I've got it working so thanks Windell for the code!

Now, I'm trying to expand my range of touch inputs, I want to have four eventually but I'll start out with two, they're currently all wires connected to PB1-PB4.

The ones I'm trying to use are PB1 and 2 e.g. Pin 9 and 10 so I've added a second set of values to my code as you can see, the var's etc. have all had name changes and the frame buffer has been renamed for the second LED image but it doesn't work, even the original doesn't work:

WORKING CODE WITH 1 INPUT

PHP Formatted Code

int touchSensorPin = 9;   // this is the digital input pin for the touch sensor

int touchSensor = 0;      // this is a variable to hold the state of the touch sensor

int var = 0;

#include <Peggy2.h>

#include <math.h>

#include <stdlib.h> 

#include <avr/pgmspace.h> 

Peggy2 frame1;     // Make a frame buffer object, called frame1 

void setup() {

    frame1.HardwareInit();   // Call this once to init the hardware. 

  // (Only needed once, even if you've got lots of frames.)

    pinMode(touchSensorPin, INPUT);  // set the touch sensor pin as a digital input

}

void loop() {

frame1.ShowRow(25); // turn off LEDs before we start changing the array

  touchSensor = digitalRead(touchSensorPin);  // read the touch sensor

  if (touchSensor == LOW) {                  // if the touch sensor is sending 5 volts

var = 0;

while(var < 500){

frame1.SetPoint(6,24); 

frame1.SetPoint(8,24);

frame1.SetPoint(10,24);

frame1.SetPoint(12,24);

frame1.SetPoint(5,23); 

frame1.SetPoint(7,23);

frame1.SetPoint(9,23);

frame1.SetPoint(11,23);

Try debugging the sensor code separately from the display code.

You may find it easier to use a single frame and change its contents based on the sensor data.
