I just followed some links and not sure where the Aardvark IDE is and see they may have made changes.

[echo] Uploading touchshiled to board…
[exec]
Hi, Hans,

Nice work on touchshield.

When running your code, I encounter problems like this on antipasto, avrdude: ser_open(): can’t set com-state for “\\.\COM4″

Any idea how to fix it? I double checked the port and board.

Thanks!

Have you tried disconnecting the Slide from the Arduino, before you program the Arduino?

On the touch side, change this section to send (Serial.print…) “mouseX” to the Arduino.

[exec] avrdude: stk500_2_ReceiveMessage(): timeout

I have no idea what the problem is. Any help would be appreciated. Thanks in advance.

thanks for reading me
I’m trying to modify your example to send mouseX to the arduino then back to the slide to be displayed as decimal. So far I get random numbers.

If you could kindly give me a hand with this I think I would be sorted for good.

Thanks!

You may need to you use a Byte Array.

char charIn = 0;
byte i = 0;
char stringIn[32] = “”;

while(Serial.available()) {
charIn = Serial.read();
stringIn[i] = charIn;
i += 1;
}

You then can covert the byte array into an integer with the following line:

int newInt = atoi(stringIn);

Let me know if that helps.

It’s the direct descendant of ladyada’s AFSoftSerial but as yet does not support the MEGA

Like Adam I could not get your demo to work.

The problem was that I used an Arduino MEGA.
When I used the Duemilanove it worked fine.

It seems AFSoftSerial doesn’t work with a MEGA.

If I comment out the following IF tests:
if(touchSerial.available())
and
if (c == ‘A’)
along with their opening & closing braces then it also works on the MEGA board.

//Arduino
#include
#define RX_PIN 3
#define TX_PIN 2
AFSoftSerial touchSerial = AFSoftSerial(RX_PIN, TX_PIN);
int redPin = 10;
int greenPin = 11;
int bluePin = 9;
int light;

void setup(){
touchSerial.begin(9600);
}
void loop(){
if(touchSerial.available()){
light = touchSerial.read();
}
if(light == 1){
analogWrite(redPin, 255);
analogWrite(greenPin, 255);
analogWrite(bluePin, 255);
}
else{
analogWrite(redPin, 0);
analogWrite(greenPin, 0);
analogWrite(bluePin, 0);
}
}

//TouchShield
void setup(){
background(255);
Serial.begin(9600);
mouseX = 0;
mouseY = 0;
fill(0);
rect(160,0,160,240);
}

void loop(){
gettouch();
if(mouseX >=160){
Serial.print(1);
delay(1000);
}
else{
Serial.print(2);
delay(1000);
}
}

if(touchSerial.read() == 1){
do whatever
}

RE: Arduino “If” Reference – http://arduino.cc/en/Reference/If

Is the reverse true for sending data from the TouchShield to the Arduino?

I am trying to get the arduino to recieve serial data sent from the TouchShield. Like

TouchShield sends:

Serial.print(1);

Arduino reads:

if(touchSerial.read() = 1){
do whatever
}

These commands do not seem to be working.

Add this to the main loop:

char charIn = 0;
byte i = 0;
char stringIn[32] = “”;

while(Serial.available()) {
charIn = Serial.read();
stringIn[i] = charIn;
i += 1;
}

if (stringIn[0])
{
background(0,0,0);
text(stringIn, 75, 75);
}

This will allow you to display strings up to 32 characters.

But after adding the software serial lines, my code is working! Thank you, I think I understand now.

The only remaining problem is how do I display what I am literally sending and not the ASCII back conversion.

i.e. I send “A” and I get 65 displayed. So if I send “Hello” how do I display “Hello”?

On the Arduino, you need to use a software serial line that uses Pins 2/3.

Add to head:

#include

#define RX_PIN 3
#define TX_PIN 2

AFSoftSerial touchSerial = AFSoftSerial(RX_PIN, TX_PIN);

Add to setup:

touchSerial.begin(9600);

Add to main loop:

touchSerial.print(randNumber);
delay(100);

May I ask how this is supposed to work? I downloaded your app and uploaded to the Arduino & TouchShield and it’s a blank screen. I checked the Serial Monitor and saw no numbers being sent. So I tried this basic code to see if serial is possible at a more basic level:

//Arduino
void setup(){
Serial.begin(9600);
}

void loop(){
Serial.print(20);
delay(1000);
}

//TouchShield
void setup(){
Serial.begin(9600);
background(0,0,0);
}

void loop(){
text(Serial.read(),80,80);
}

The results of the above code are visible ’20s’ on the Serial Monitor, so I know the Arduino is pulling its weight, but the TouchShield is displaying a ‘-1′ which I assume means that it’s not seeing the serial. Something is not lining up.
