problem getting touchshield to operate arduino pin

i am gorking on a project were i am using a simple menu on a touchshield slide to operate the ports of an arduino board. so far i found an example online, but the compiler gives me the error "error compiling file" . can some one help me?

here is the code i am using for the arduino:

//Arduino Mega and Duemilanove or Diecimilia

#include <SoftwareSerial.h>
#define rxPin 3
#define txPin 2

char myByte;
int ledPin = 13;//led on pin 13
int ten = 10;//pin 10
int eleven = 11;//pin 11
int ledPinfifty = 50;//pin 50 Mega only

SoftwareSerial mySerial = SoftwareSerial(rxPin, txPin);

void setup()
{
pinMode(rxPin, INPUT);//set recieve as an input
pinMode(txPin, OUTPUT);//set transmit as an output
pinMode(ledPin, OUTPUT);//set pin 13 led driver as an output
pinMode(ledPinfifty, OUTPUT);//set pin 50 as an output
pinMode(ten, OUTPUT);//
pinMode(eleven, OUTPUT);
digitalWrite(ten, LOW);//using pin ten to act as a ground (not reccomended)
mySerial.begin(9600);
}

void loop()
{

myByte = mySerial.read();
if(myByte == 'A') //if the letter "A" comes from the touchshield
{
digitalWrite(ledPin, HIGH); //Turn on the LEDs
digitalWrite(ledPinfifty, HIGH);
digitalWrite(eleven, HIGH);
}
if(myByte == 'B') //if the letter "B" comes from the touchshield
{
digitalWrite(ledPin, LOW);//Turn off the LEDs
digitalWrite(ledPinfifty, LOW);
digitalWrite(eleven, LOW);
}

delay(5);
}

I don't see a problem. What version of the IDE are you using.

I copied it into 0018 and it compiled fine.

i am using antipasto arduino 8.13. do you have the link for arduino 0018 version? looks like that is the problem.

thank you

Here you go.

thanks

There are major differences between the Liquidware antipasto version and version 0018. Both can be made to work well. I do a most of the development work on the touchSlide drivers and I have 3 different versions of the Arduino on my machine. For the Mega/Duemilanove version 0018 will be easier for you.

I have some documentation on the slide at

http://coewww.rutgers.edu/~msproul/arduino/

In your code, you dont need to set the pin modes for rxPin and txPin, mySerial.begin will take care of that.

will i have any problem if i program the touchshield and the mega with 2 different versions??

8

i got it working. thank you.Do you have any subjection to make it more reliable? When I touch the screen, it does the function I want on the screen, but I have to repeat it few times to get the output I want on the arduino ports.

Some suggestions, yes.

Post your code. If it's a code problem, we'll see it, and tell you about it. If it's not, we'll tell you that, too. Then, you can look at hardware issues.

I have several of the TouchSLide units and have not had any problem with any of them. The only difficulty is on the Arduino that is controlling it. Most people do not use it in that fashion but write the code on the slide itself. To control it from the Duemilanove you have to use softserial which is not very reliable at high speeds

I am working on a library that will communicate via one of the megas extra serial ports and take graphic commands.

here is the code i have on the slide. i figure i have something wrong with it because i did not change anything on the arduino code and with the example it works 100% of the time while it works less that 50% of the time with my code.

can you look at it and let me know what i am doing wrong?

thanks
