1284p and touchshield slide

Other Hardware 3rd Party Boards
1

Hello,

I'm trying to setup a 2-way serial communication between 2 devices:
TouchShield Slide (from Liquidware) from/to atmel 1284p using
SoftwareSerial library.

I've setup a test example to see how it works ( arduino UNO and
TouchShield Slide) and it'is work fine but when I try with 1284p don't

work :frowning:

I upload the sketch to 1284p with a avr programmer ( without a
bootloader) and I use mighty-1284p core with this pin mapping

Sketch for 1284p

#include <SoftwareSerial.h>

// RX1/INT0 (D 10) PD2 16
// TX1/INT1 (D 11)

#define RX_PIN 10
#define TX_PIN 11

SoftwareSerial touchSerial = SoftwareSerial(RX_PIN, TX_PIN);

// Globals

long randNumber;

void setup() {
touchSerial.begin(9600);
}

void loop() {
randNumber = random(300);

if(touchSerial.available())
{
char c = (char)touchSerial.read();
if (c == 'A')
{
touchSerial.print(randNumber);
delay(100);
}
}
}

sketch for TouchShield

// Globals
unsigned int Xstore;
unsigned int Ystore;

// Prepare Screen and Serial
void setup()
{
background(0,0,0);
stroke(255,255,255);
fill(0,0,0);
Serial.begin(9600);
delay(100);
}

void loop()
{
// Monitor TouchShield Slide for touches
gettouch();

// Check if there are new touches
// If yes, send serial command to Arduino
if ( mouseX != Xstore || mouseY != Ystore )
{
Serial.print("A");
delay(50);
}

Xstore = mouseX;
Ystore = mouseY;

// Monitor Serial Buffer of TouchShield Slide
char charIn = 0;
byte i = 0;
char stringIn[32] = "";

while(Serial.available()) {
charIn = Serial.read();
stringIn = charIn;

  • i += 1;*
    }
    // Clear screen and display the serial buffer as text
    if (stringIn[0])
    {
  • background(0,0,0);*
  • text(stringIn, mouseX+75, mouseY+75, 30, 30);*
    }
    }
    what is wrong? How i can debug it?
    thanks
