that didnt work either  

here is the example code stripped Ill re add my code wen this works!

Code:

/*  PS2Keyboard library example
  
  PS2Keyboard now requries both pins specified for begin()

  keyboard.begin(data_pin, irq_pin);
  
  Valid irq pins:
     Arduino:      2, 3
     Arduino Mega: 2, 3, 18, 19, 20, 21
     Teensy 1.0:   0, 1, 2, 3, 4, 6, 7, 16
     Teensy 2.0:   5, 6, 7, 8
     Teensy++ 1.0: 0, 1, 2, 3, 18, 19, 36, 37
     Teensy++ 2.0: 0, 1, 2, 3, 18, 19, 36, 37
     Sanguino:     2, 10, 11
  
  for more information you can read the original wiki in arduino.cc
  at http://www.arduino.cc/playground/Main/PS2Keyboard
  or http://www.pjrc.com/teensy/td_libs_PS2Keyboard.html

It did so. It just didn't do what you wanted.

So, what did you want it to do, and what did it do?

[Reply #17 on:]

What library are you using from here? http://playground.arduino.cc//Main/PS2Keyboard

[Reply #18 on:]

it Works I had to change some stuff but it works You guys rock thanks!

[Reply #19 on:]

Great! What did you change? Could you post your working code, with comments so others can see too?

[Reply #20 on:]

here is the working code. Only thing I'd like to be able to also read  PS2_DELETE
but I couldn't get that working but this works for now.

Code:

// arduino serial terminal  

#include <PS2Keyboard.h>
#include "Wire.h"
#include "LiquidCrystal.h"

LiquidCrystal lcd(0); // set lcd i2c adress
int reset_pin = 13;  // reset pin on the arduino mega
const int DataPin = 3; // data pin for ps/2
const int IRQpin =  2; // clock pn for ps/2
char line[16]; // store char array
int count = 0; // counter
unsigned long time = 60000; // 1 minuite delay

PS2Keyboard keyboard;

void setup() {

  pinMode(reset_pin, OUTPUT); // set pin 13 to output
  digitalWrite(reset_pin, HIGH);  // set pin High
  delay(1000); // delay 1 second
  keyboard.begin(DataPin, IRQpin); // start keyboard
  Serial.begin(9600); // start serial
  delay(1000);  // delay 1 second
  lcd.begin(16, 2);  // begin lcd
  lcd.setBacklight(HIGH); // turn backlight on
  lcd.setCursor(0, 0); // set cursor
  lcd.print(":"); // print a prompt
}

void loop() {

  if (keyboard.available() ){
    char kb = keyboard.read();  // read the ps2 keyboard input


    if(kb != PS2_ENTER){ // if input does not equal enter
      lcd.print(kb); // print char to lcd
      delay(20); // delay 20 ms
      line[count++] = kb; // add chars
      delay(50);  // delay 50 ms


    }
    else{
      line[count++] ='\0';  // line = line + count = terminate
      Serial.print(line);  // print the added chars
      delay(1000);  // dealy 1 second
      count = 0;  // reset count
      lcd.clear();  // clear lcd
      delay(50);  // delay 50ms
      lcd.print ("sending"); // print sending to lcd
      delay(5000); // delay 5 seconds
      lcd.clear();  // clear lcd
      delay(50); // delay 50ms
      lcd.print(":"); // print prompt  
      delay(time); // delay 1 minuite
      lcd.print("reset");  // print reset to lcd
      delay(1000); // delay 1 second
      digitalWrite(reset_pin , LOW); // send a reset to the arduino mega
      delay(2000); // delay 2 seconds
      digitalWrite(reset_pin , HIGH);  // finish reset  
      lcd.clear();     // clear lcd
  
    }
  }
}

And here is the code to go with it  

Code:

/* max 24 relay controller and pump pulser simulator  
 
 this program takes a serial string like this "12.900.14.14"  and parses it up into variables
 for relay count 1-12, number of pulses, pulse width, and delay beween pulses.
 Then it prints that to the serial port like this "Relays 12 Pulses 900 Length 14ms Delay 14ms"
