iPod Serial play/pause

Projects Programming

So, I've run out of compiling errors, but I still get no response from the iPod.

This is where the code stands:

#include <iPodSerial.h>
#include <SimpleRemote.h>

SimpleRemote simpleRemote;

// initialize
int pingPin = 7          ; // Serial for Ping)))
int podPin = 0           ; // IPod TX, board RX
int podPout = 1          ; // IPod RX, board TX
int pingBaud = 9600      ; // Ping))) Baud rate
int podBaud = 19200      ; // IPod Baud rate
int threshOn = 20;
int threshOff = 40;
 
// set up
void setup() {
  iPodSerial(); // Setup iPodSerial
}

unsigned long pp = 0;

void loop() {
  simpleRemote.sendiPodOn();
    delay(50);
    simpleRemote.sendButtonReleased();
    simpleRemote.sendPlay();
    delay(5000);
}
/*
  pp = Ping();
  while (pp > threshOn){
    delay(500);
    break;
  }
  if (pp < threshOn) {
    simpleRemote.sendiPodOn();
    delay(50);
    simpleRemote.sendButtonReleased();
    simpleRemote.sendPlay();
    while (pp < threshOff){
      pp = Ping();
      delay (500);
    }
  }
  simpleRemote.sendiPodOn();
  simpleRemote.sendButtonReleased();
  simpleRemote.sendPlay();
  simpleRemote.sendSkipBackward();
}
*/

unsigned long Ping(){
  Serial.begin(pingBaud);
  int x = 0;
  pinMode(pingPin, OUTPUT)    ;
  digitalWrite(pingPin, LOW)  ;  // init sensor to ensure clean HIGH pulse
  delayMicroseconds(2)        ;  
  digitalWrite(pingPin, HIGH) ;  // make the sensor send a pulse 
  delayMicroseconds(5)        ;  
  digitalWrite(pingPin, LOW)  ;  // Set LOW again
  pinMode(pingPin, INPUT)     ;  // Get ready to capture the duration of the resulting pulse
  // Capture how long the pin stays in HIGH state.
  unsigned long Duration = pulseIn(pingPin, HIGH) ;  
  x = Convert_Time_Space(Duration) ;
  delay(500);
  return x;
}
 
unsigned long Convert_Time_Space(const unsigned long fnDuration )
{
  // I used 29 microseconds per cm. 
  // 40kHz supersonic burst
  // 1130 fps -> 29.0339814 microseconds per cm
  return fnDuration / 29 / 2 ;
}

and as for hardware, it's right outta this:

With the exception that my power runs straight from 5v to the iPod, since it actually charges that way. But since that has nothing to do with TX/RX, forget it.

Anyone see what I'm doing wrong here?
