hey guys,
Can you guys take a look at the sketch I wrote for the arduino + sparkfun's audio sound module(http://www.sparkfun.com/products/9534
)? Basically since the module plays files named 0x0001 to 0x0500, I am making a sketch that takes 3 numbers that tell the module which file to play. First I concatenate those 3 numbers as decimals since 0's on the left can be ignored once I convert to hex. Then I sprintf it hex. I'm not quite sure if my syntax is right or if this is the right approach. I based my code largely off
http://yapan.googlecode.com/svn/trunk/arduino/examples/SOMO_14D_Test/SOMO_14D_Test.pde
int total=0;
char buf[8]={0};
const int clockPin = 2; // the pin number of the clock pin
const int dataPin = 3; // the pin number of the data pin
const int busyPin = 4; // the pin number of the busy pin
const int resetPin = 5; // the pin number of the reset pin
const unsigned int VOLUME_7 = 0xFFF7;
const unsigned int STOP = 0xFFFF;
void setup(){
Serial.begin(9600);
pinMode(clockPin, OUTPUT);
pinMode(dataPin, OUTPUT);
pinMode(busyPin, INPUT);
pinMode(resetPin, OUTPUT);
digitalWrite(clockPin, HIGH);
digitalWrite(dataPin, LOW);
// reset the module
digitalWrite(resetPin, HIGH);
delay(100);
digitalWrite(resetPin, LOW);
delay(10);
digitalWrite(resetPin, HIGH);
delay(100);
sendCommand(VOLUME_7);
}
void loop(){
if (Serial.available() > 0) {
int moveServo = Serial.read();
Serial.flush();
if (moveServo =='a'){
//audio begins, stop haros movement and start looping
myservo.write(94);
//get first 3 bit of incoming data 001-500 for file name
while(Serial.available()<3){
}
for(int i=0;i<3;i++){
//gets decimal concat, ignores 0’s on left
total=total*10+Serial.read();
}
sprintf(buf,%X",total)
sendCommand(buf);
delay(1000);
}
}
void sendCommand(unsigned int command) {
// start bit
digitalWrite(clockPin, LOW);
delay(2);
// bit15, bit14, ... bit0
for (unsigned int mask = 0x8000; mask > 0; mask >>= 1) {
if (command & mask) {
digitalWrite(dataPin, HIGH);
}
else {
digitalWrite(dataPin, LOW);
}
// clock low
digitalWrite(clockPin, LOW);
delayMicroseconds(200);
// clock high
digitalWrite(clockPin, HIGH);
delayMicroseconds(200);
}
// stop bit
delay(2);
}
thanks for the help
