Hi all,
I am trying to control MOD-MP3-XLITE with 32u4.
I have connected two boards with the UEXT cable, 5 volts to XLITE power input, TX & RX jumpers, BAT jumper.
I have one mp3 file on the SD and it works in stand alone mode.
As I understand from the example for OLIMEXINO-328 I have to serial print a command from from my controller to the XLITE board. Here is my sketch:
#define but 7
void setup(){
pinMode( but, INPUT_PULLUP );
Serial.begin(9600);
while (!Serial);
delay(1000);
}
void loop(){
static boolean key = 0;
int s = !digitalRead( but );
if( s && key == 0 )
{
Serial.print("pnum 0\r\n");
key = 1;
}
else if ( !s && key == 1 )
{
Serial.print("C\r\n");
key = 0;
}
delay(1);
}
I have also connect the 32u4 to power supply as it was written in the readme file.
What I am doing wrong?
Can anyone help me?
Thanks in advance!
