Guys,
I tried to test VS1003 with ATMEGA128 ..
I gave me "hello" on the speaker, but I can't repeat it...any ideas why ?
The code I have written :
Any clues guys ?
Thanks
I tried to test VS1003 with ATMEGA128 ..
I gave me "hello" on the speaker, but I can't repeat it...any ideas why ?
The code I have written :
Code:
void VsSineTest(){
unsigned char *p;
unsigned int i;
p = HelloMP3;
/* Reset MP3 chip */
//Mp3PutInReset(); /* Pull xRESET low -> hardware reset */
VS1003B_XRESET_L();

/* Send dummy SPI byte to initialize SPI bus of Atmel microcontroller */

//SPIPutCharWithoutWaiting(0xFF);
/* Un-reset MP3 chip */
VS1003B_XCS_H();
//Mp3DeselectControl(); /* Pull xCS high */

Any clues guys ?
Thanks
