Hi,
In one of my project I am interfacing my TLC320AIC3101 with Atmel SAM3x for recording the voice received from mic. I have interfaced the BCLK,WCLK,DOUT and DIN to the i2s lines of SAM3x controller at TK,TF,RD and TD respectively. There is no MCLK as I want to use BCLK as MCLK as mentioned in TLV320AIC3101 datasheet as "CLKDIV_IN can be MCLK or BCLK, selected by register 102, bits D7–D6." or "PLLCLK_IN can be MCLK or BCLK, selected by Page 0, register 102, bits D5–D4". I have connected the i2c lines of TLV320AIC3101 to my SAM3x i2c where SAM3x i2c is acting as i2c Master.
I am successfully able to read and write the registers of TLV320AIC3101 using my SAM3x i2c Master driver. Now I want to know which registers I can set so that when I speak through the mic and I get the voice in i2s or loopback to headphone and also how do I test the headphone by playing a sinewave on i2s?
Which mode should I use CLKDIV_IN mode or PLL mode?
Here is the code I am trying but don't know why it is not working
/* Configure AIC3101 */
i2c_write( 0, 0 ); // Page select register -> Page 0
i2c_write( 1, 0x80 ); // Reset AIC3101
/* Configure AIC3101 registers */
data = i2c_read(3); // just to see if i2c is working
i2c_write( 7, 0x0A ); // 7 Codec Datapath Setup <- [FS=48 kHz][LeftDAC=LEFT][RightDAC=RIGHT]
i2c_write( 9, 0x00 ); // 9 Audio Interface Control B <- [I2S mode][16 bit]
i2c_write( 15, 0 ); // 15 Left ADC PGA Gain <- [Mute=OFF]
i2c_write( 16, 0 ); // 16 Right ADC PGA Gain <- [Mute=OFF]
i2c_write( 19, 0x04 ); // 19 LINE1L to Left ADC <- [SingleEnd][Gain=0dB][Power=ON][SoftStep=OncePerFS]
i2c_write( 22, 0x04 ); // 22 LINE1R to Right ADC <- [SingleEnd][Gain=0dB][Power=ON][SoftStep=OncePerFS]
i2c_write( 27, 0 ); // 27 Left AGC B <- [OFF]
i2c_write( 30, 0 ); // 30 Right AGC B <- [OFF]
i2c_write( 37, 0xE0 ); // 37 DAC Power & Output Dvr <- [LeftDAC=ON][RightDAC=ON][HPLCOM=SingleEnd]
i2c_write( 38, 0x10 ); // 38 High Power Output Dvr <- [HPRCOM=SingleEnd][ShortCircuit=OFF]
i2c_write( 43, 0 ); // 43 Left DAC Digital Volume <- [Mute=OFF][Gain=0dB]
i2c_write( 44, 0 ); // 44 Right DAC Digital Volume <- [Mute=OFF][Gain=0dB]
i2c_write( 47, 0x80 ); // 47 DAC_L1 to HPLOUT Volume <- [Routed]
i2c_write( 51, 0x09 ); // 51 HPLOUT Output <- [Mute=OFF][Power=ON]
i2c_write( 58, 0 ); // 58 HPLCOM Output <- []
i2c_write( 64, 0x80 ); // 64 DAC_R1 to HPROUT Volume <- [Routed]
i2c_write( 65, 0x09 ); // 65 HPROUT Output <- [Mute=OFF][Power=ON]
i2c_write( 72, 0 ); // 72 HPRCOM Output <- []
i2c_write( 82, 0 ); // 82 DAC_L1 to LEFT_LOP/M Volume <- []
i2c_write( 86, 0 ); // 86 LEFT_LOP/M Output <- []
i2c_write( 92, 0 ); // 92 DAC_R1 to RIGHT_LOP/M Volume <- []
i2c_write( 93, 0 ); // 93 RIGHT_LOP/M Output <- []
i2c_write( 101, 0x00 ); // 101 GPIO Control Register B <- [CODEC_CLKIN = PLLDIV_OUT]
i2c_write( 102, 0xA2 ); // 102 Clock Generation Control <- [PLLCLK_IN and CLKDIV_IN use BCLK]
data =0x00;
data = i2c_read(14);
if(data&0x10)
{
printf("\nHeadset Detected");
}
/* Play Tone */
for ( sec = 0 ; sec < 10 ; sec++ )
{
for ( msec = 0 ; msec < 1000 ; msec++ )
{
for ( sample = 0 ; sample < 48 ; sample++ )
{
i2s_write(sinetable[sample]);
}
}
}
/* Close Codec */
i2c_write( 0, 0 ); // Page select register -> Page 0
i2c_write( 1, 0x80 ); // Reset the AIC3101
Can someone please help me in making it work? I have the EVM development kit and arduino due board.I am using Atmel Studio with ASF for my development. The EVM software does not work on my windows 8 machine. So can experiment on that.
