Hi Thanks for response ,

I confuse between SDIN & LRCK pins configuration. 

In datasheet both are used  to select channel (left or right).

could you please explain me.

Could you please share sample code of TAS5720 with any generic controller.

1. What is use of I2C signals if we have I2S signals?

2. LRCK pin needs to configure as clock or gpio ( toggle high / low) just to select channel?

3. How to configure SDIN pin in generic controller if I2S peripheral not available.

4. what should be he configuration of SDIN pin & how to load data in SDIN pin?

Hi , i am communicating with TAS5720A- Q1EVM board. MCLK, SCLK, LRCK, SDIN pin functionality not implemented.

i just want to communicate with TAS5720 EVM board using I2C pins of my controller.

TAS5720 address is 0x6C. i am sending command to write volume but getting NACK from EVM (my first command in software).

Please check below snap.

my I2S clock  is 100kHz.

is there any configuration need to do to use EVM as software control?

If you do a second I2C command after the first NACK do you see the same behavior

best regards,
Luis

Yes , Observed same behavior after second command. NACK.

Please check below code snap 

Note : i just connected SDA, SCL & 3.3v & GND of TAS5720 to My controller. 

Hello Rahul,

If you configure the I2C address to 0x6D do you see the same issue.

best regards,

Luis

yes, same issue. i tired slave address 0x6D (pull high ADR) and ADR pulled low for slave address 0x6C.

What should be the state of SPK_SD pin while sending command (HIGH / LOW)? 

Hi , Luis mu I2C communication issue is resolved. Now i received ACK from TAS5720A- Q1EVM board. issue was in i2c pull circuit.

Now I am working on I2S communication. MCLK is not available in my microcontroller I2S peripherals so i generated MCLK using timer with 50% duty.

Could you please help me to config MCLK & SLCK frequency.

what should be the value (Standard / Default configuration) of MCLK & SCLk  in Khz ?
