Part Number: TAS2770EVM
Other Parts Discussed in Thread: TAS2770,

Hi there,

I am new on Tas2770 EVM. I am looking for the instructions to wire the Tas2770EVM with STM32H757i-EVAL on I2C and I2S (SAI) for audio development.

Can someone kindly advise if reference doc and source code is available?

Thanks,

Andy

Andy,

For the stereo TAS2770 EVM, you can wire in external I2S from your STM board on the INPUT headers then set the J2 jumper to select the external source.

See the EVM user guide for more detail: www.ti.com/.../slou497.pdf

TI does not provide any reference code for STM32 in this case.

Hi Brian,

Thanks for the information.

If I want to have my audio data from the INPUT wire instead of USB HOST source, do I have to setup jumper or registers?

BRs,

Andy

Hi Andy,

You will have to connect jumpers J2 and J6 while you input I2C/TDM data from wire. EVM User's guide section 7.1.2 has more details on this connection.
