Part Number: TAS2110EVM
Other Parts Discussed in Thread: TAS2110,

Hi TI Team,

I am using the TAS2110 EVM module with the nRF52840 chip.

I am trying to provide external i2c signals from nRF52840 chip, as per TAS21110 EVM user guide

using the default address of 0x98(8 bit addressing), which is equivalent to 0x4C(7Bit) +W/R bit.

I have provided pull-up resistor 4.7k and 3.3V i2c logic as default. when I am trying to scan the i2c address

TAS2110 EVM is not responding at all, whereas I am getting responses from other slaves.

Please help me to solve this issue, has anyone faced similar issues?

I couldn't find much support for TAS2110 EVM or any example i2c codes...

I have got ppc3 software for TAS2110 EVM, but even though I haven't got access to TAS2110 plug-in to use that.

Kindly help me make TAS2110 EVM i2c up

Best Regards

Hi, Jesse,

I would recommend to start verifying if the EVM I2C lines are working correctly. Could you provide your email address to check your access to PPC3 TAS2110 plug in? If the EVM responds correctly to the I2C communication, we can then take a look at the external I2C lines.

Hi, Jesse,

I see you have access to our TAS2110EVM plug-in. Could you take a look at the indications from Ivan about this?
