Original question:

TAS2781EVM: Taking measurements of TAS2781EVM with an AP525

TAS2781EVM: Setting up TAS2781EVM And PPC3 for I2S input

Paul Edwards80
Prodigy 90 points

Part Number: TAS2781EVM

I have :
1) Removed the shunt a J24
2) Set the TDM parameters in PPC3 to match the I2S setting from the AP525
3) Put an I2S signal from an AP525 DSIO module on SBCLK, FSYNC and SDIN with the same voltage as the EVM IOVDD as measured at J17

I don't get an output from the EVM...

What am I missing?
