AFE4300 Atmel

malik adeel

Hi,

I managed to successfully interfaced, AFE4300 EVM to arduino by removing the Mbb3 board, and my code worked fine. Then i translated all that to a pcb, with Atmel chip and AFE4300, but for some reason i cannot communicate with AFE4300 chip..

for reference i am attaching my schematic with this email.

Malik,

Have you tried looking at the SPI lines on the working board and compare that to the board you having the communication problem on?

yes,

I have and am getting almost similar signal waveforms on scope... except miso pin.. it constantly seems to be moving up and down. like its floating.

any reasons for that ?

There could be many reasons, but nothing to do with the AFE. Have you verified connectivity on the layout? Sanity check all of your connections.
