TLV320ADC3101EVM-K: PPS flow issue

wxyxiangyang

Dear Expert

I build a processing flow in the PPS , and download to the EVM successfully, but the final result displayed using the Audacity software shows no changing of the timewave, e.g, I apply the Absolute algorithm in the DSP. then in theory, every point should turn positive. but the result is not like that, could you tell what is the issue?

wxyxiangyang,

I would need to see your process flow. can you share it?

best regards,

Dear Wilson,

the attached is the process flow, I tried many times but failed. the process flow can "download and run" successfully into the EVM. but the result timewave form from the Audacity do not have any response related with the process flow; I do not know what is the issue.

only the CCS software can successfully control the EVM. but as you know, CCS can not generate the process flow.

I want to verify the algorithm based on the process flow and then transfer to my own device

Hi wxyxiangyang,

Steve is out of the office, can you tell us if you've resolved the issue? If not, can you try submitting your process flow again?
