Minized tutorial PDM microphone reference design

100fotis over 6 years ago

Hi everyone

I am trying to run the simulink model for this turorial but i get this error

Invalid setting in 'microphone_PDM/PDM_audio/From Workspace' for parameter 'VariableName'.

Caused by:

Error evaluating parameter 'VariableName' in 'microphone_PDM/PDM_audio/From Workspace'

Undefined function or variable 'ila_data_struct'.

Does anyone have an idea why that happens? thanks in advance

Also, i am new to matlab & simulink, and i have the 2017.1 vivado and matlab 2016.b, the versions mentioned in the official site.

Could you point me to the "PDM microphone reference design" that you mentioned? I don't recall publishing a tutorial or Simulink model that uses the mic.

Thanks,
/Matt

Please see http://zynqgeek.zedboard.org/content/minized-pdm-reference-design. The reference design was published for a specific tools version and that was of course quite a while ago. In November 2018 it was OK to override the tools version with version_override=yes, but of course we cannot guarantee that this will always be OK.
