I am working off the TIA example project and I am measuring a photodiode.  Its working great and the output voltage on the TIA component changes with light intensity.  When I add the comparator component isolated by it self unhooked to anything the TIA component output stays constant.  I have it disabled for now but I am unsure whats causing this.  I had intended on taking the output of the TIA and using it as an input to the comparator.

Hi,

I tested by placing an IDAC component in the design and incrementing the IDAC code in the main loop. I could see the TIA output changing. Please find the project attached.

Best Regards,

alexander.roscoe,

What are the warning / error messages reported? Normally, the project won't compile if Comparator's terminals are not connected.
