PGA300EVM-034: Error on Guided Calibration

Walter Topp

Part Number: PGA300EVM-034

Hello,

when I select a Calibration file, I get an Error message: "The selected calibration file doesn't match with the GUI version..."

Pressing OK to continue the calibration, it seems to work: "OWI Configuration": no error - "OWI Actiovation": nothing to do because OWI is active (pressing next), reading of registers starts, but than the monitor is clear and the following error appears:

Unexpected Error occured during calibration

Error -20145 occurred at Error occured during interpolating values

Possible reason(s):

Analysis: Each independent variable must contain the same number of values as the dependent variable.

Try calibrating again

What can I do? I installed the latest version (3.5.1.0) from the GUI and I use the original ini-files...

Thanks for any help

Walter

    Hi Walter,

    Can you go through the settings on the "Calibration Settings File" page after selecting a .ini file and double check that there are the correct number of temperature points, pressure points, and DAC data sets? For example:

    In this case there is 1 temperature point, 3 pressure points, and 3 sets of DAC codes with a corresponding desired output voltage. It's strange that the default .ini files might have an error here, but it seems like one of these fields is incorrect on your setup.

    Regards,

    Hi Scott,

    Thanks for your hints, but I can't see a mistake in my ini Files - I used the original TI files...

    I'm using a PC with WIN10, but I will try an other PC with a clean installation. My be, there is a mistake.
