Erich,

The FDK does not store an image of the fingerprint if that is what you are thinking about. This would take too much memory. The FDK analyzes the scanned fingerprint and extracts features and stores information about the features in a database.

Hello Erich,

You can show the intermediate images of the FDK image processing flow by...

Connecting to the FDK with emulator,
Opening the FDK_Demo project in CCS4 (located on the FDK CD-ROM at <DIR>\C5515 Fingerprint Development Kit\Software\C5515_code_development\FDK_Demo),
Setting breakpoints in the TA_GetFeature function (located at the very bottom of TA_demo_algo.c),
Opening the CCS4 Image Analyzer (Tools --> Image Analyzer) and entering the configuration shown in the below screen shot.

If you want to display the fingerprints during run-time, you would have to modify the source code accordingly and burn it into the SPI Flash.

Hope this helps,
Mark

Thanks Mark,

That is what I want to ask the question. Can you send me the source code for "Setting breakpoints in the TA_GetFeature function (located at the very bottom of TA_demo_algo.c)", and "modify the source code accordingly and burn it into the SPI Flash." (My Email: dhdanh92@student.ctu.edu.vn). If you do not mind please detailed instructions (Image Instructions) because I do not have specialized.

Once more question, My FDK board don't work accuracy after I had used RS232 cable to connect on the PC. Now my FDK board don't show any sound signal when I press any button.

I need emulator to show the fingerprint image on PC. But my FDK board don't have any Emulator when I receive FDK board from TI Corp. Can I buy Emulator and JTAG?

Thanks for your answer

Hello Mark,

I tried to display the fingerprint during debug as you wrote.

But I can't change "Page type" field. I choose DATA from list, press Enter and field become clear. All other fields changes successfully.

And I see bad fingerprint image.

What am I doing wrong?

Hi Alex,

I met with the same problem, then I output the data to a file and use Matlab to display it.

P.S. I have just created a google group to discuss questions about this FDK, please join us. Mark is in this group too.

Thanks!

I dont think it complies with the standard ISO 19794-2. it is Tooan proprietary format.

Somebody please correct me.

It will be good to have the format open so. Can somebody help?

Best Regards

Hey Alex Kuzim,

I think you should set your Page Format to DATA so that it read specifically from RAM. If it does not allow you to set the DATA field, just close the window and open a new one. Just changing the selected tab worked for me.

Hope it works for you.
