ulta slim 4750 finger printer reader and CPE error

by taymota on Sun Jun 06, 2021 1:18 pm

I keep coming across and issue using the adafruit_fingerprint circuit python lib on both the itsy and circuit playground. I have lib loaded and have been able to get the ready to the point of being able to read by removing some code from the "fingerprint_template_file_compare" anytime i try to go through the enroll_save_to_file call i get errors in get_gpdata .
I have not seen allot on the pid#4750 so is there something different i need to do for this sensor over the others on the site ?
I have opened up the adafruit_fingerprint.py but not sure where to look next .

Looks like you may be running into a memory issue. Does the simpletest example run OK?
