I can't put a condition to activate the scanning mode(like pressing a button or something...)
I can't get any info on the sample code to let it do that.
please if anyone know how to do that please reply. I'll appreciate that
2021-02-25 09:45:58 You can execute routine 4 after detecting the key press, and you only need a simple if statement to complete the judgment. But if you don't press the buttons on the fingerprint module, how do you collect fingerprints? If you want to compare two fingerprint samples in the sample library, this function is not open. userHeadPic 347945801
2021-02-24 22:11:31 I know that but I just don't want to enter fingerprint comparison mode by pressing the sensor, instead I want to enter comparison mode by pressing a specific button that is connected on my arduino but I just can't make it happen with normal arduino code. userHeadPic jay20030327
2021-02-07 11:39:09 I think you want to collect the fingerprint image and compare it with the fingerprints in the fingerprint library.Routine 4 should meet your needs .If it is sample 6, when finger press down, the blue LED blinks quickly 3 times, which means it enters fingerprint comparison mode userHeadPic 347945801
2021-02-06 08:16:56 I would like to let the sensor go into fingerprint comparison mode to do the fingerprint matching by pressing a button userHeadPic jay20030327
