Hello. Greetings to all. I am new to the arduino. Want to know how to change the password of fingerprinter ZFM-20. The technical specifications I saw that the instruction code is 12 h but not how to set it in arduino language. Thanks for your time
SOLVED. The password change is not implemented in the sample routines. You need to create the class in the file. H and routine. CPP code instruction is 12H. regards
