hi guys iam making a biometric fingerprint based voting machine, and iam facing problem in interfacing SM630 with µc(At89s52). Please help in codes for interfacing sm630 with µc.
The problem is, there is no response from module when any command is send from µc. i dont know my codes are right or not, but tell me the algorithm how to interface. I just ‘ve 6 days, i ‘ve to complete the coding part and make PCB.
