SM630

Hi,,

I am new to Arduino forum,

I am interfacing SM630 fingerprint module to uC but this module not responding. When i am sending command packet according to given in manual but their no response from it.

I searched for "SM630" and found images of motorcycles. Any chance you want to take the time to post a few more details?

you search for " SM630 fingerprint module ".

you search for " SM630 fingerprint module ".

Is that what I said? Add (any) details and maybe you'll get some help.

this is hardware I am using.

while(1)
            {
            
            serial_TX_data(0x4D);
            serial_TX_data(0x58);
            serial_TX_data(0x10);
            serial_TX_data(0x03);
            serial_TX_data(0x40);
            serial_TX_data(0x00);
            serial_TX_data(0x00);
            serial_TX_data(0xF8);
            
            i0=serial_RX_data();      
                  
            i1=serial_RX_data();      

            i2=serial_RX_data();      
            
            i3=serial_RX_data();      
            
            i4=serial_RX_data();      
            
            i5=serial_RX_data();      
                        
            i6=serial_RX_data();      
                        
            i7=serial_RX_data();      
            
            }

in this code i am sending command for adding fingerprint to module and waiting for receiving response from module. but their is no response from it .

you can check data sheet for it from http://www.8051projects.info/datasheets/SM-630-fingerprint-module.pdf.

now you can get every details of it. :slight_smile:

I am interfacing SM630 fingerprint module to uC but this module not responding.

OK, the schematic is a start. The uC you talk about above, is it an Arduino board? If so it cannot be wired directly to an RS-232 interface as the voltage levels will be wrong and will damage an arduino. If being used with an arduino you first need a RS-232 to TTL serial convert cable or circuit. So before going further, are you wishing to wire this module directly to an arduino board?
