Finger Print Sensor, which we used to see in Sci-Fi movies a few years back, is now become very common to verify the identity of a person for various purposes. In present time we can see fingerprint-based systems everywhere in our daily life like for attendance in offices, employee verification in banks, for cash withdrawal or deposits in ATMs, for identity verification in government offices etc. We have already interfaced it with Arduino and with Raspberry Pi, today we are going to interface Finger Print Sensor with PIC microcontroller. Using this PIC microcontroller PIC16f877A Finger Print System, we can enroll new fingerprints in the system and can delete the already fed fingerprints. Complete working of the system has been shown in the Video given at the end of article.
Required Components
- PIC16f877A Microcontroller
- Fingerprint Module
- Push buttons or keypad
- 16x2 LCD
- 10k pot
- 18.432000 MHz Crystal Oscillator
- Bread Board or PCB (ordered from JLCPCB)
- Jumper wires
- LED (optional)
- Resistor 150 ohm -1 k ohm (optional)
- 5v Power supply
Circuit Diagram and Explanation
In this PIC Microcontroller Finger Print sensor interfacing project, we have used 4 push buttons: these buttons are used for multifunctioning. Key 1 is used for matching the finger print and increment fingerprint ID while storing or deleting the fingerprint in the system. Key 2 is used for enrolling the new fingerprint and for decrement fingerprint ID while storing or deleting fingerprint in the system. Key 3 is used for delete stored finger from the system and key 4 is used for OK. A LED is used for an indication that fingerprint is detected or matched. Here we have used a fingerprint module which works on UART. So here we have interfaced this fingerprint module with PIC microcontroller at its default baud rate which is 57600.
So, first of all, we need to make the all the required connection as shown in Circuit Diagram below. Connections are simple, we have just connected fingerprint module to PIC microcontroller’s UART. A 16x2 LCD is used for displaying all messages. A 10k pot is also used with LCD for controlling the contrast of the same. 16x2 LCD data pins are connected PORTA pins. LCD’s d4, d5, d6, and d7 pins are connected with Pin RA0, RA1, RA2, and RA3 of PIC microcontroller respectively. Four push buttons (or keypad) is connected to PORTD’s Pin RD0, RD1, RD2, and RD. LED is also connected at port PORTC’s pin RC3. Here we have used an 18.432000 MHz external crystal oscillator to clock the microcontroller.
Operation of Fingerprint Sensor with PIC Microcontroller
Operation of this project is simple, just upload hex file, generated from source code, into the PIC microcontroller with the help of PIC programmer or burner (PIckit2 or Pickit3 or others)and then you will see some intro messages over LCD and then the user will be asked to enter a choice for operations. To match fingerprint user need to press key 1 then LCD will ask for Place Finger on Finger Print Sensor. Now by putting a finger over fingerprint module, we can check whether our fingerprints are already stored or not. If your fingerprint is stored then LCD will show the message with the storing ID of fingerprint-like ‘ID:2’ otherwise it will show ‘Not Found’.
Now to enroll a finger Print, the user needs to press enroll button or key 2 and follow the instructions messages on the LCD screen.
If the user wants to delete any of fingerprints then the user needs to press the delete button or key 3. After which, LCD will ask for the ID of the fingerprint which is to be deleted. Now by using increment push button or key 1(match push button or key 1) and decrement push button or key 2 (enroll push button or key 2) for increment and decrement, the user can select the ID of saved Finger Print and press OK button to delete that fingerprint. For more understanding have a look at the video given at the end of the project.
FingerPrint interfacing Note: Program of this project is a little bit complex for a beginner. But its simple interfacing code made by using reading r305 fingerprint module datasheet. All the instruction of functioning of this fingerprint module is given in the datasheet.
Here we have used a frame format to talk with fingerprint module. Whenever we send a command or data request frame to fingerprint module it responds us with the same frame format containing data or information related to applied command. All of the data and command frame format has been given in the user manual or in the datasheet of R305 fingerprint module.
Programming Explanation
In programming, we have used the below frame format.
We begin the program by setting the configuration bits and defining macros and pins for LCD, Buttons and LED, which you can check in the complete code given at the end of this project. If you are new to PIC Microcontroller then start with Getting started with PIC Microcontroller Project.
Then we declared and initialized some variable and array, and made a frame that we need to use in this project to interface fingerprint module with PIC microcontroller.
uchar buf[20];
uchar buf1[20];

const char f_detect[]={0xEF, 0x1, 0xFF, 0xFF, 0xFF, 0xFF, 0x1, 0x0, 0x3, 0x1, 0x0, 0x5};

After it, we have made LCD function to drive LCD.
void lcdwrite(uchar ch,uchar rw)
{
LCDPORT= ch>>4 & 0x0F;
RS=rw;
EN=1;
__delay_ms(5);
EN=0;
LCDPORT= ch & 0x0F;
EN=1;
__delay_ms(5);
EN=0;
}
lcdprint(char *str)
{
while(*str)
{
lcdwrite(*str++,DATA);
//__delay_ms(20);
}
}
lcdbegin()
{
uchar lcdcmd[5]={0x02,0x28,0x0E,0x06,0x01};
uint i=0;
for(i=0;i<5;i++)
lcdwrite(lcdcmd[i], CMD);
}
Given function is used for initializing UART
void serialbegin(uint baudrate)
{
SPBRG = (18432000UL/(long)(64UL*baudrate))-1; // baud rate @18.432000Mhz Clock
TXSTAbits.SYNC = 0; //Setting Asynchronous Mode, ie UART
RCSTAbits.SPEN = 1; //Enables Serial Port
TRISC7 = 1; //As Prescribed in Datasheet
TRISC6 = 0; //As Prescribed in Datasheet
RCSTAbits.CREN = 1; //Enables Continuous Reception
TXSTAbits.TXEN = 1; //Enables Transmission
GIE = 1; // ENABLE interrupts
INTCONbits.PEIE = 1; // ENable peripheral interrupts.
PIE1bits.RCIE = 1; // ENABLE USART receive interrupt
PIE1bits.TXIE = 0; // disable USART TX interrupt
PIR1bits.RCIF = 0;
}
Given functions are used for transferring commands to fingerprint Module and receiving data from fingerprint module.
void serialwrite(char ch)
{
while(TXIF==0); // Wait till the transmitter register becomes empty
TXIF=0; // Clear transmitter flag
TXREG=ch; // load the char to be transmitted into transmit reg
}
serialprint(char *str)
{
while(*str)
{
serialwrite(*str++);
}
}
void interrupt SerialRxPinInterrupt(void)
{
if((PIR1bits.RCIF == 1) && (PIE1bits.RCIE == 1))
{
uchar ch=RCREG;
buf[index++]=ch;
if(index>0)
flag=1;
RCIF = 0; // clear rx flag
}
}
void serialFlush()
{
for(int i=0;i<sizeof(buf);i++)
{
buf[i]=0;
}
}
After it we need to make a function which prepares data that is to be transmitted to fingerprint and decode the data coming from fingerprint module.
int sendcmd2fp(char *pack, int len)
{
uint res=ERROR;
serialFlush();
index=0;
__delay_ms(100);
for(int i=0;i<len;i++)
{
serialwrite(*(pack+i));
}
__delay_ms(1000);
if(flag == 1)
{
if(buf[0] == 0xEF && buf[1] == 0x01)
{
if(buf[6] == 0x07) // ack
{
if(buf[9] == 0)
{
uint data_len= buf[7];
data_len<<=8;
data_len|=buf[8];
for(int i=0;i<data_len;i++)
data[i]=0;
for(int i=0;i<data_len-2;i++)
{
data[i]=buf[10+i];
}
res=PASS;
}
else
{
res=ERROR;
}
}
}
Now, there are four function available in the code for four different task:
- Function for input the fingerprint ID – unit getId()
- Function for matching finger – void matchFinger()
- Function for enrolling new finger – void enrolFinger()
- Function for deleting a finger – void deleteFinger()
The complete code with all the four function is given at the end.
Now in the main function, we initialize GPIOs, LCD, UART and check whether the fingerprint module is connected with a microcontroller or not. Then it shows some intro messages over LCD. Finally in while loop we read all keys or push buttons to operate the project.
int main()
{

lcdinst();
while(1)
{

return 0;

Hello guys ... Please help me i am using r307 with Rpi4 with QT in C++..., i sent first passPack buffer , i received 0xFF , 0X01, 0XFF ,0XFF,0XFF,0XFF,0X07,0X00,0X03,0X00,0X00
Means its detected or not..?
And every time i send different command , i received in last 0x03,0x00,0x00
And i am not understand , why every time every command send with index 0 , why...?
Hello! What was the solution?
Hello! What was the solution? I have the same issue unfortunately... :(
What is the correct code?
And fingerprint module doesn't need a grounding?
Thanks in advance
Proteus Schematic and the code file if its possible
Thank you very much for your above answer
Please Sir if you can provide the Proteus Schematic and mplab xc8 code file , I hope you attach these files in this project, because it will be very helpfully.
model of the fingerprint sensor
what is the model of the fingerprint sensor you used?...as far i saw fingerprint sensor comes with 6 wires...but your's is 4....
and by which software i will make hax file?
microcontrollers
hello thank you very much for your projects have helped me a lot. I have a problem with the sensor, I am using the as606 but it does not recognize you, how can I solve this problem? thanks
figerprint matching
hello sir ,
i am using the stm8s207mb controller . while enrolling the finger its showing the figer stored with id number what i entered , agin i amgoing to match the figer its showing the figer detected with id 0 and score also 0, its not showing proper id what i saved. and aslo not blinkin the led in fingerprint module
Does anyone have the correct
Does anyone have the correct code for this? without the errors
Really a good job. There are
Really a good job. There are different and interesting solutions to improve my coding. I have already tried
on PIC18F4550 and PIC16F887 and works very well.
I'm just confused on the password that by default is FF,FF,FF,FF but in your code in 00,00,00,00. Why pw equal to zero works?
I wonder if this code is portable for fingerprint model R503...
Thanks for sharing your expertise in coding anyway
