i want a fingerprint based User Verification Program with It's header file inclusion in Embedded C. help !
thanks!
<code is that but where is. h file program not working without. h file >
If you understand that code you would not need any header file.
If you see a need for a header file, you would then face much greater issues.
What magic hardware do you think is connected to the serial port for reading finger prints and reporting back which print it matched? As long as you don't know that part, the header file is totally irrelevant.
but programing contian errors without header file
in th project error is there is no. h file
#include<reg52.h> #include<lcd.h> #include<serial.h> #include<string.h> sbit SW = P3^7; sbit motor1 = P2^0; unsigned char D[20]; unsigned char i,value; bit flag; void Disp_Hex(unsigned char); void FINGER_FUN_IDT(); // finger identification void serial(void ) interrupt 4 { if (RI) { D[i] = SBUF; if (i>15){flag=1;} else i++; } } void main() { bit scan_flag; SConfig(); scan_flag=0;motor1= 0; LCD_Init(); LCD_Cmd(0x80); Disp_Str(" WELCOME "); Delay(50);clear(); LCD_Cmd(0x80); Disp_Str(" finger print "); LCD_Cmd(0xC0); Disp_Str(" BASED PROJECT "); Delay(100); LCD_Cmd(0x80); Disp_Str(" PRESS SWITCH "); while(1) // infinite loop { LCD_Cmd(0x80);Disp_Str(" PRESS SWITCH "); if (SW==0) //scanning switch { FINGER_FUN_IDT(); //command identify function EA=1;ES=1; Delay(300); } if (flag==1) { flag=0; if (D[12] == 0x00 && D[13] == 0x00 && D[14] == 0x00) { scan_flag=1; LCD_Cmd(0x80); Disp_Str(" VALID "); LCD_Cmd(0xC0); Disp_Str(" PERSON1 "); } else if (D[12] == 0x00 && D[13] == 0x00 && D[14] == 0x01) { scan_flag=1; LCD_Cmd(0x80); Disp_Str(" VALID "); LCD_Cmd(0xC0); Disp_Str(" PERSON2 "); } else if (D[12] == 0x00 && D[13] == 0x00 && D[14] == 0x02) { scan_flag=1; LCD_Cmd(0x80); Disp_Str(" VALID "); LCD_Cmd(0xC0); Disp_Str(" PERSON3 "); } else if (D[12] == 0x02) { LCD_Cmd(0xC0); Disp_Str("NO F.P ON SENSOR"); } else if (D[12] == 0x09) { LCD_Cmd(0xC0); Disp_Str("NO F.Pwere FOUND"); } EA=ES=0; } if (scan_flag==1) { Delay(100); LCD_Cmd(0x80); Disp_Str(" DOOOR OPEN "); motor1=0; Delay(600); LCD_Cmd(0x80); Disp_Str(" DOOR CLOSED "); motor1=1; Delay(600); motor1=0; } } //infinite loop end } // main loop end void FINGER_FUN_IDT() { Send_Char(0xEF);Send_Char(0x01); Send_Char(0xFF);Send_Char (0xFF);Send_Char(0xFF);Send_Char (0xFF); Send_Char(0x01); Send_Char(0x00);Send_Char(0x03); Send_Char(0x01); Send_Char(0x00);Send_Char(0x05); }
The program given upside is used as .h file in inclusion for Embed C. Actually that program is not working so proper with those values, the digital data of the fingerprint ridge&valley pattern which is saved in form of an array. So that, just help for such minor problems occuring their (Or by other program). Thank!
I aslo want the full program above program is contain error
Okay Guys..here I have the header files used in that program ,take a look !
[1] LCD.h File
#include<reg52.h>
/*LCD CONNECTION*/ #define lcd P2
sbit rs=P0^1; sbit rw=P0^2; sbit en=P0^3;
/*LCD FUNCTIONS DECLARATION*/ void lcd_init(void); void cmd(unsigned char); void disp(unsigned char); void str(unsigned char *); void delay(unsigned int);
/*LCD INITIALIZATION FUNCTION*/ void lcd_init(void) { cmd(0x38); //INITIALIZE LCD AS 2 LINE & 5X7 MATRIX (8-BIT MODE) cmd(0x0e); //DISPLAY 'ON' CURSOR BLINKING cmd(0x01); //CLEAR DISPLAY SCREEN cmd(0x06); //SHIFT CURSOR TO RIGHT cmd(0x08); //DISPLAY 'OFF' CURSOR 'OFF' } void cmd(unsigned char c) { lcd=c; rs=0; rw=0; en=1; delay(2); en=0; }
void disp(unsigned char ch) { lcd=ch; rs=1; rw=0; en=1; delay(2); en=0; }
void str(unsigned char *s) { while(*s) disp(*s++); }
void delay(unsigned int k) { unsigned int i,j; for(i=0;i<k;i++) for(j=0;j<1275;j++); }
[2] SERIAL.h Files
(Ok, here are 2 file of that, u can use any of them i' selected 2nd one.)
......./I/.......
/* FUNCTION & BIT INTIALIZATION */ void uart_init(void) { SCON=0x50; TMOD=0X20; TH1=TL1=-3; TR1=1; }
/* FOR WRITING DATA TO LCD DISPLAY */ void tx(unsigned char ch) { SBUF=ch; while(TI==0) TI=0; }
/* FOR RECEIVING ANY DATA*/ unsigned char rx(void) { while(RI==0) RI=0; return SBUF; }
main() { unsigned char c; uart_init(); while(1) { c=rx; tx(c); } } "OR"
......./II/.......
/* Transmit only */ #include<reg52.h>
/**VARIABLES DECLARATION**/ bit flag; bit r_flag = 0; int i=0; char idata buff[20],ch;
/**INTERRUPT SERVICE ROUTINE**/ void serial_intr(void) interrupt 4 { if(TI == 1) { TI = 0; flag = 1; } else if(RI==1) { ch=SBUF; if((ch!='\r') && (ch!='\n')) buff[i++]=ch; else buff[i++]='\0'; if(ch=='\n') { r_flag=1; i=0; } RI=0;
}
/**TRANSMISSION FUNCTION**/ void print(char *str) { while(*str) { flag = 0; SBUF = *str++; while(flag == 0); }
the blind is leading the deaf.
there is an abundance of requests for code by someone that does not even have an inkling of the issues.
AGAIN: if you can not code it yourself 'reference code' is worthless</>

Hiii.. my project is biometric system for ATM using fingerprint sensor.. i have to use R305 fingerprint sensor using 8051 microcontroller.. please give me coding of connectivity of both in c language.. thanks..
Hiii.....
Iam doing the same project right now. Can you please provide the entire code of this project. I badly need it at present.
