Dear all, here i m using R305

[Disha raka]

Dear all,

 

here i m using R305 Finger print module with P89V51RD2

but my program is not working please see my program n say me corrections,

or give me your code please…

its urgent friends…

 

 

program:

 

 

#include<reg51.h>

#include<string.h>

 

sfr ldata=0x90;

sbit rs=P2^3;

sbit rw=P2^4;

sbit en=P2^5;

sbit busy=P1^7;

sbit S1=P3^2;

sbit S2=P3^3;

sbit S3=P3^4;
