reading serial numer of ibutton ds1990a??

[JOSE MANUEL]

Hello, I'm a spanish guy, and I'm going to make an access control with an ibutton.

Has somebody any example??? I have ibutton ds1990aF5, and I need to read the serial numer of this ibutton in #C in order to open the door.


Thanks���

[JOSE MANUEL]

please, I need this programm����

Jose,
You want a program that runs on a PC and is written in the C# (C-sharp)
language.

You're on the wrong forum.

This forum is about a special compiler that creates code for small
micro-controller chips. The compiler is not C#. It doesn't make
code for a PC.

NO, I want a programm for the pic 16f876a, no PC, and I need this programm in C# and after programing this pic. You understand me��

I'm seeing the example of ccs. It's here:

////////////////////////////////////////////////////////////////////////
//// EX_TOUCH.C ////
//// ////
//// This program interfaces a Dallas DS1991 touch memory device. ////
//// It will display the family code and ID of any device that ////
//// "touch"es pin B0. ////
//// ////
//// Configure the CCS prototype card as follows: ////
//// Connect pin B0 through a 4.7K resistor to +5V ////
//// Connect the touch device to GND and then "Touch" to pin B0 ////
//// ////
//// Jumpers: ////
//// PCB pin A2 to RS232 RX, pin A3 to RS232 TX ////
//// PCM,PCH pin C7 to RS232 RX, pin C6 to RS232 TX ////
//// ////
//// This example will work with the PCB, PCM and PCH compilers. ////
//// The following conditional compilation lines are used to ////
//// include a valid device for each compiler. Change the device, ////
//// clock and RS232 pins for your hardware if needed. ////

void main() {
BYTE buffer[8];
BYTE i;

printf("\r\nWaiting for a touch device...\r\n");
while (TRUE) {
while(!touch_present()) ;
delay_ms(200);
if(touch_present()) {
touch_write_byte(0x33);
for(i=0;i<8;++i)
buffer=touch_read_byte();
printf("Family: %2X ID: ",buffer[0]);
for(i=6;i!=0;--i)
printf("%2X",buffer);
printf("\r\n");
delay_ms(1000);
}
}
}

Somebody explain me this programm because I don't understand it, and I want to reading de serial numer of the ibutton

Thanks
