dallas ibutton to pics

[Bosse]

Still problems with searching and get the right speed to see if an DS1990A is authorized (stored in EEPROM - 24LC65) Hope to could check about 50 iButton in EEPROM fastest possible. Tried to do a binary search, but have not succed to find a code that works, I'm quit new to program microcontrollers. Write my programs in PICBASIC PRO. Using a PIC16F628, 20 Mhz, going to change to a PIC16F876 with more RAM. Very greatful for all help I can get.

Can you post the code you have now for the searching?

Also the part that stores the keys in EEPROM.

Have sort them upon storing new key or deleting one?

P.S. Thanks for the wishes.
