Hi, I am using DS80C390 and using its port 5 pins to interface to seeprom : AT24C256 . Tini is supposed to read data on this serial prom. On the complete system ,there is PIC controller which is writing data on this seeprom. The clock and data pins are shared and only one will acess the seeprom at a time . This access logic will be controlled by another io pin handshake signals. Right now i am not able to read data form this seeprom. The PIC controller is not writng data on this . with respect to the hardware , what has been informed is the ground of tini and seeprom ground are diffrent. I guess ,this should be the problem. Is it correct ? Can anybody explain the pro and cons of such situation ? regards, sharmila _______________________________________________ TINI mailing list TINI-6tN4nzCoH/[email protected] To UNSUBSCRIBE, edit your profile, or see list archives: http://lists.dalsemi.com/mailman/listinfo/tini
