Hi, I've been an observer of the PICLIST for some time and am impressed with some of the valuable responses given to questions asked. Forgive me if this question ha s been answered before, but I have a project in mind using a 16F84. I am interst ed in using a 93LC56 Serial EEPROM but am running out of pins. There are other w ays of freeing an extra pin, but for simplicity, I was hoping that I could conne ct the Data In pin to the Data Out pin. The data sheet indicates it can be done, but that there is the possibility of a 'bus conflict'. This is where I got a bit lost. Has anyone used this approach an d, if so, what do I need to watch out for? Thanks in advance for any responses. Murray ,-._|\ Murray Neill / Oz \ Melbourne PC User Group. \_,--.x/ Australia v
