Post by thread:[PIC]: lost info on tristating pins

Somewhere...I had my answer and now I can't find it again. I need to tristate output pins as the code is running....if I recall there is something to do with using the TRIS command, but I thought it was related to the entire port and not just bits. I need to basically talk to one bus, but with two pins, so can't have them on at the same time or else contention. _________________________________________________________________ MSN Photos is the easiest way to share and print your photos: http://photos.msn.com/support/worldwide.aspx -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

All the PIC manuals are on line, so you can always refer to them when you lose yours. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

>there >is something to do with using the TRIS command, but I thought it was related >to the entire port and not just bits. It's bits. TRIS sets a register, at the same address as the port but in a different bank, and each bit corresponds to the same bit in the port register but controls direction instead of data.
