Hi
My secular star of David has 16 arms each with 8 hi-brite leds so the easy way (i think) is a matrix which requires 24 I/O pins. Whilst I could use some other Ports it would be nice the way I have set up the 44 pin demo board to use Port A. Two questions now arise:
1. Can I use RA6 and RA7 as outputs if there is a xtal connected across them ( do not know what the DC characteristics of a xtal are)
2. How the devil do I program the 16F887 so that those two pins are available as outputs. I understand that I have to set up the configuration word (register 1) so that bits 2 -0 are 100 which should set the two pins as available for I/O (subject to item 1 ((above)) But what is the syntax for doing this ? I see no rference in the Picbasic manual (or anywhere else) to this. I have looked at examples but cannot figure it out from that. Any advice on this would be appreciated
Cheers
