I think this has to do with the fact that even if you use a PORTD command followed by a PORTB command, you are still setting the eight pins in two steps. So, if i was going quickly and writing data from one register to another, then there was sometimes in certain circumstances data which was written to the wrong register -- because the PORTB command would have set the register and the PORTD command would have set the data. That's a guess though, because i couldn't track down the exact problem. But these issues are fixed with the addition of the two oct flip flops. <BR/><BR/>cheerio,<BR/><BR/>sebastianSebastian Tomczakhttps://www.blogger.com/profile/12712567577323498804noreply@blogger.comtag:blogger.com,1999:blog-23217409.post-1922811003551338042008-01-27T00:43:00.000+10:302008-01-27T00:43:00.000+10:30Excellent information, thanks!!!

It does make the circuit and the code simpler and more logical, and I know the parallel port circuit that you drew from already had them in there. Is there any other reason? Thanks again!<BR/>rahjirobhttps://www.blogger.com/profile/12579358764903509919noreply@blogger.com
