LCD para-pain in the Ar$$! Bad pins on bs2?

Archiver

Hey guys....just doing a pin by pin check of my outputs.

I do a:
out8 = 1
out9 = 1
out10 = 1
out11 = 1
out12 = 1
out13 = 1
out14 = 1
out15 = 1

and the only pins that go high are 14 and 15!! Is it possible I have
a bad stamp?? Or is something saved in memory somewhere not letting
this go high?

Thanks

The contents of the output latches are not reflected on the I/O pins
unless the pins are set to output mode. Try:

dirh = $FF
out8 = 1
out9 = 1
out10 = 1
out11 = 1
out12 = 1
out13 = 1
out14 = 1
out15 = 1

and see if that doesn't make a difference.


Regards,

Steve
