[SOLVED] so now what am I doing wrong (trying to use INTOSC)

[techristian]

so now what am I doing wrong (trying to use INTOSC)????

I HAVE NO CRYSTALS YET. So I'm using INTOSC. I'm not expecting the segments to make any sense at this point. I just want to display different patterns on a single DIGIT 7 segment display. I have set up PORTC to power it and I'm trying to drive it directly from PORTC without buffering to memory.

Right now, when I power up the PIC16F1784 NOTHING HAPPENS !

Ok I just noticed something here.

MY TRIS COMMANDS ARE GONE.

I put them in lines 34 and 35 but they don't show up in the disassembly.
TRIS 5 ;set PortA all outputs
TRIS 7 ;set PortC all outputs

TRIS 5 ;set PortA all outputs
TRIS 7 ;set PortC all outputs

Did you selected bank1 where it resides? Error level 302 gives an error if it not suppressed.

this was marked as solved

thanks though
