help for simulation warning
PostPosted: Tue Dec 08, 2009 12:19 am     Reply with quote
When I simulate my code I find following warning.
iOPORT-W0002: Reading a port immediately after writing to it might be affected by any impedance loading the pin.

For this instruction
Code:

delay_cycles(_t2);
data = input_lcd();

When I select device 18f4685 then I'm not getting any warning
but when I simulate with dspic30f6010 I find this warning.

Anyone can help
Thanks

Your question is about the MPLAB simulator. You should ask your
question in the Microchip forum, or search their forum archives.

Here's the search page for the Microchip forum. Bookmark this page.

iOPORT-W0002

and press Enter and you will get several hits.

I already search on Microchip forum. They advise to use LATx.
How to use in ccs c compiler? I'm new for ccs c.

Initial I was work on 18f8720. Due to require more program memory I have to switch 30f6010a. I'm facing this problem when I switch over to dspic.
This is 1st time I'm using dspic, nothing know about this. I'm using graphical display 320x240. (sel1330 library code)
