Having problems with I/O ports F & G on 16F946

[manta_z]

I don't have this one in stock, but I would try

LCDCON = %01000000

Setting that bit did nothing.

But I found this out today after some testing.

If I add a micro second delay between any H-L or L-H output on those pins it works fine and no other pins act up.

So I assume there is some internal LCD element charge/time issue on these pins before the data state is valid?

Since any value below 4 micro seconds does weird things on pins and even reboots the pic from time to time.

I also added some delays in the setting of directions (tris) and other settings but that had no effect.

Does this make since, anyone else use LCD pins normally and not have this issue?

Can you post your code?

Are you writing to the whole port or some PORT bits here and there?
