ICD & LCD

[Breuil]

I have problems when I want to use CCS LCD display routines (lcd.c).
I use too ICD2 (and soon ICD-U).
Is it possible to use together a LCD display (which uses B6 and B7 ports) and ICD (which uses too B6 and B7)?
Or do I have to change ports and so to modify CCS sources? (I hope no...)
Thank you.

This is a small part of the LCD driver

#if defined use_portb_lcd
#byte lcd = 6 // on to port B (at address 6)
#else
#byte lcd = 8 // on to port D (at address 8)
#endif

It is designed to be flexable with just a few defines.

Sorry, but I forgot to tell that I must use a 28 pins PIC, without portD, and I effectively used:

#define use_portb_lcd

So, can anyone tell me if it is possible to use together a LCD with portB AND an ICD (ICD2 or ICD-U)?

You can not use B6 and B7 for both ICD and LCD.

Finally I wrote modification on CCS's LCD.C, my LCD runs with B0 -B4 and C0, C1, and ICD on a 18F256.
