Post by thread:[PIC] Hex files

Hi Another question :) The config bytes are stored at address outside the flash address range, are these stored in the hex file and if so does MPLAB do this for you or do you have to add the config bytes to your assembler code and then it gets added to the hex that way.

You specify the config bits using the "__CONFIG" assembler directive. MPASM (which is called from MPLAB of course) will then put the config data at the correct address in the HEX file. The actual address used is depending on which PIC you are targeting (as you specified in the source code). Jan-Erik.

I don't know if MPLAB does it automatically since I never build inside the IDE. However, you should specify all the config bits in your source code anyway. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com
