Post by thread:[PIC]: ICD and modify window

Hi! I'm trying to use modify window with ICD. I want to change RETLW 0 to RETLW 6. Opcode is changed in ROM window, but when I single step through program, it always returns 0 in w. Is this function supported in ICD? What about the stopwatch? Regards, Samo -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

I don't know anything about the ICD, but I don't see how it could change one location in program memory without erasing it all and re-writing it with the change. Given that, just change the source code and reload the resulting binary into the chip. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!

RETLW is an opcode meaning return with a literal in w. To change the literal value you have to change it in your program and reprogram the chip. Modify window is to change the value in RAM registers, not program memory. No stopwatch in ICD, only MPSIM. -- Quentin spam_OUTqscTakeThisOuTiptech.co.za http://www.iptech.co.za -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
