Hi all, I am new to PIC's and micros. I have an 18F252 with bootloader installed = on chip, set up for a 10MHz xtal. I am looking for a PC (winXP) host = program with which I can bootload files onto the chip. My understanding is that the bootcode on the chip is specific to a = certain frequency crystal as is the bootloader. Is this correct? I am having problems finding one that suits both the 18Fx52 chips and a = 10MHz xtal. I would also like to be able to use 4MHz and 20MHz at some = stage, is there a software that can adapt to different frequency = crystals? I would be grateful for any help anyone can offer, cheers Rich -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
