I wanted to make sure everyone knew about the new bootloader from Microchip which supports both 16and 18 series flash chips. http://www.microchip.com/1010/suppdoc/appnote/all/an851/index.htm I found out through the newest circuitcellar contest. I haven't gone over it in detail, but it supports autobaud detection in the 18 series chips, uses the uart, and appears to be pretty full featured. It's all in assembly, so no C compiler needed (as you might get with many of their other app notes) There's no MPLAB support, but I wouldn't be surprised to see it down the line... (Well, not *too* surprised... :-) ) -Adam -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.
