There are some GPLed USB frameworks laying around, my faworite is http://openprog.altervista.org/USB_firm_eng.html. It works fine, but using it for create a bootloader with sdcc is a bit pointless becouse SDCC generate a bigger final code than C18. This is a simple test compiling usb firmware from above link: sdcc: Flash usage: 13704 bytes C18: Flash usage: 8797 bytes Marico 2013/3/29 Luis de Arquer <dea...@gm...>: > I am starting a project on a pic18f2455 using USB, and I was trying to > find any library that I could use off the shelf with sdcc, if any -I > used ccs compiler in the past. > > I found one from an article published in nuts&volts, and also a port > from c18 to sdcc, but it looks like neither has been updated in the > last 6 years.
