In the bulleted list there are some mistakes: - libc should be: avr-libc - usip should be: uisp The author pointed out how difficult it is to use uisp on the Mac. The author should have gotten avrdude instead: http://savannah.nongnu.org/projects/avrdude avrdude is known to work under Linux, FreeBSD, Windows, and Mac OS X. And it's licensed under the GPL.

  Thanks missed those things.
  
  I hadn't seen avrdude. It seems very complete with all the bells and whistles. The only problem is it requires a parallel port. I had some very slight acquaintance with a USB <-> Parallel port device but never could get it working on the Mac. Perhaps others would work. I ended up rolling my own download program since I had the Delcom board. Not as nice as avrdude but pretty natural as I do this kind of thing in my (paid) embedded work.
  
  I will look into adapting the Delcom device into the avrdude program. I just did a build of it on OS X and found it does need a bunch of _ppi_xxxx routines which I guess is where you insert your parallel port drive routines.

  Read the avrdude user manual.
  - avrdude will use a serial port to use an STK500 or AVRISP programmer. It is known that you can use a USB->serial port convertor successfully on Mac (IIRC, Keyspan works).
  
  - On other platforms with using a parallel port, you should not have to change the avrdude source code. You can add a programmer to a configuration file.
  
  Also, for all things AVR, you should visit the AVR Freaks website at www.avrfreaks.net (no affiliation). It has an incredibly active community with several online forums including an AVR GCC Forum.
