you’ll only need a Keyspan serial adaptor, no Virtual PC, no
integrated BasicStap reference, syntax highlighting, all very well done!
if you’re headed for more power, and more choice of mcu’s for less cash
– and if you don’t fear the Terminal application – there’s also an
All-Mac-Way to program Atmel AVR Controllers in C, using open source
It was a bit of a headache to get it all running, but now works very
well. We’ve documented it here: http://www.anyma.ch/research/articles/avronmac.html
we write code in BBedit or Xcode, then compile it in the terminal and
flash the processor from the terminal, using an Atmel STK500
there’s even ways to do it without a dev board, but we didn’t have
time to document it yet.
