Thanks.

Sorry about the spelling, I obviously read too much American.

I shall contact TI and IAR and see if I can get it at a lower price.

I downloaded TIMAC the 802.15.4 stack. I need to look at this a bit more closely, but I think there are libraries for which there are no *.c files. There is a components folder with sub folders with *.h and *.c, but 'some' of the extern function fwd definitions in the .hs have no definitions in a .c file.

Under a project folder with IAR example projects there are a couple of library files, so I am guessing that some of the source is available and some is not and is IAR comiler specific.
