Re: Tiny ARM Development

Thanks for the link to your book. I'll be ordering a copy later today.

I suppose that the biggest stumbling block I'm facing, to start with,
is my inability to find the sort of documentation that I am used to for
this chip. I've done extensive development with the AVR and Rabbit
processors, and both have excellent documentation of the sorts of
things like "Data Direction Register for I/O Port A is at memory
address XX," "Data Register for I/O Port A is at memory address XX,"
etc. Merely reading and writing to I/O ports, which I'm just
*assuming* are available on the chip, is proving no readily documented
task. I haven't even been able to find a detailed instruction set
list.

The power that this chip provides is what I need. I don't need it to
run an operating system, run multiple threads, or any such business.
It simply needs to read ports when an external interrupt is triggered,
and output on other ports the rest of the time (with some memory used
as a cache in between these operations).

Thanks again.
