I need too high a rate for dithering. I didn't know the tools were free,
I have old Kiel and IAR JTAG debuggers that I bought a few years ago,
that just might work.
I'm a dinosaur, good as the compilers might be I still prefer assembler,
then any mistakes I make are my own, and, having been writing in
assembler for close to 40 years I think I write as fast, for the work I
want to do as I would in C and get more out of it. A lot though is to do
with feel, neither C nor C++ was designed for embedded systems, and I
think the methods used to kludge it all together are ugly. I think
Bitset and Bitclr are far more intuitive, for example, than any C
alternative I've seen.
I guess I'm just as comfortable in assembler as anything else.
