  Bitbanging like this is fine for synchronous protocols... but if you're trying to work with an async one like this one, there's just no safe way to do it in C unless your have a lot of leeway in your timing. Even if you get it to work today, there's no telling how a compiler update might change the instruction generation enough to change the timing and screw it up.

  I know it's cliché to tell people to go code in assembler but... this is where you do it, and why you do it. And it's easy. Seriously. These things are so simple it is not hard at all to learn how to code for them in asm. And it opens up a whole world of cool timing hacks you just can't do in C.

  I haven't done much microcontroller stuff recently, but here's a thing I wrote for an ATtiny somewhat recently. This kind of tight timing bit banging hack is just not possible to do reliably in C.

• New to photography. Will the sigma lens on this film 650D work on my 40D dslr? I.e. Will autofocus work
