*lots* of stuff .. :) - got PWM working! also, i didn't make a note of it in the *.md file, but Waveform Generation Mode 15 for fast PWM wasn't working right (well.. wasn't working how i expected it to). i misinterpreted what the modes were doing, partially (haha, or all-ly?) because i didn't read the description of fast pwm thoroughly enough... in any case, all the information's in the datasheet, and it's actually not terribly long. i'm not sure how to correctly use Mode 15 yet, but i think i'll leave it alone for now, since Mode 5 works as expected, and i think what the datasheet says about *that* makes enough sense to me for me to be content for the moment.

checkin before deleting the debug code; almost ready for first beta! - simple bug fix in kbfun_press() and kbfun_release() - no longer check for previous init() in the mcp23018 functions; something would happen when i tried to read from it, sometimes, when it'd been unplugged or stoped some other way, and it would hang - and the only thing that would make it better was running the test_twi_2 function (a series of writes, with stops after each). so now mcp23018_init() is a series of writes, with stops after each. it doesn't take appreciably longer to run... maybe it should be looked into later though. - changed the main() loop a little

*lots* of stuff .. :) - got PWM working! also, i didn't make a note of it in the *.md file, but Waveform Generation Mode 15 for fast PWM wasn't working right (well.. wasn't working how i expected it to). i misinterpreted what the modes were doing, partially (haha, or all-ly?) because i didn't read the description of fast pwm thoroughly enough... in any case, all the information's in the datasheet, and it's actually not terribly long. i'm not sure how to correctly use Mode 15 yet, but i think i'll leave it alone for now, since Mode 5 works as expected, and i think what the datasheet says about *that* makes enough sense to me for me to be content for the moment.
