Also update teensy with edge case fix. 2014-09-28T02:40:37+00:00 Dave Hylands dhylands@gmail.com 2014-09-26T16:04:05+00:00 urn:sha1:39296b40d49b4b6b9373a80de67e017e540f1408 Teensy doesn't need to worry about overflows since all of its timers are only 16-bit. For PWM, the pulse width needs to be able to vary from 0..period+1 (pulse-width == period+1 corresponds to 100% PWM) I couldn't test the 0xffffffff cases since we can't currently get a period that big in python. With a prescaler of 0, that corresponds to a freq of 0.039 (i.e. cycle every 25.56 seconds), and we can't set that using freq or period. I also tested both stmhal and teensy with floats disabled, which required a few other code changes to compile. 2014-09-25T14:44:10+00:00 Damien George damien.p.george@gmail.com 2014-09-25T14:44:10+00:00 urn:sha1:e8ea0724da1b2fd6f6eb1cc99154072159fc2c8d Also do the same for teensy timer code. 2014-09-24T06:19:36+00:00 Dave Hylands dhylands@gmail.com 2014-09-22T05:40:42+00:00 urn:sha1:53d5fa641f322739ca372adcd1d4b53d5e2c0357 Fix stmhal and teensy print routines to report actual prescaler an period.
