Damien George	f042d7a4d7	stmhal: Fix edge case for timer PWM of 100%. ... Also improve precision of calculating PWM percent in integer mode. Also update teensy with edge case fix.	2014-09-29 14:15:01 +01:00
Dave Hylands	39296b40d4	Fix timer overflow code. ... 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.	2014-09-27 19:40:37 -07:00
Damien George	e8ea0724da	stmhal, timer: Factor code to compute PWM percent; improve 32bit case. ... Also do the same for teensy timer code.	2014-09-25 15:44:10 +01:00
Dave Hylands	53d5fa641f	Add pulse_width_percent to teensy. ... Fix stmhal and teensy print routines to report actual prescaler an period. Fix teensy build to use soft-float Add USE_ARDUINO_TOOLCHAIN option to teensy build	2014-09-23 23:19:36 -07:00
