2016-01-29	stmhal: Add PWM capability for LED(3) and LED(4) on pyboards.	Damien George
	USB CDC no longer needs TIM3 (which was originally used for LED(4) PWM) and so TIM3 has been freed for general purpose use by the user. Hence LED(4) lost its PWM capabilities. This patch reinstates the PWM capabilities using a semi-generic piece of code which allows to configure a timer and PWM channel to use for any LED. But the PWM capability is only configured if the LED is set to an intensity between 1 and 254 (ie only when needed). In that case the relevant timer is configured for PWM. It's up to the user to make sure the timers are not used if PWM is active. This patch also makes sure that PWM LEDs are turned off using standard GPIO when calling led.off() or led.intensity(0), instead of just setting the PWM counter to zero.
2016-01-29	stmhal: Make TIM3 available for use by the user.	Damien George
	TIM3 is no longer used by USB CDC for triggering outgoing data, so we can now make it available to the user. PWM fading on LED(4) is now gone, but will be reinstated in a new way.
2015-07-22	stmhal: Allow ADC.read_timed to take Timer object in place of freq.	Damien George
	This allows a user-specified Timer for the triggering of the ADC read, mirroring the new behaviour of DAC.write_timed. Addresses issue #1129.
2015-07-21	stmhal: Allow DAC.write_timed to take Timer object in place of freq.	Damien George
	This allows the DAC to use a user-specified Timer for the triggering (instead of the default Timer(6)), while still supporting original behaviour. Addresses issues #1129 and #1388.
2014-06-30	Add timer_deinit and call it just before doing a soft-restart	Dave Hylands
	This fixes #733.
2014-05-03	Add license header to (almost) all files.	Damien George
	Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
2014-04-21	stmhal: Add Timer class: simple TIM control, incl callback on IRQ.	Damien George
	Simple but functional timer control. More sophistication will eventually be added, or for now just use direct register access :) Also added pyb.freq() function to get MCU clock frequencies.
2014-04-15	stmhal: Add ADC function to read data at a given frequency.	Damien George
	Reads ADC values into a bytearray (or similar) at a fixed rate. Needs a better name and improved API. Also fix up DAC dma function (which also needs a better name and API).
2014-04-02	stmhal: Add timer module; move servo PWM from TIM2 to TIM5.	Damien George
	As per issue #257, servo is better on TIM5 because TIM2 is connected to more GPIO.
