Damien George	d29b709642	stm32/timer: Enable ARPE so that timer freq can be changed smoothly. The timer prescaler is buffered by default, and this patch enables ARPE which buffers the auto-reload register. With both of these registers buffered it's now possible to smoothly change the timer's frequency and have a smoothly varying PWM output.	2017-09-25 15:25:08 +10:00
Damien George	d7cd1d2027	stm32/timer: Make pyb.Timer() instances persistent. Prior to this patch calling pyb.Timer(id) would always create a new timer instance, even if there was an existing one. This patch fixes this behaviour to match other peripherals, like UART, such that constructing a timer with just the id will retrieve any existing instances. The patch also refactors the way timers are validated on construction to simplify and reduce code size.	2017-09-13 16:20:42 +10:00
Damien George	01dd7804b8	ports: Make new ports/ sub-directory and move all ports there. This is to keep the top-level directory clean, to make it clear what is core and what is a port, and to allow the repository to grow with new ports in a sustainable way.	2017-09-06 13:40:51 +10:00

stm32/timer: Enable ARPE so that timer freq can be changed smoothly.

The timer prescaler is buffered by default, and this patch enables ARPE
which buffers the auto-reload register.  With both of these registers
buffered it's now possible to smoothly change the timer's frequency and
have a smoothly varying PWM output.

Prior to this patch calling pyb.Timer(id) would always create a new timer
instance, even if there was an existing one.  This patch fixes this
behaviour to match other peripherals, like UART, such that constructing a
timer with just the id will retrieve any existing instances.

The patch also refactors the way timers are validated on construction to
simplify and reduce code size.

This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
