Timer frequency minimum is 5 Hz?

[Saran]

Hi,

>>> from machine import Pin
>>> from machine import Timer
>>>
>>> tim = Timer(1, mode=Timer.PERIODIC)
>>> tim_a = tim.channel(Timer.A, freq=4)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ValueError: invalid argument(s) value
>>> tim_a = tim.channel(Timer.A, freq=5)
>>>

So, it's impossible to set frequency to a number lower than 5 (Hz). Is that really a feature?

I'm not familiar with the HW, but it may just be a limitation due to the source frequency, prescaler, and timer width.

Probably the timer width need to be set to 32 bit. I am working on the docs, will push later today. BTW, timers, are not fully tested because that part of the API wasn't clear yet, so don't expect everything to work there. It sucks, I know, hope to address it soon.

No prob. I'll use sleep in the meantime...
