Multiple pwm objects

[diogoviannaaraujo]

Hi,

pins/pwm module expose a object but if you create multiple instances of it they all share the same channel.

Maybe it could receive a optional channel option in constructor together with 'pin'.
Or maybe it could keep track of available channels in an varaible and get the next available.

Yes. We ran into this a couple weeks ago too. Apologies. Your analysis of the problem is exactly correct. We'll get a fix in place.

I have been able to make it work based on pulsecount implementation:

Just need to find the correct way to correctly destruct it

[diogoviannaaraujo]

I guess i got destructing to work.

I still have some doubts about why the use of the initialized variable and if we should use Port as the channel.

There is a fix for this committed now. It supports up to four channels by default. That can be adjusted up or down using the project manifest.
