Having just purchased a Netduino Plus 2 and ported some existing code from my Plus 1 that uses PWM, I was initially stumped by why it wouldn't work. I went down a blind alley using SecretLabs.NETMF.Hardware.PWM, thinking that perhaps I needed to use that instead. In the end though, I discovered that I just had to call PWM.Start(), which wasn't necessary before. What gave me the tip-off was looking in the source code, I noticed it was calling PWM.Start() internally, so in that sense the class was useful, but I can't really see a reason for it to exist since it seems to be a poor relation to the equivalent in Microsoft.SPOT.Hardware.Pwm.

 

So what is this class for? Is this some sort of legacy class, or am I missing something?

Best regards,

Hi Tim,

Great question. The SecretLabs PWM classes existed before NETMF had integrated PWM classes. We provide them as optional add-ons for backwards compatibility with older code.

Ah, that makes perfect sense, thank you Chris.

 

I wonder, would it be worth applying the [Obsolete] attribute to this class as a signpost to use the newer classes in .net MF?

 

Best regards,
