- Mon Apr 18, 2016 8:46 pm #45753 I've been using NodeMCU (Lua) with PWM and I couldn't get PWM frequencies higher than 100hz.
I don't know if this is a hardware limitation (esp8266) or a framework limitation (nodeMCU).

so, my question is: is possible to get higher PWM frequencies using Sming? I don't mind sacrificing some range bits (from 10bits to 8bit for example) in order to get higher frequencies.

Thanks!

[edit. Sorry - as per Martin, I am an idiot for not reading. As punishment i will try to find an answer. Might take a while tho. Again, sorry.]

He asked :

- Thu Apr 21, 2016 10:24 am #45931 yes, I assumed that by using Sming (instead of NodeMCU) we could have more control, and perhaps trigger the PWM faster... but I don't know if that is possible.
Any idea? thanks.
