Anyone got any ideas on how/when pwm could be available?

Cheers!

- Thu Apr 30, 2015 6:35 pm #16139 According to git Ref #1, it has only one hardware PWM source, but another article Ref #2 mentions three possible sources (pins 12, 13 & 15). The git article also mentions possible issues with software PWM & WiFi connectivity, no mention is made of this in the second article... (I only scanned the articles briefly and may have picked up things wrong)...

Ref #1: https://github.com/esp8266/Arduino
Ref #2: http://tech.scargill.net/esp8266-pwm-on-one-output/ & http://tech.scargill.net/esp8266-tidy-pwm/

I would be very happy with one hardware PWM pin, up till now I didn't think it had any. Always thought I'd have to implement software PWM it the need arose...

I find it stranger that it mentions only one pwm source or even three as I also have 4 pins giving pwm under nodemcu
