DAC on ESP32 (use dacWrite)
PWM on ESP8266

Does the code work for ESP8266 as it is currently?
I tried to compile and run on an ESP8266 nodemcu (2.4.0 library), using GPIO 3, along with a simple transistor amplifier. I seem to only get random tones coming from the speaker.
That was the intention but I haven't been able to make it work with ESP8266 yet.
The ESP32 1-bit DAC is better but still not as good as the AVR.
Hopefully I will have some time to look at this over the summer.
OK ESP8266 should work now. I've tested it with a Wemos Mini D1.
