Actual status of port for ESP32

Christmas time is comin soon.
That's a good time to report actual status of Espruino on ESP32.

• ESP32 tree in Espruino on github
  
• standard Espruino compiled and got it running (@nkolban)
  
• WIFI handling added (@nkolban)
  
• SPI compiled with Arduino Sources (@nkolban)
  
• interrupt handling for gpios, to support setWatch (@jumjum123)
  
• switch polling of console to interrupt driven handling (@jumjum123)
  
• one wire implemented and tested with DS18B20 (@wilberforce)
  
• I2C compiled with Arduino Sources and tested (@wilberforce)
  
• ADC and DAC running with new driver for specified pins (@jumjum123)
  
  

No drivers are available for I2C and SPI in esp-idf yet.
Therefore we have to live with Arduino sources right now.
Esp-idf is under heavy construction.
Sometimes even a simple call of a function changes its parameter sequence.

Actual status of Espruino for ESP32 is

• available mainly for developer, it is extremly simple to build
  
• first docs are available on github under targets/esp32/doc
  
• needs testing, testing, testing
  
• waiting for driver for I2C, SPI, BLE, etc. etc. in esp-idf to replace Arduino sources
  
• PWM needs to be implemented
  
• expect surprises, like not linear ADC
