  I tried to use I2C1.setup({scl:D16, sda:D15})... PD16 and PD15; P16 and P15; PB6 and PB7...
  these values result in an error:

  Uncaught ReferenceError: "PIN" is not defined

  where PIN is D16, PD16, P16, PB6...

  Hi!

  I have chinese copy of Maple Mini with Espruino firmware 1v85.134. I'm trying to connect the LCD HD44780 with I2C (PCF8574T) and get and get the error :(

  Wiring LCD -> Maple Mini:
  GND -> GND
  VCC -> Vcc
  SDA -> PIN 15 (I2C1 SDA)
  SDL -> PIN 16 (I2C1 SDL)

  Code:

  I2C1.setup({scl:B6, sda:B7});
  var lcd = require("HD44780").connectI2C(I2C1);
  lcd.print("Hello World!");

  Error:
