I2C, save(), onInit(), Internal Error - issues

Thanks - someone else mentioned about the lack of info on onInit - I'll try and add it to the documentation.

Which command for I2C did you have to run in onInit? If you write I2C1.setup({scl:B6,sda:B7}); then Espruino is supposed to automatically remember that and run it at power on (even without onInit).
