Problem with module ILI9341

@MaBe, if you want to use the HW SPI, do you still need to create one with new SPI()? Can you not just use the SPI1? SPI1 - all uppercase - is defined in ESP8266 (just checked0). var SPI1 = new SPI() may mess with that. If you want to create the SW SPI, I'd - by my gut to stay way for sure from trouble / interference - use spi = new SPI(); to not mess with SPI1...

>SPI // <--- entered in console
=function () { [native code] }
>SPI1 // <---
=SPI1
>SPI1.setup() // <---
=undefined
>var s = SPI1; // <---
=SPI1
>SPI1 = new SPI(); // <---
=SPI: {  }
>SPI1 === s // <---
=false
>SPI1 // <---
=SPI: {  }

Lines 5 and 14 and 11 show that you get new objects... and loose the HW SPI, I guess... do you? May be it just looks on the JS level that way, but not under the hood where it is created before JS takes place.
