The version 2 of the IRIS spectrometer is works very well...

I use a number 13 grating from ocean optics.... since I'm only interested by the visible light wavelength, I plan to change the gratings...

I also plan to produce a second PCB with some IOs to be able to synchronize the acquisition with other subsystems.

But, well, I can say my main goal is complete ! ( github file will be updated asap )
