As I am new not only with Edison but with js as well , I would appreciate any comments on what I may have not modified correctly on the code.

When I run from node.js although the program seems to work with no problem, I do not get any message on the LCD. I believe that somehow the SPI is not selected.

When I run just a simple test js to blink the onboard LED that goes to pin13, it works fine.

Any comment or suggestion from you or anyone else is welcomed.
