Hi JPMontero

 

I have Galileo and the Adafruit LCD shield that you mentioned (http://www.adafruit.com/products/716 ). I followed the instructions you  provided and still I am not able to see any text on the LCD.

I did the following:

- Updated the LiquidCrystal Library as per Mikal.Hart post: Galileo LiquidCrystal Library Fixes

- Changed the I2C jumper to the second and third pin.

- Modified the library provided by Adafruit to make it compile with the Galileo. Modified files Adafruit_MCP23017.cpp and Adafruit_RGBLCDShield.cpp as instructed.

 

With this changes, I was able to compile and upload the code to Galileo, nevertheless the LCD does not behave as expected, it seems to be refreshing but only displays squares. Im using the "hello world" explample from Adafruit.

 

hope you can help
