Hi Jose

I stumbled upon this post with interest but I am using a different shield by Adafruit also a big promoter of Arduino UNO.

As described above I have UNO R3, DFR0009 which work perfectly together. I also have Adafruit ADA1141 data logger shield which also works with the UNO R3 when fitted on it's own…

As soon as I attach the DFR0009 LCD the ONLY thing I can do with the screen is turn the backlight ON/OFF by calling pin 10 HIGH or LOW, absolutely nothing written to the LCD using lcd.print(****); will appear…

Would you like to start this post rolling again please

Thanks

Darryl
