Fail to control Grove LCD with RGB Backlight on Sodaq Mbili
SeeedStudio 'Grove-LCD RGB Backlight' V4.0 connected on Grove I2C socket (12).
Downloaded Grove_LCD_RGB_Backlight-master.zip from seeedStudio on 23/5/2018 (24,7 KB)
Using only the example sketches from this library (e.g. setColor.ino, Cursor.ino, TextDirection.ino, ...)
All the example sketches include and "rgb_lcd.h"
Compilation performs ok
Upload performs ok
Running the sketches: No reaction of the LCD, only the backlight is continiously on, blue color
Any idea what could be the problem?
