Hi Jim So I looked at a variety of other i2c based LCD codes (there seem to be lots for the Raspberry Pi), but I didn't like them. So you can try mine.
You can do the following on the BBB: git clone https://github.com/dhylands/python_lcd.git cd python_lcd sudo pip install -e . sudo python lcd/i2c_lcd.py Running i2c_lcd.py runs some test code which puts some stuff up on the LCD, and after 3 seoncds shows the current data and time and then cycles through a variety of backlight/display on/off combinations. I used a 3.3v to 5v level shifter. I wound up using smbus directly rather than the Adafruit_I2C (but installing Adafruit_I2C will install smbus) I threw some photos together here: https://picasaweb.google.com/115853040635737241756/PythonI2CLCD?authkey=Gv1sRgCLyZoJ3_uPjiXA# Coming from the BeagleBone Black the wire colors are: Black: P9-1 GND Red: P9-3 3.3v Orange: P9-5 5v Yellow: P9-19 SCL White: P9-20 SDA And the colors going to the LCD are: Black: GND Red: 5v White: SDA Yellow: SCL -- Dave Hylands Shuswap, BC, Canada http://www.davehylands.com -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
