Adafruit CharLCD and keypad kit help

Sat May 07, 2016 8:57 pm

Hi, using the Adafruit CharLCD Plate and keyboard, I'm making Adafruit's wifi radio. https://learn.adafruit.com/pi-wifi-radio/overview When I try to run the command

Code: Select all

sudo python Adafruit_CharLCDPlate.py
I get this error

Code: Select all

Traceback (most recent call last):
  File "Adafruit_CharLCDPlate.py", line 467, in <module>
    lcd = Adafruit_CharLCDPlate()
  File "Adafruit_CharLCDPlate.py", line 106, in __init__
    self.i2c.address, self.MCP23017_IOCON_BANK1, 0)
IOError: [Errno 5] Input/output error
Does anyone know what is happening?
People who say times instead of multiply shouldn't be around.

Yes, probably, you haven't wired it up properly.
