I've given this a go. I found a 3 pin cable which connected to the
pins in the I2C connector.

The white cable connects to pin 1 in the connector which is data, the
black cable connects to pin 2 which is ground and the red cable which
is the clock. I've connected these to the bread board:

These then connect to the daughter board, Plus a +5 and Ground to
power the board.

These connect to the respective Data Ground and clock (top left) and
+5, ground connect to the board to power it (bottom right). The dip
switches are set to 00, which sets the IC2 address to 0x50
The display then lights up when the power is connected.

I now write the following program to send the command to switch off
the back light:
Dim screen As oI2C
Sub Main()
screen.Node = 0x28 ' 0x50 divided by 2
screen.Mode = cv7Bit
screen = 0x28
End Sub
Unfortunatly nothing seems to happen. Any ideas?
Thanks,
Jas
