3.1 Using
the
I
2
C interface of the 10-pin header
Select the I
2
C interface by sending the command from the DLL, as mentioned in the DLL
help file. After this, the board is ready to be used in I
2
C mode. The section below explains
how the tool and its features behave once selection has been made using the DLLs and it
also explains how the hardware setup is to be done.
shows the interpretation of
the 10-pin header when it is configured in I
2
C mode.

Steps for making the hardware connection
To use any I
2
C based slave with the IBU UI tool, you need to make the connection for
jumper J1, as shown in
●
The SCL (synchronous clock line), SDA (serial data), and GND (ground line) should be
connected to the corresponding lines of the daughter board for I
2
C communication
●
VDD (power supply line) of the two boards should be connected if the daughter board
is to be powered using the IBU UI tool
●
The GPIOs of the IBU UI tool and daughter board can be connected or left
unconnected as per user requirements
●
As shown in
below, the SDA and SCL line of the interface is already pulled up
to 3.3 V through a resistive pull-up of value 4.7 k
Ω
.
