4.1 Fm+ development board and WIN-SPIUSB software
The OM13524 is a daughter card to the OM13260 Fm+ I2C bus development board with
SPI driver which is part of the Fm+ development board kit (OM13320). You may
download the software, user manual, and find ordering information at the NXP web site:
http://www.nxp.com/demoboard/OM13320.html#documentation
The Win-SPIUSB software from The Boardshop runs on Windows 98SE, ME, 2000, and
XP and is compatible with any PC hardware having a minimum of a Pentium processor
and an USB port. The software allows the user to select one of the SPI-bus driver from a
menu and also provides a Universal mode (SPI Expert mode) to allow users to create
their own SPI-bus commands with the same SPI-bus devices.
4.2 OM13524 connection to Fm+ I2C bus development board
The OM13260 Fm+ I2C bus development board should be disconnected from your PC
before connecting the OM13524 PCA9745B demo board on to it. The OM13524 board
has a 9-pin male connector (CON1) that connects to the 8-pin male connector (CN16) on
the Fm+ I2C bus development board using six jumper wires as shown in the
Fig 1
.
