Install Guide for OM13320
1. Introduction
The Fm+ Development Kit (OM13320) is intended for several different tasks; from a hands-on
introduction, understanding, and use of the I2C (Inter-Integrated Circuit) Bus, to I2C device evaluation,
and as a simple product demonstration platform (for trade shows and sales pitches).
The kit has a core Printed Circuit Board (PCB) assembly, and three add-on PCBs. Other PCBs are
available for advanced use or to support newly released I2C components as they are introduced to the
market.
The Fm+ Development Kit (OM13320) is supported by a Graphics User Interface (GUI) software
program that runs on a Personal Computer (PC) under the Microsoft Windows 7 Operation System. In
some uses the GUI is not required, and the Fm+ Development Kit (OM13320) can be run as a
standalone demonstration, requiring only an external power adapter (not included).

3. Fm+ Development Kit Quick Tour
The kit is very flexible and the modular design is intended to allow expansion as new I2C devices are
released by NXP. Beyond the kit is the requirement to connect a computer that runs the NXP GUI
software. While it is possible to operate the kit without a computer, using only a suitable DC power
supply, the computer is required to install or update firmware on the Fm+ Development Board
(OM13260).

Note: An NXP specific USB driver is required on the computer for the NXP GUI to operate correctly.
3.1 NXP GUI and Standalone (“Trade Show”) Modes
When not connected to a computer the Fm+ Development Board (OM13260) operates as a standalone
system, but still requires the installation of firmware on the board.
The supplied NXP software package includes two different firmware programs, see table 3.1.

The “Trade Show” mode activates the LEDs on the Fm+ Development Board (OM13260) and also on
the optional GPIO Target Boards (OM13303) if attached. This “Blinky lights” are a suitable
demonstration for Trade Shows.
3.2 Kit Contents
Before using the kit for the first time, please familiarize yourself with the various components, as
shown in Table 3.1 See figure 3.1 and figure 3.2
Note: Each PCB assembly is shipped in an anti-static bag.
After the first time use these may be abandoned to simplify future storage.

3.2.1 Box Contents
The Fm+ Development Kit (OM13320) contains four PCB assemblies, cables, and loose hardware.
These should be retained in the box for future access. Depending upon the desired use some of the
PCB assemblies may be attached to each other, either by plug connection or by ‘stacking’ the GPIO
PCB assemblies above the Fm+ Development Board (OM13260), using the supplied ribbon cables and
hardware.
3.3 Supplied Printed Circuit Board (PCB) Assemblies
There are four PCB assemblies in the kit. Each has a specific function, not all of them are used at the
same time.
3.3.1 Fm+ Development Board (OM13260)
The large PCB, Fig 3.3, contains two separate I2C Bus structures, together with supporting circuitry.
Each bus has a Bus Master, one or more Bus Slaves, and user options to change the Bus Voltage and
Bus pull up resistors. Adjusting these changes the operation of the buses, to suit various goals. In
addition the two buses may be linked together to operate a one I2C Bus structure. This can be done
with a two-wire jumper (supplied) or the Bus Buffer Board OM133998 (supplied) See figure 3.5. Four
identical ports provide access for add-on boards that contain additional I2C devices.

4. First time setup: Fm+ Development Board Kit (OM13320)
4.1 Before You Begin
To use the Fm+ Development Kit (OM13320) for the first time requires some hardware set up and
installation of both firmware (on the Fm+ Development Board OM13260) and software on the
attached computer.
The following four steps must be completed:
1. Install Jumpers on the Fm+ Development Board (OM13260) (see section 4.3)
2. Install the USB Driver on the computer to be used with the kit (see section 4.6)
3. Install Firmware on the Fm+ Development Board (OM13260) (see section 4.7)
4. Install the NXP GUI Software on the computer to be used with the kit (see section 4.8)
There are two distinct operating modes each requires different firmware on the Fm+ Development
Board (OM13260).
It is recommended to install the “Trade Show” mode first, as this is an easier learning curve. Then
remove and replace it with the NXP GUI Firmware.
4.2 First time set up of the Fm+ Development Board (OM13260)
Several jumpers must be installed before using the Fm+ Development Board (OM13260) PCB. The on
board microcontroller (MCU) must contain the appropriate firmware. There are two distinct
applications (“Trade Show”mode and GUI mode) which require different firmware.
To replace the firmware requires the connection to a Personal Computer (PC) running Microsoft
Windows 7/64 Operating System and a USB port
4.3 OM13260 Jumpers
The Jumpers and their function are shown in Table 4.1 Using figure 4.1 and the table data install the
jumpers.

4.5 OM13260 Mounting Hardware
To prevent damage to the table surface it is recommended that metal hardware (supplied in the kit) is
installed in the four mounting holes. This raises the PCB assembly about 6mm. See figure 4.3
Fig 4.3 OM13260 Mounting Hardware
Note: Save the completed Fm+ Development Board, now install the NXP USB Driver
4.6 NXP USB Driver Installation
The Win7/64 OS (Operating System) will attempt to auto-install a driver when the Fm+ Development Board is
attached by USB for the first time. However, this is not the required driver to operate with the NXP GUI. Most
likely you will see the error message shown in Figure 4.4.
The following four steps must be completed:
1. Attach the completed Fm+ Development Board (OM13260) to the computer via USB cable
(supplied in the kit)
2. Using the Device Manager, remove the default USB driver
3. Select the driver supplied in the NXP GUI distribution

This completes the installation of the required driver. Check again with the Device Manager entry, which
should match figure 4.11.
Note: The actual COM port number is not important, and will vary depending upon other port assignments
in use on any particular machine.
4.7 Fm+ Development Board (OM13260) Firmware
Depending upon the intended operation of the Fm+ Development Board (OM113260) one of two
different firmware programs must be installed. These are summarized in Table 4.2.
Table 4.2 Supplied Firmware
FM+DevelopmentBoard V03_00.bin
19kb
Standalone_trade_show_FM+_DEMO.bin
7kb
When operated with the NXP GUI the Fm+ Development Board (OM13260) requires a different
firmware to that used for the “Trade Show” Mode (described in section 4.1). Repeat the steps given in
section 4.7 to install the GUI Firmware on to the Fm+ Development Board (OM13260) MCU.
4.7.1 “Trade Show” Mode
A popular use of the Fm+ Development Board (OM13260) kit is for publicity and promotion of the I2C
Bus products from NXP. A version of the firmware provides “Blinky Lights” on the Fm+ Development
Board (OM13260) PCB, and the optional attached GPIO Target Boards OM13303.
Note: This mode does not require a computer connection. The NXP GUI will not work while the
firmware on the Fm+ Development Board (OM13260) is set to “Trade Show” mode.
Note: To restore operation with the NXP GUI running on a computer attached by USB cable, the
firmware on the Fm+ Development Board (OM13260) must be reset from “Trade Show” mode by
installing the correct firmware. (See section 4.8).
Once this is installed the Fm+ Development Board (OM13260) will no longer work with the NXP GUI
(running on an attached PC). Each time the Fm+ Development Board (OM13260) is powered up the
demo program will run. No USB connection or computer is required, except for an external DC power
supply.
4.7.2 NXP GUI Mode
When the Fm+ Development Board (OM13260) is used with the NXP GUI the correct firmware must be
installed on the MCU. (See section 4.8).
Note: This mode does require a computer connection. The NXP GUI will only work when the

Development Board (OM13260) is connected.
Note: To restore operation as a “Trade Show” demo, the firmware on the Fm+ Development Board
(OM13260) must be reset to “Trade Show” mode by installing the correct firmware. (See section 4.8).
4.8 OM13260 Firmware Installation
Access to the on board MCU firmware is made through the USB port (CN5). The MCU is also accessible
from the JTAG connector (CN19) should it be necessary to recover from a “bricked” board (not very
likely as the MCU boot-loader code is in protected memory).
1. Connect a USB cable from the PC USB port to CN5.
Note: Two green LEDs are on (D4 for VUSB and D5 for 3V3)
2. Install the ISP (JP6) jumper to put the MCU into In-System Programming mode
3. Install and then remove RST (JP4) jumper to reset the MCU
4. The MCU will enumerate on the PC as shown in Fig 4.12 and Fig 4.13
5. Delete the file on the MCU (size may vary - up to 32kB)
6. Copy the new firmware file to the MCU as shown in Fig 4.14
7. Remove the ISP (JP6) jumper
8. Install and then remove RST (JP4) jumper to reset the MCU
Note: The green LED (D8) is blinking. This is the ‘Heart Beat’ to show the MCU is alive

5. Fm+ Development Board (OM13260)
The Fm+ Development Board (OM13260) PCB assembly is self-contained, requiring only DC power to
operate. Depending upon the firmware installed on the Fm+ Development Board (OM13260) it can
also operate with a connected Personal Computer (PC) via a USB cable.
The modular design of the kit and this board in particular allows accessory boards to be easily
connected.
5.1 Theory of Operation
Fig 5.1 Fm+ Development Board Bus Structure
An I2C Bus requires a Master and one or more Slaves. The two bus signals; clock SCL and data SDA, are
Wired-OR and require pull ups to a DC power supply. Two similar but separate I2C busses each support
one Master and at least one Slave device on the board. The two busses may be linked by either a Bus
Buffer Board (OM13398 supplied in the kit) or a wire jumper, at the Port E connector (CN12).
The signals from both busses are available simultaneously at each of four connectors, Port A through
Port D (CN1 through CN4 respectively). These are intended for attachment of accessory Daughter
Cards, which will be made available as future I2C devices are released.
The size of the pull up resistors can be changed by moving shorting jumpers (JP1, JP2, JP11, and JP12),
providing selection of ‘Low’ ‘Med’ and ‘High’ resistor values scaled to the Fm+ I2C Bus drive strength.
When both busses are joined by a jumper wire the pull ups are effectively in parallel, and have one half
the stated resistance values.
Operating voltage of the I2C Bus depends upon the shorting jumpers (JP13 and JP23) that select either
3.3V or 5V connected to the pull up resistors. Compliant I2C devices can tolerate 5.5V (max) regardless
of the device operating voltage.
Each bus has a GPIO eight bit Slave device (PCA9672, IC10 and IC20), and Bus 1 also has an LED Driver

sixteen channel device (PCA9955, IC6). All sixteen outputs are connected to LEDs, for visual indication.
The eight bit GPIOs require connection of GPIO Target Boards (OM13303, supplied in the kit) to both
indicate the output using eight LEDs and allow user input from eight push switches.
An NXP LPC1343 Microcontroller (MCU) serves as both the Bus 1 Master, and the USB link. The
firmware on the MCU can be replaced by the In System Programming (ISP) mode, with data sent over
the USB link (CN5).
Bus 2 has a Parallel to I2C Bus Controller device (PCA9665, IC6), which is to be driven by an optional
NXP LPC Xpresso module (not supplied). That Module is also an I2C Master and connected to Bus2.
Note: Although the Bus2 has more than one I2C Master only one is active at any time.
The remaining circuitry is to support the I2C devices, and provide communications with the PC over a
USB link.
The main operating voltage on the Fm+ Development Board (OM13260) is 3.3V supplied from a linear
regulator (IC1). Some circuits and the optional I2C Bus pull ups may run from 5V derived either from
the USB host (typically a PC) or an AC-DC power supply (not supplied in the kit). The actual voltage is
seldom five volts, due to cable losses, plus an additional drop in a series connected diode used to OR
the two inputs. Whichever has the highest voltage has priority.
A shunt Zener diode (6.2V) protects the board from reverse polarity and over voltage at the DC Power
connector (CN6).
To aid in understanding digital signal levels on the board two “logic probe” circuits are provided. These
are buffered LEDs (Green, D6 and Red, D7) which light if their respective inputs (CN11) are grounded.
Two global digital signal nets, called INT (interrupt) and RST (reset) connect all I2C devices on the board
and also the Port A –Port E Daughter Card connectors. These are also connected to the Master (MCU,
IC5) on Bus 1, the Master (Bus Controller, IC4), and the LPC Xpresso module.
Note: The I2C global Reset is not the same as the MCU Reset. Resetting the MCU will only reset the
I2C Bus if the MCU Firmware is intended to create a global reset.
The test points provide monitoring of Interrupts (usually generated by I2C Slaves) and software reset of
Fm+ class I2C devices that have that feature.
Additional buffered LEDs are provided (D19, RST and D20, Interrupt) on the Fm+ Development Board
(OM13260) for visual indication.
Various MCU and LPC Xpresso signals are made available through additional connectors. These include
a serial Port (CN7) with EIA232 voltage level translation (IC2) and SPI Bus signals (SP0, CN9 and SP1,
CN8) from the LPC Xpresso module, together with SPI Bus (SP2, CN16) from the MCU (IC5).
A prototyping area is provided for solder connection of components that may be required by an
application circuit beyond this board’s design. Power supplies and other signals are readily available.
On the Fm+ Development Board (OM13260) V3.0 there is an LED Blinker device (PCA9901, IC3) and LED
indicator (D10), while not strictly an I2C device, as it uses a one wire protocol, it belongs to the NXP I2C
