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).
2. Key Features
I2C Masters:
Self-contained PCB with two independent I2C Buses
Bus 1: On card I2C MCU Master (NXP LPC1343)
Bus 2: NXP LPC Xpresso MCU module (not included), and NXP PCA9665 Bus Controller
USB Interface to on card MCU (for connection to a PC running the GUI software)
I2C Slaves:
General Purpose Input/Output (GPIO): PCA9672 (one each on Bus1 and Bus2)
LED driver, with 16 constant current outputs: PCA9955 (with four RGB and four White LEDs on
Bus1)
Accessory Sockets:
Connectors for up to four daughter cards, each providing power, Bus1 and Bus2 I2C signals
Connector for the Bus Buffer Board OM13398 (supplied) containing two PCA9617A Bus
Buffers
Connector for a third party I2C Bus logger or I2C Bus controller (Beagle and Aardvark, from
Total Phase)
I2C Buses:
I2C Bus Voltage; jumper select 5V (external) or 3.3V (on card 3.3V regulator)
I2C Bus Pull up Resistors; jumper select of ‘high’ ‘med’ or ‘low’ loading
Other Features:
SPI Ports; One for on card MCU, two more for LPC Xpresso
Serial Com Port; EIA232 with voltage level shifter and connection to the LPC Xpresso
LED Blinker; NXP PCA9901 one-wire with on card LED
INT (Interrupt) and RST (Reset) Bus signal monitor LEDs (buffered)
Logic Probe; Utility LEDs (buffered) to monitor signals by user jumper wire connection
External DC input (6V DC maximum)
Prototype Area; Uncommitted 8x8 100mil pitch tie points for end user component attachment
Test Points and Ground; for probe attachment to major signals
Connection of both I2C Buses together (supplied 2-wire jumper)
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).
