The idea for the ChameleonARM platform was created when NXP introduced the new 32-bit ARM7 single-chip LPC23xx family with its rich set of on-chip interfaces for applications requiring various types of serial communications. |
| |
| The ChameleonARM board is also a tool for system developers who want to familiarise themselves with the LPC23xx family as a complete reference platform – with installed demo software showing both the processor power within the ARM7 environment as well as the communication interfaces such as Ethernet (10/100 Mbits/s), USB and CAN.
Featured with power-over-Ethernet, the board is independent from an external power supply and could be used in applications where cables cause complications.
Since April 2008, ChameleonARM is available with USB Host/on-the-go function, the new order number is Chameleon2388. |
Hardware Together with Fraunhofer IMS, EBV developed the board
as a flexible system based on the LPC23xx microcontroller family. A power supply is possible via USB, power-over-Ethernet and DC jack.
The board is equipped with all the necessary transceivers
and connectors to support the MCU communication interfaces including USB, CAN and Ethernet.
The size of the board is 75 x 130 mm and is built as a modular system, where additional functionality can be supported via EBV standard connectors (120-pin Hirose).
There are several add-on boards availble. For more information see below. For further information please contact

ChameleonARM Board
Background Information on the LPC23XX Family
One of the key advantages of the high speed LPC23xx with 72 MHz performance is the provision of two independent advanced high-performance buses (AHB) with separate SRAM areas that are dedicated to the USB and Ethernet controllers.
Both are separately connected to the local bus and have an AHB1 to AHB2 bridge to allow direct communication without any CPU workload.
This dual AHB system provides simultaneous Ethernet
DMA, USB DMA, and program execution from on-chip flash memory with no contention between those functions.
In addition to Ethernet (10/100), CAN and USB are provided. With the new generation, Chameleon2388, USB host and on-the-go (OTG) function is available.
Standard interfaces like UART, SPI, I²C, I2S and JTAG are on-chip as well as an SD/MMC card controller. There are also eight analog input pins, one digital-to-analogue converter (DAC), several GPIOs and an ISP interface for in-system programming. |
Software
The ChameleonARM board is provided with installed Webserver-Reference-Applications showing the following features: - network connection via Ethernet and USB (RNDIS)
- Plug & Play network configuration (ZeroConf)
- automatic IP assignment (Auto-IP)
- device can be registered as service on the network
(DNS-SD) - simple access to the device using its name
(MDNS, NETBIOS) - real-time visualisation of measurement
values / parameters (Java based) - video streaming (using the web server)
- user access protection with user / group permissions
(HTTP authentication) - resource saving time-tested TCP / IP protocol stack
- all necessary Ethernet protocols included (ARP, DHCP,ICMP, DNS, NTP)
- high transfer rates (Ethernet, 100Mbps)
- routing between several networks (NAT, port forwarding, DNS-routing)
The remote NDIS (RNDIS) network access via USB is based on Thesycon‘s USB device software stack and implements an Ethernet connection with the standard RNDIS drivers shipped with Windows. The Ethernet interface driver, the complete TCP/IP protocol stack and the advanced demo functionality that combines both Ethernet and USB networking, comes from the sevenstax embedded Internet protocol library. Both software components are optimised for the LPC23xx hardware platform and perfectly interact on any embedded system with or without an operating system environment.
