The idea for EBV’s ChameleonARM platform was created when NXP introduced the 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 showcasing both the processor power within the ARM7 environment as well as the communication interfaces such as Ethernet (10/100 Mbps), USB and CAN.
Featured with power-over-Ethernet, the board is independent from an external power supply and can be used in applications where cables cause complications.
The board measures 75 x 130 mm and is built as a modular system, where additional functionality can be supported via standard connectors. Add-on boards such as analog input boards, graphic accelerator, Lon networking and audio/codec, can be plugged in via these connectors.
The ChameleonARM board is provided with installed demo software demonstrating features such as network connection via Ethernet and USB, automatic network configuration, automatic IP assignment, realtime visualisation of measurement values and parameters, and video streaming.
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 demo functionality that combines both Ethernet and USB networking, comes from the Sevenstax embedded Internet protocol library.
