Data Logging & Configuration with
Web-Interface

The EVB90363WEB is a development tool for Melexis' 3D-Hall Triaxis Sensor MLX90363. The evaluation board is based on two components:
   • MLX90363 Triaxis 3D-Hall Sensor IC on a small adapter board
   • Internet-Gateway-Module WIZ107IO with web server and a graphic frontend
     for visualisation and configuration.

    
Block-Diagram EVB90363WEB                 Web-Interface

The WIZ107IO Internet module communicates with the MLX90363 3D Hall sensor by SPI at 3.3 Volt over an integrated voltage regulator at an external power supply of 5V. A real-time 3D visualisation and a high speed data logging of the x-, y-, z axes of the magnetic field are provided by the Internet module and the web frontend. No software is needed and any browser will do. You can easily change the network configuration over the graphic interface e.g. DHCP to static IP. The module can be addressed by SMB-name or IP number.
The content of the internal EEPROM of the MLX90363 can be read and configured over the GUI, the content of the RAM e.g. for diagnosis purposes, as well.

Features:
- real-time 3D graphic output
- real-time data-logging and save to file
- read/write of MLX90363-EEPROM for configuration
- read MLX90363-RAM
- DHCP or static IP, default: 192.168.0.3
- SMB (NetBIOS) name resolution, default: MLX90363
- open source code available

MLX90363 Absolut 3D Position Sensor IC
The MLX90363 HALL position sensor is a monolithic sensor IC featuring the Triaxis™ Hall technology. Conventional planar Hall technology is only sensitive to the flux density applied orthogonally to the IC surface. The Triaxis™ Hall sensor is sensitive to the 3 components of the flux density (Bx, By & Bz) applied to the IC using Integrated Magneto Concentrator (IMC). The MLX90363 senses the absolute position of a magnet moving above it. It enables the design of contactless joystick (3D) and linear (1D) position sensors.
Intrinsic Linearity Compensation through Front-End Calibration is applied in manufacturing process. The Hall position sensor is qualified for automotive and industrial applications.

Key Features MLX90363
• TriaxisTM Hall technology - absolute 3D position
• Simple & robust magnetic design
• 14 bit digital X, Y, Z or Alpha + Beta out
• Full duplex SPI protocol for EEPROM read & write
• Trigger pulse for synchronized parallel readout and speed calculation possible
• RAM readout for diagnostic and SIL ready
• Power supply range: 3.3V or 5V
• Operating temperature range: –40° C to +150°C
• Single & Dual Die - SO8 & TSSOP16 Package

WIZ107IO Gateway Modul
WIZnet's WIZ107IO module combines the W7100A hardwired TCP/IP Internet chip with a low-drop voltage regulator. An RJ45 jack with an integrated transformer; status LEDs and two bridge rectifiers supports the operation as a "Powered device", like Power over Ethernet (PoE).

Key Features WIZ107IO
• Hardwired TCP/IP SoC W7100A (64k Flash + 64k RAM)
• 4in1: 8051 MCU, TCP/IP, MAC, PHY (10/100MBit/s)
• UART I/F: TTL and RS232
• 8 universal GPIO pins (here software SPI)
• Integrated 3.3V low dropout voltage regulator
