Sensing machine gains ICE support
Xemics and Phyton have released the first in-circuit emulator (ICE) for the XE8000 microcontroller series and sensing machines.
Microcontroller takes on smart radio applications
New from Xemics the XE88LC06 is a microcontroller for smart radio applications.
This new high-resolution smart altimeter module MDS-02-0010 with interface for 2D electronic compass will be demonstrated during Sensor in Nuremberg, 13th-15th May 2003.
The SMD module features a high-performance piezoresistive pressure sensor, and uses a low-power 8bit MCU with internal 16+10bit ZoomingADC from Xemics' range of sensing and radio machines.
With its integrated firmware and calibrated pressure sensor, this device supplies a designer with the processed temperature, atmospheric pressure, altitude, electronic compass heading and battery level information.
This high integration level facilitates easy access to sensor technology without the need for any background experience in it.
The low power, low voltage smart altimeter module is easily interfaced.
Resolutions of 0.5m altitude and 0.05mbar barometric pressure are available.
The thermometer has a resolution of 0.1C.
All information like atmospheric pressure, altitude, temperature, compass heading can be accessed by the optimised host MCU through its synchronous serial interface.
A proprietary compensation algorithm for magnetic perturbances is implemented in the compass firmware.
The compass has a resolution of 1 degree.
Higher resolution is available on request.
This module is available now and can be used with all existing magnetoresistive sensors, for example those from Honeywell, Philips and Sensitec.
