The demo board

The demo acquires angle and distance from a compass and a ultrasound receiver, sending them to a remote system using an XBee module connected through UART.

On the PC side, then, a GTK graphical application (not available for download) displays the data in a polar plot.

Board schematics, PCB and software available as a template under ERIKA Enterprise.

Software

The software is an EE application which acquires information from a compass and a ultrasound receiver, sending them to a remote system using an XBee module.

The application is distributed with ERIKA Enterprise since version 1.4.0, and shows how simple is the implemenattion of a Zigbee-serial gateway which interfaces SPI/I2C peripherals with a dsPIC.

Hardware

This is the list of hardware components needed to reproduce the demo: 

• FLEX board (light or full)
  
• home made PCB (Eagle design and schematics available in the template);
• a few resistences and connectors
  
• a ZigBee modem: XBee from MaxSream;
• a compass: CMPS03;
• an ultrasound sensor: SRF10;
• on the PC side, an XBee module with the USB interface
