DATA ACQUISITION AND DIGITAL SIGNAL PROCESSING USING THE HANDYBOARD
Digital filtering(under construction)
Fourier analysis
Correlation(under construction)
In the links above, the HandyBoard is used as an ADC to send data to the PC at 9600 Bps through the serial port. Data is computed on the PC with programms written in C. If data processing doesn't need to be real time, the HandyBoard may also be used as an autonomous data recorder by simply storing the data in the empty space of the SRAM but this aspect isn't focused here.
To try out the links, you need a HandyBoard, Interactive C compiler and a Borland or Microsoft C compiler. For more information about the HandyBoard, you may follow this link
You may use as well any other data acquisition card with 8 bits (or more) ADC, but the advantages of the HandyBoard are numerous:
- the 68HC11 microcontroller used on the card understands C language thanks to an interpreter
- there's enough memory on the card to configure it as an autonomous data recorder (for slow variyng signals)
- and finally, if you are borred with data acquisition you can start building ROBOTS. This is the goal for wich the handyboard has been created. (it comes with 4 DC motor outputs, numerous digital an analog inputs for sensors and microswitch...)
