Sample applications

To give you an easier start-up with the i-easy this side lists some testing and sample application set-ups and source code. All examples are provided as they are and come with no warranty.

We kindly thank our Hong Kong distributor Thomtronics Technology Company for providing these application examples.

Application examples

 

i-easy pro:

 
  Description Resources
(Photos, Source Code
CodeVision AVR C)		 Remark
1. Read I/O state
  • connect to alarm system, home security sensor,etc.
  • read switch status
  • any electrical failure will generate an SMS message to the portable phone, or send an email to the receipent's list.
    		•  Photo, Data change of I/O input state will refresh I/O status in the web
    2. Read ADC
  • read analog signal (temperature, pressure, light, resistance, etc)
    		•  Photo, Data refresh ADC status to the web at designated time interval
    3. Receive data from equipment with RS232 (such as realtime pH meter, dissolved oxygen meter, etc.) and send data to the web. Photo, Data  
    4. communicate with Dallas DS18(B)20 temperature sensor Photo,
    Sample Data:
    DS1820, DS18B20    		 send temperature alarm to the web
    5. Fetch image from CCD and upload image to the web Photo, Data Fetch image to the web
    6. Read Counter Value
  • update number of visitors entered or exit, etc.
  • update production line counter value to the web.
  • update number of items or drinks inside an automatic vending machine to the web.
    		•  Photo, Data update counter value to the web at designated time interval
    7. Connect to the web, fetch a *.txt file from the web-site and display the *.txt in the lcd display. Photo, Data

      Description Resources
    (Photos, Source Code
    CodeVision AVR C)    		 Remark
    1. Receive RS232 data, and send the real-time data to the server. Sample Data  
    2. Send real-time temperature data to the web server at time-interval. Sample Data  
    3. Send Alarm SMS message to Portable Phone (with SMS function)    
    4. Send security status to the web.    

     

    Remarks:
    As most people ask the same question - "What can the i-easy pro do for me?" - Thomtronics just mentioned a list of projects in the above list. The above projects are proposed by Thomtronics Technology Company and may not be implemented or released to the public.
    Please fully use the appropriate discussion board in Thomtronics's web-site or www.embedded-inet.com for discussion and for more information.

     

     

    letATwork Starter Board

    [The letATwork is a plain AVR controller microboard providing easy access to the AVR controller in custom hardware setups. For further information please visit bergmann-electronics.com.]

    Most of the following projects can be implemented in the i-easy pro as well.
