  1. Android simple TCP client extension for MIT Application Inventor 2

    Attached, there is a simple TCP client extension Name:  TCP.png
Views: 313
Size:  324 Bytes that implements a very simple socket; note that its operation is performed 'one-shot', which means that only one command is sent ( and its respective response, read ) at a time, and then the socket connection is closed. So, be aware that it is not a generic "shell" implementation, therefore not keeping always connected. Another point to remark is that connection is not allways checked, which means that data ...

  2. Android client ThingSpeak extension for MIT Application Inventor 2

    The following attached file contains a ThingSpeak client extension Name:  IconTS.png
Views: 416
Size:  785 Bytes that allows one to easily make use of the Read and Write features of the ThingSpeak cloud service provided by MathWorks in such a manner that programmer is able to transparently make use of the service without having to deal with much details of the implementation in the code side. With the App - also attached - you can easily check the extension working on a friendly interface:

  3. Android client SSH extension for MIT Application Inventor 2

    The following attached file contains an SSH Client extension Name:  ssh_hkj_icon.png
Views: 587
Size:  271 Bytes which I made for my own use, but it may also be useful for users of the MIT Application Inventor 2 (AI2) community, or even to the AppyBuilder community (code intrinsically compatible for the last one, but not tested). This is just the current stage of development, but if you want to get updated revisions, you can get the last released source code at Github.

  4. Working through Annex I.1 of the 802.11 PHY standard in MATLAB


    Note: In earlier versions of the 802.11 standard, the (BCC) OFDM example was given in Annex G. However, an error existed (e.g. in IEEE Std 802.11-2007) in that the FCS was incorrect (see link or search online for "IEEE 802.11-09/0042r0").

    The WiFi (802.11) standards documents are free to download from the IEEE webpages (see, for example, here). (Sadly, you are required to register first, which I would describe as irritating and pointless).

  5. Routine for handling 7-seg display on CCS

    The following function may be useful for those who are starting in the microcontroller's world and wish to implement applications using 7-segment display with the CCS compiler in PIC platform. I've used long time ago:

    Code:
    void Display7seg ( char value )
       {
       char pin=0 ;
       while ( pin< 8 ) 
           {
           if ( SEGMENTCHARS[value ] & ( FIRST_SEGMENT >> pin) ) 
             output_high ( DISPLAY_PINS[pin] ) ;
           else
