  1. 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).

  2. 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:

    void Display7seg ( char value )
       char pin=0 ;
       while ( pin< 8 ) 
           if ( SEGMENTCHARS[value ] & ( FIRST_SEGMENT >> pin) ) 
             output_high ( DISPLAY_PINS[pin] ) ;
  3. Programmable Cyclic On-Off Timer with Relay Output

    This project is to build cyclic on-off programmable timer. In this project user can set ON timer and Off time using keys and 7 segment display. Relay is provided as output, where relay will be remained ON for ON time and it will goes OFF after ON time overs. And Relay will remain Off till Off time overs.

    Components required for the project:
    1 x PIC16F876A
    4 x Keys
    4 x 7 Segment

    Here is hex file path: ...
  4. What Programming Language Skills Do Employers Want?

    "What programming language skills do employers want? Online job-search firm Indeed took a look at three months (18 May to 18 August) of 2018 job listings in its tech software category to find out. The company ranked programming languages according to the percentage of job postings within the category that included mention of the language."
  5. David Patterson Says It’s Time for New Computer Architectures and Software Languages

    Moore’s Law is over, ushering in a golden age for computer architecture, says RISC pioneer

    David Patterson—University of California professor, Google engineer, and RISC pioneer—says there’s no better time than now to be a computer architect.

    Some highlights

    "As an example on the software side, Patterson indicated that rewriting Python into C gets you a 50x speedup in performance. Add in various optimization techniques and the speedup increases dramatically. ...
