This is my private blog, mainly for documentation of some interesting projects I do in my free time.
As one can see I’m highly interested in programming and electronics.

    Hello digibird1,

    Actually, you have a great blog with some great articles, specially those SDR related articles. Please keep up the great work.

    btw, how can I reach you? I need to ask you a few questions concerning the SDR building article.

    Much Regards

    Thank you for the great info. You’re developing a sizeable following, I was hoping that you could let me know where to reach you too?

    Hi. Very nice practical project. I need some helps about ADC and FPGA interface.
    Do you mind if I ask you some questions. Can we be in touch by email.
    Thank you

    Hi. Your work on the Deo Nano Soc is better than any published work that I have seen to date. Thank you for your great work. There are still a few issues I am working on as I am using a variation of your work on one of my projects. If you have the time, I would like to ask you a couple of questions about that project. Please let me know how I can contact you.

    Dear digibird1 ,

    From : gregoire bellamy – mail : ngbellamy@orange.fr – France .

    Concern : Your program Arduino as a SoundCard (AudioPWMPlayer.ino) .

    First please excuse my poor english , I have some difficulties to write in english .
    I hope that I am not disturbing you .

    I am trying to understand deeply FIFO and I find your FIFO lesson theory interesting .

    I have compiled AudioPWMPlayer.ino but I did not understand deeply when and how you
    write bytes into buffer , and when and how you read bytes from your buffer .
    The program is important , difficult , because the need of a another program sending data
    to Arduino .

    Could you teach me the FIFO theory with a simple example that I can experiment
    with my breadboard ?

    I have to activate 16 relays ; demultiplexing is ok . My commands are simples ,
    eg : Relay1 ON ; delay 1000 mS; … Relay15 ON; delay(100); etc …

    I want to put these commands on a 2 GB SD Card (SdFat library routines ok) .
    Ascii file for combinations written on Sd card by PC ok .

    I understand your routines : (fifo_init(&myFIFO, Buffer, 1024) , fifo_write (&myFIFO,
    &inByte, 1) … fifo_read(&myFIFO, a) .

    But I don’t known how to tell Arduino to read these commands from Card , put them into a buffer
    and how to read buffer sequentially to activate my relays until EOF !
    My process is slow .

    Could I expect a gentle response ?
    Please agree my best regards . Gregoire .

  7. Great blog!
    I hereby encourage you to share more.
    SDR stuff is legit, would like more info on FPGA section of your DIY SDR article.
