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

    Thanks for such great blog. Was wondering how can I reach you? I need to ask you from a few things if you don’t mind.

    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.

    This is such a great blog. Are you no longer updating it?
    I’m learning so much in the world of SDR. Especially the articles you wrote about 1. ADC readout and USB2.0 data transfer with an FPGA, 2. A GNU Radio Source Block for the FT232H USB 2.0 controller and finally most importantly, 3. https://digibird1.wordpress.com/build-your-own-software-defined-radio-sdr/ Woud love to know if you know more articles like these. Would you be nice enough to let me contact you too?
