Hi Dan,



installing some software on the DSO Quad is much more simple than you might think (and is explained in this thread (first message - which I quote after the link - but just read the general procedures after the quote):

an even better guide is this one here:

You can do all that upgrading or softwarechanging, after you connect the DSO Quad to your PC via USB and while turning on the DSO Quad, pressing the first button "►||" on the left of your DSO Quad. (It will then show up as a drive on your PC)

--> The firmware/software for the DSO Quad consists of 4 things:

[list]

  • FPGA
    • [/list]
    [list]
  • APP
    • [/list]
    [list]
  • SYS
    • [/list]
    and if you wish
    [list]
  • logo
    • [/list]

    the FPGA and the logo consists of 2 Files each: you first have to “send to” or “copy/paste” into the DSO Quad drive a / the “xxx.ADR” file followed by the matching “xxx.bin” file

    –> “xxxFPGAxxx.ADR” and the “xxxFPGAxxx.bin” for the FPGA and “xxxlogoxxx.ADR” followed by “xxxlogoxxx.bin” for the Logo



    APP and SYS are “xxx.hex” files and for those, you only “send to” or copy/paste a/the “xxx.hex” files to the DSO Quad drive - the DSO Quad then automatically reboots and reconects with your PC, showing a “xxx.rdy” file on the DSO Quad drive.



    The combination of FPGA, SYS or the APP is what seems to be an issue, as all have been updated several times and based on on or the other code, SYS and APPs have been improverd or developed - but there is not much that can happen to the DSO quad

    Thanks for the good work.



    On my DSO I noticed a discrepancy in generator frequency and displayed frequency.



    Edit: Latest Marcosin SYS file shall be used (thanks Jerson!, see next post)

    #115

    I remember having this same problem. Please check that you have the latest Marcosin SYS file. See the sticky post on this thread which explains what you need.

    Hi elfe111,



    Thank you very much fir the links and information!

    Thanks for your excellent work on this build (v1.21). One minor bug that I have not been able to sort out.



    When triggering from Chan A, on manual, down transition, 2ms per div, it works perfectly on full buffer mode, but when I switch to short buffer mode, it appears to trigger OK about one sweep in 3 or 4, and then free-run for the next 2 or 3 sweeps.



    If you have any ideas where I might look in the code, I’m happy to try to sort it out, but I’m not sure where to look to start with.



    Thanks again

    Jerson, just to be sure, can you post a screenshot of your start screen? Mine looks like this http://seeedstudio.com/forum/download/file.php?id=1026



    My DSO still suffer of the strange scerenshots…

    #119

    Sure. Here it is.

    #120

    thanks! looks like mine (except i use app v1.21)… hmmm why then is my screenshot function strange? did you use the fgpa version from seeed?



    cheers

    #121

    I have the latest FPGA - don’t remember the URL. However, to make it easy for you, this is what is loaded on my quad.

    #122

    I see that most use SYS 1.50-1.6. My quad came with SYS 1.51.

    Are there any known advantages for either version?

    #123

    The DSO GCC APP is made to work with Marco’s SYS 1.50-1.6.

    Other versions will mostly work but have issues, like wrong generator outputs.

    #124

    Can you tell me please where can I find it?



    Thanks,

    Dan

    Hi Dan13,



    you find Marcos Software here:

    <LINK_TEXT text=“http://sites.google.com/site/marcosinat … ronica/dso”>http://sites.google.com/site/marcosinatti/elettronica/dso</LINK_TEXT>



    V1.6, V1.7 and V1.8 are at the bottom of the page (but the link to V1.6 does not seem to work anymore - but that is his site anyway)



    so just klick here:

    just marco’s sys…

    Thanks guys!

    Just got my Quad the other day.

    I’ve been testing it and compiling the source in prep for a project I have to finish soon.



    Found the following what appears to be a bug with the code:

    Triggering with Timebase at 0.5uS and rising edge never causes a trigger event.

    Changing to negative edge triggered however works ok.



    I have downloaded and installed the following:

    1.50 SmTech 1.6

    The latest source and also double checked that the Hex file does the same thing: (2.52+SmTech1.8+PMOS69 fixes)

    Latest FPGA firmware



    Feeling pretty ripped off however as the site I bought it off is still advertising:

    4MHz is not 72MHz by any stretch of the imagination.



    Glad others are however working on making it a usable product assuming the bandwidth limitation is not a problem.

    Hello :slight_smile:



    I want to update my DSO203 but really i am not sure what to do.



    I have read the posts of this thread.



    What i have understood (please explain if i am wrong) :

    In order to have an APP compatible with a SYS i have to install :

    Marco’s SYS 1.50-1.6

    DSO203 GCC v1.21 APP



    Concerning how to install the DSO203 GC 1.21 APP there are instructions so i will follow them.



    But what am i supposed to do with the files :

    APP25116.hex

    SYS25116.hex

    CFG_FPGA.ADR

    V222FPGA.BIN



    ?



    Thanks,

    Hello RemiD



    I may not be the best person to answer your question, but, I’ll tell what I know



    The files you mention are needed to upgrade the DSO203



    SYS is the backbone of the DSO203.

    APP communicates with SYS and gives the DSO its personality. So, different APPs you can find have different UIs.

    CFG_FPGA.ADR and xxxFPGA.Bin are to be loaded in sequence (without powering off the dso) to the DSO203 as explained elsewhere on this site.



    If you still have doubts remaining, ask here.



    Easter greetings

    Hi Jerson :slight_smile:

    Can you please tell me where i can find the step by step procedure on how to load the SYS files to the DSO203 ?



    Thanks,
