    Slovenac,
    ovaj servo-driver nije vredan truda. Utrošio sam novca i vremena oko njega i na kraju odustao. Kad vidiš oko jednog otvorenog projekta mnogo varijanti i polemike skloni se od toga i poštedi sebe. Ovde vidiš da se prvobitni autor ne pojavljuje a nakačilo se svega i svačega pa čak neki pakistanac ili iranac to navodno prodaje kao njegov projekat.
    Pozdrav!

    Hvala za opozorilo!
    Sem opazil, da originalni avtor ne odpisuje več!
    Lep pozdrav!

    Da, autor se dugo ne pojavljuje a nakalemilo se entuzijasta koji sve više razvodnjavaju prvobitni projekt.
    Osnovni problem je što IR2184 ne daje dobre rezultate kad PWM dostigne 100% koje mu ATMega šalje. Meni je dugo trebalo da shvatim da od ovog treba odustati.
    Na donjem linku možeš videti realizaciju kontrolera koji nije na platformi ATMega i snimak sam uradio danas. Treba još malo uštimati PID parametre i mogu reći da je ovaj kontroler pun pogodak.

    Kontroler NIJE zasnovan na Atmelu. (The controller is not with ATMega)

    So whats the final word on this, does the code work or not? I am wanting to use something like this on a pcb router. I already have some extra electrocraft servo's and all the hardware to start building, I just need to build the servo drivers. I have several extra mega88's and some H-bridges so the hardware isnt an issue for me, but whats the state of the mega88 code as well as the tuning software?

    I have made such a dc servo controller board josepz, using atmega88, the results failed .. I check the contents of the hex file atmega88_3_3, atmega compint modif and all atmega hex file using the Proteus software "watch dog trigger" ... probably the source of the misleading ... please comment ... greetings from IndonesiaAttachment 224170

    Re: Modernization of the Elm Dc Servo Controller (Russian UHU by Hudognik)

    Hi everyone!
    i've made three servodrivers of this type.
    So far they work ok on the test bench:
    https://www.youtube.com/watch?v=3kRuQKLGUfI

    But there is one problem when connecting them to PC through LPT cable. Look at the step-dir circuit:
    Attachment 260684

    There are two optocouplers that recieve two signals from LPT cable: STEP and DIR. These signals are active LOW - they are sink type signals - LPT pin goes ground to make internal LED in optocoupler transmit signal to the output. To make it all work you need common +5 volts supply connected to pin no 9 on XP1_1 connector. To be trully electrically isolated from PC this +5V must come from PC but there is no +5V on LPT port! So where do you guys are taking this +5V from??

    I'm also considering differential transmission system on encoder->servo drive line to avoid noises. This is very often an issue and leads to lost steps... Let me know if enyone will be intersted in PCBs...

    This thread became a little confusing for me as far as which versions were working and what was not. Would you mind sharing your code and schematic? I have been very seriously considering building some of these.
    Thanks.

    I'll try solution with +5V fron USB - have you tried it? I assume GNDs must be connected together (USB&LPT) to avoid noises, spikes...

    punisher454: i'll put the code i used to program my microcontroller as well as pcb&sch. I just have to back home and sit in front of my PC.

    I haven't tried it in this application but it is how I power my BOBs. The one I just bought even has a usb port solely for getting the 5vdc

    Re: Modernization of the Elm Dc Servo Controller (Russian UHU by Hudognik)

    I went back and had a look at my previous attempt to translate the program comments from Russian to English. Yes it was a total mess, and the code was totally screwed up. So I spent a few hours comparing each line one at a time to the original Russian commented file and fixing it.
    It is now very readable in English and builds just fine in Atmel Studio 6.2. A code comparison in a hex editor shows the hex file's are identical.

    So here it is.

    I plan to build a board based on this code soon. I'll post here with my results.

    Marvin

    PS. there are still a few words that didnt translate well, one in particular translated to English as "not Spanish"

    I have some (8) of these very nice design boards as left overs.
    Professional made thruhole plated boards.
    I would say 5 euro each, this included the little booster board.
    have also the IRF540N + 620100 each 1,25 euro new
    Tiny quarts 8 - 16 - or 20Mhz 0.75 new
    This is a nonprofit sell just to cover my next project.
    Send from Holland to any place as long as you cover the shipping costs.

    hi!
    do you have any pcb ready for me?
    i try to make 4 of this circuit but I find some problem whit the gnd
    og motor end gnd of logic, my pcb work fin whit little power
    but for one axis i need almst of 300W your is able to menage?
    Let me know how much do you want foe one pcb, I need 4 of them!

    nobody have find a trouble when programming a new atmega88?
    I find trouble after a rigth programming, when star a connection whit a pc by serial cable
    I receive the welcome signature li " ervo controller...."
    are missing te "S" of servo!!! and if I try to conect more time like 2 or 3 times
    the servo go in error, the main strange is the sistem is on work condition!!

    PM me the lines with "unknown" Russian words, I will try to help you. I see some words with "mistyping" in Russian by Latin letters.
    For example:
    otkolnenie => otklonenie => Deviation, in some cases can be translated as Error
    pred.versiyah => previous version
    bufura => buffer

    Still havent gotten a chance to send those particular comment lines. All my computer archives are unavailable to me right now while I upgrade my network storage system.
    soon..
