SD is also pullup so it mean that not connected sd is sd=1.

    Reagards

    Tried to copy UHU's part but failed Changed the layout according to your point and ELM-CHAN's circuit.

    the ir fet drivers shut down pins could also be attached to the error led which would ensure fet turn off.

    Yes for shure but SD should be =1 together with in=1 to have LO and HO both 1. It can be used like you advice. But did you tried to meke like this??

    Did you changed already?? I made one prototype already but I did not tested because have some problems with 2313 programmation. Thanks mcm_xyz (my respect and regards to him) I think I will manage programmation problem. Due to connection of SD check datasheet and signal diagram downsteitr.

    evaluation question (a little out of topic).

    Hello.

    I think many of you have encountered the problem where CNC software in windows especially lacks the ability to generate very stable pulses. This causes motors to vibrate and even jump over steps. So I intend to create a AVR controller (based on attiny2313 i hope) that will receive commands from the computer in a form:

    GO 1000 2000 3000

    where the parameters are the the number of steps the controller has to generate on 3 axes. The controller will be configured to have Vini, Vmax and Acc for each axe and will generate on 6 pins step,dir pulses.

    The drawback for this is that windows software will have to be modified to output commands on a serial port. I also have a Delphi7 project that commands a 3 axes machine that I can modify easily and also make open source.

    So the question is: will this be a good thing? Is someone interested for that? Does anyone know any similar projects? Is there a standard serial protocol for that?

    Many many thanks.

    Mike

    Hi Mike!
    It seams to me long time ago I was checking Mach2Mill. One of version I do not remember which had additionl as an optnion buttun in motor tuning. It was servo setup to drive servodiver. I remember that it was up to 5 params with needed to be installed. Check all versions of Mach for buttun servo setup (in motor tuning). I thin you are tolking about this. By the way Mash is the coolest soft I tried. Mach make correct PWM to drive steping motor. Motors going very smooth if it will be compared with Kcam.

    Regards
    Alex.

    Hello!

    So did you made finaly controller?? Does it work???
    I would like to ask you on your previouse schematic you placed here there is R2 and R3 can you tell me nominals I mean how big is resistanse? Also do you have PWM on leg 15 and 16????

    Regards
    Alex.

    Hi Alex,

    Sorry for late answer. Your point about R2 and R3 values made me check the schematics again, and I saw the point.

    When you look at the schematics from http://elm-chan.org/works/smc/report_e.html (namely circuit diagram for smc3/a and High Power Drive) those resistors are not necessary... My mistake.

    The High Power Drive schematics of elm-chan.org is almost the same with the UHU power drive part posted by smarbaga. 1st pins of IR2184s is directly connected to OC1A and OC1B pins of AtTiny2313. I will update the schematic and upload it again.

    I also added max232 for communication.

    But I haven't made the pcb. I could not find IR2184 chips in electronics stores in my city, will check from another city.

    Hope this helps.

    Hi!
    I think resistors needed for pullup or to decrease a nose. so shematic looks like mine. This evening I had started with my controller but I have an errors. I need to change parameters. Also I am not sure in my encoder.
    Regards to Mike. Thanks for help.

    Regards to all.
    Alex.
