    Hi everybody.
    I need to know something fundamental to build the electronics that best suit my needs. I have to use SimTools and Arduino Uno R3 to move my simulator.
    I need to know: how many bits does the PWM frequency of SMC3 v1.0, 8bit or 10bit have?

    I think there are 255 steps on a standard uno pwm

    Its not a lot but combined with a fast pid loop it's good enough

    What is more important is the resolution of your feedback position

    Ive noticed that your using SMC3 ver. 1.0? is it more reliable then 1.1? im having a hard issue with data loss.

    Version 1.1?
    I have checked and the latest version is SMC3 v1.0

    You maybe get confused with the "SMC3 utility" tools
