4 motors on 1 PIO block -

running commands in sequence
running all commands concurrently

[View:https://youtu.be/Hhug2iatza0:640:360]

Commands:

        { {200 * microstep_x, true}, 0},
        { {200 * microstep_x, true}, 1},
        { {300 * microstep_x, false}, 2},
        { {200 * microstep_x, false}, 3},
        { {10 * microstep_x, true}, 2},
        { {200 * microstep_x, false}, 1},
        { {20 * microstep_x, true}, 0}
