    Hi John, I'm not familiar with the "Serial" object you are using. Could you simply backup your code into an archive and post that so I can see. Looking at you serial transmit loop it looks like you are sending a command 10 times a second. Is this update rate correct for your requirements?

    Okey, so, the "Serial" object is actually FullDuplexSerial. In that code it says it was update every 100ms, In the other code it was updating every 1-10ms

    Just remember, it could have been just how I was interpreting it, it might not have been a speed issue. I can't test this however because both my motor drivers are "broken".

    Wow. Just wow. I just had the HB's arrive in the post, and wow. They are nice little drivers, some of the best I've ever seen...

    One question though, I know that this is the same across the board, but why do drivers/parts not come with their own bolts? (Not to worry though, I've got some computer case bolts to fit)

    Thanks,

    John

    A bit excited there John? Better bolt off then....
    Yeah, why don't they throw in a few lousy screws and mounting posts. There you go Parallax, that's truly the "hardware" side of the business, the nuts n bolts :)

    Am I excited? Yes sir! These motor drivers have the best chance of working out of all my drivers. I prefer things that don't require any fancy wiring - the HB's have the stock standard 3-wire headers that I can plug straight into anything, and they only require a servo-style pulse to drive them, most MCU's can generate those pulses ;) Also I'm quite a bit excited because I've layed off my fancy TAOS color sensors for something a bit less resource consuming, the ColorPAL's. I found the TAOS's were quite a bit too sensitive, and the red channel always spiked a bit... But anyway, the ColorPAL's should do the job well. Although, they can't update nearly as fast as the other ones could - but anyway, I guess there always is a tradeoff.
    Better bolt off then...
    :P

    Well, I'll let you know how it comes along, and I agree with you. Parallax! Throw in a few screws with your parts!
