When I purchased my EZ-B kit last year, I also bought the BV4113 H-Bridge that EZ-Robot was selling at the time.
I now want to use it to control the wrist and grip motors in a robotic hand that I got in an equipment trade from Josh. I found a datasheet and sample code here http://doc.byvac.com/index.php5?title=Product_BV4113 that shows I should be able to control it using send serial script commands, but I have a couple of questions.
1) When DJ was selling the device, he made a firmware change for port D0 specifically to support this board. If I want to use it with Send Serial commands, do I also need to use port D0?
2) Has anyone else done this, and if so, can I borrow your scripts?
I guess a 3rd question. Is this even a good idea, or since they are simple motors and I only need them to run for a few seconds at a time to position the hand, should I just use Rich's Darlington Transistor circuit and save the BV4113 for another project where I need a movement panel?
