Servo Center 3.1 and BS2

NWUpgrades

I have a Servo Center 3.1 Serial Interface 32 Servo Controller board. I am trying to figure out if there is any way that I can implement this in to a BS2 chip on a BoeBot Board. I am pretty sure there is a way to code it in VB 10 but I was hoping that there may be someone ot there that is smart enough to figure out a way to connect it directly to the BoeBot board and program it using the PBasic. Here is a link to the schematic for the SC 3.1 http://tech.yostengineering.com/servoFolder/servoFolder/servocenterUSB/ServoCenter31Schematic.pdf

If the BS2 can send the controller serial commands it should work. I don't remember what baud rates the BS2 can support. The slowest baud setting of your servo controller is 9600 bps; I don't know if the BS2 can communicate this fast.

If you can communicate with the controller, you'd just send it commands. The protocol is available here.

jp1 pins 3 and 5 look like where you would connect.

So where would pins 3 and 5 go on the BS2 and how would I code it to be able to operate the servos?

Pin 3 and 5 are the TX and RX pins from the stamp and as to programming the Servo Center 3.1 should have the instructions on what it expects from the communications device.

OK, Great. I think I got it. I learned a while back ago on how to connect VB through PBasic and back again so I should be able to get it to run that way. Thanks for the help.

One other question that just came to mind. Would I need to connect a ground from the ServoCenter board to the BoeBot board? I know it may seem odd, but I have found in the past with Stepper Drivers that I have to do this.

Yes, a ground is almost always required for the return path between devices. You may also consider current limiting resistors on the pins you connect between devices as insurance from damaging the stamp.
