Propeller and ssc-32 communication?

I’m new to the forum and new to the Propeller chip but not new to the SSC32 servo controller. I would like to communicate to the servo controller with Spin.
Is anyone dabbling with the two together.

I’ve tried the Full Dulex serial object, but getting no response. I’ved used the servo32 object just fine. (servo to propeller chip)

I’ve gotten the BlueSmirf to work great with the SSC32 at the moment!

Any light shed on this would be very appreciated!

Thanks,

Tony

Can you talk to a PC serial port with the full duplex command? If so you should be ok(SSC32 talks to PCs too). If not you may need to invert the signal.

I finally figured it out. Woohoo!
Learning a new langauge takes alot of tinkering and guessing… and tinking and guessing…
Using the Full Delux serial object, I wrote;

SSC.str(string("#0 P1500 S1000",13))

or if I wanted to use the time command that the SSC-32 has, I’d write;

SSC.str(string("#0 P2000 #1 P1500 #2 P1000 T2000",13))

I’m even communicating in the 115200 baudrate!
So, I’m making alittle headway.

Thanks for responding Acidtech!
Ya, hopefully I can figure out how to get the SSC-32 to talk back.
That would be cool.

My next problem is, taking in an input, say an accelerometer, and having the servo move accordingly. I’m having a hard time figuring out how to change the ASCII number in the command line.

In Mbasic, you just through in the “dec variable” in the middle of the line and the variable can change to whatever, which is convenient. I can’t do that in Spin.

So…more tinkering!

Hello,

I’am interesed also in interfacing the SSC-32 to the Propeller chip. How did you do it ? happen to have any schema’s ?

Thanks in advance.
