Sync Write

Your problem appears to be the '4' in position 7 - that is the # of bytes you are writing for each servo, and should be 2 in this case.

This is what I get:

ff ff fe 10 83 20 02 01 ff 03 02 ff 03 03 ff 03 04 ff 03 3a

Sync Write

2007-06-03T06:52:56+01:00

Hey Guys,
I'm trying to implement sync write and am running into some problems.

I am sending to 4 servos (id 1:4) to address 32 (0x20) with a value of 1023 (0x03ff) to each one. My command packet is as follows...
ff ff fe 10 83 20 4 1 ff 3 2 ff 3 3 ff 3 4 ff 3 38

The command is successfully sent but the servos dont start moving (I have them set for continuous rotation) If i set them all individually, it works great (although much slower)

Any clues as to where my command packet is wrong?

Thanks,

Nate
