I need to confirm the design for the pins used on a rsr232 com port. I have confirmed pins 2,3,4,5 are used where a risistor is shorted across 2 & 4 to be the red wire and 5 is black for ground, 3 is white.
Please share your thought on what ohm resistor is to be used and any other advice you can share.

Thanks

mark

Currently I have a program written in Labview to control the motions in the RCB-3J. Hopefully this week i get a CMUCAM3 camera with a ARM7 so I can write it in C.

I want to program that ARM7 to control the RCB-3J (KHR-1HV) to find, walk, track a football autonomous.

What I used for this:
See page 8, 9 and 19 (the commands i use)

Open a serial connection to the RCB-3J
Send 1 byte: 0x0D
Receive 1 byte: 0x0D (you know that the RCB-3J is there)
Send 4 bytes:
CMD = 0xF4 (see page 19)
OPT = 0x05 (used a serial monitor for this code, page 9 explains it)
NUM = Motion number (see page 19)
SUM = (CMD + OPT + NUM) & 0xFF; (used a serial monitor for this)
Receive 1 byte: 0x06
Close the serial connection to the RCB-3J

The checksum isn't always 0xFF, there are commands that don't use bit 7!
And the time to receive 0x0D and send a command should be minimal, there is a time-out in the RCB3J.

Who here has interfaced to the RCB-3J using 3rd party circuit?

For example using a PIC, STAMP or Audrino board to send instructions to the RCB-3J?

I have a copy of the reference guide, though I would prefer not to reinvent the wheel, so I'm hoping to leap frog from other's experiences?

Michael
