Servopod and serial connection

[knight]

Hi! I need to connect my CMUcam to my Servopod via serial port, i use the SCI1 to do this, but i need to pass at the cmucam command like "GV 20 30 12" how can i do that?
in isomax manual there is only a simple example about an hex number, nothing about array or phrase!!!
please write me back soon with the solution!

For your reference, here is the link to a program that Randy has written for one of the CMUcam. I am not sure which cam model it is. Please read the comments.

I, i would like to connect my CMUcam2 with my Servopod, i don't know if it's better to use a serial connection or an other type, what do you think about it?
I need to comunicate with my cmucam in this way:
pc-->(linked to) servopod-->(linked to) cmucam
My main quest is to create a little isomax program to use cmucam as a sensor like this:

anyone can help me?
I hope so!

Do you have this connection & a comment/uncomment on the highlight code below?

For ServoPod make sure to comment out the line above, and uncomment the line below

Thanks a lot, now it works very good!

Only 1 command i find that doesn't work: SV
This is my screen view:

:SV 2 100 SV 1 »72
SV ? STACK EMPTY
NCK

the SV's line of code are:

\V2 2 MAKE:MSG SV EEWORD
\ : Servo_Position SV ; EEWORD
( servo# 0-4 postion 46 - 210 SV

Have you made any other programs for servopod and CMUcam ?
Thankyou very much I really appreciated your help!

I remember there were a couple commands I that just didn't make sense to me. I concluded the documentation must be off. Thought everything was resolved though. Don't really remember. It's been a year since I wrote this program and used if very little since.

No, this is the only program I wrote for the CMU Cam. I did consider how to apply it, such as making a predictive line follower, but never tried the ideas out. I had borrowed the CMUCam V2, so I had to return it. I own a CMUCam V1.

There are many other examples of programs for the various 'Pods though in the appnotes under the 'Pods Downloads page.
