Video Camera Control (VISCA) with BS-2

BGardiner

This is the first time I have used a Basic Stamp.

I have written the program, and it outputs data in the debug screen. When I connect the stamp to the camera, nothing!

The camera is an EVI-D70. It wants hex sent to it. I am sending it from the serial port on the homework board. Below are the·four lines that initialize the camera:

SEROUT 16, 16468, [noparse][[/noparse]HEX2 136, HEX2 48, HEX2 01, HEX2 255]
PAUSE 1000
SEROUT 16, 16468, [noparse][[/noparse]HEX2 136, HEX2 01, HEX2 00, HEX2 01, HEX2 255]
PAUSE 1000

Again, it outputs the hex on the debug screen, but will not communicate with the camera.

Thanks for any suggestions.

The camera probably doesn't want hex. It probably wants the actual byte values. Try taking out the HEX2 and see what happens.

BGardiner

So, you mean like this sending the hex values as ascii?

SEROUT 16, 16468, [noparse][[/noparse]"88,72,01,FF"]
PAUSE 1000
SEROUT 16, 16468 [noparse][[/noparse]"88,01,00,01,FF"]
PAUSE 1000

BGardiner -

A HEX constant is specified by preceeding the HEX representation with a $ so that PBASIC knows it's HEX and not ASCII.

Try this:

SEROUT 16, 16468, [noparse][[/noparse]$88,$72,$01,$FF] 'Send 4 HEX constants
PAUSE 1000
SEROUT 16, 16468 [noparse][[/noparse]$88,$01,$00,$01,$FF] 'Send 5 HEX consstants
PAUSE 1000

BGardiner,
I did mean that you take out the HEX2 and leave the rest like: SEROUT 16, 16468, [noparse][[/noparse] 136,48,1,255 ]

BGardiner

The camera documentation shows that the camera wants the hex code not the decimal.

Attached is an example of the code format....

Mike,

It is working now, thank you, your instruction proved to be correct after I fixed a pin-out problem.
