  • Calculators:
    CFX-9850CG PLUS

Posted 08 February 2010 - 09:48 PM

Hi! I joined this forum for one, sole reason: I want to turn my CFX-9850CG PLUS calc. into an intervalometer for my camera, and I need a program to send a signal to my camera via the connection cable.

I have read way too many tutorials on how to do it with TI calculators, but I've figured that they are using different programming languages (duh!)

I anyone can help, I'd be really happy!

I would really like to see a program for the fx-7400G!

Okay, I've done a little bit of thinking. Supposing you have figured out how to connect the three pin cable to the camera, here is a program that sends a signal through the cable, to the camera. Note: this is a basic program for the fx-9860 and compatibles , not cfx.

'T=time 1800=1sec 
1800*(put # seconds here) ->T
Do 
T-1 ->T
LpWhile T>0
OpenComport38k
Send38k 1
CloseComport38k

This program sends a signal through the 3pin cable after the number of seconds has expired.

Sorry, I thought you wanted a timer for your camera.I just googled it and found this: http://www.instructa...n-Intervalomet/ Here is a program that takes pictures every n seconds like the TI in the article. In fact, it is almost the same code. Note; this program works exactly like the one in the TI article.

A=? ->A
Lbl 1
Do
A-1 ->A
LpWhile A>0
OpenComport38k
Send38k 1
CloseComport38k
Goto 1

This code is only slightly different, and takes a specified number of pictures.

Time=? ->A
Number of pictures=? ->B
Lbl 1
B=0 => Stop
Do
A-1 ->A
LpWhile A>0
OpenComport38k
Send38k 1
CloseComport38k
B-1 -> B
Goto 1
