camera delays

[MOUNTAIN747]

I am converting my old digital camera into a time laps camera using an 8 bit dip switch on PortB of a 16F84A to set the delay between frames. I want to use the Sleep command for delay times longer than two seconds. PortA will control the camera trigger switch, and for longer delays the power switch is controlled. I thought my code looked good until I tried to compile… So much for looks!

I get these Errors in the Select Case portion of the code;

C/pbp/pbppic14.lib 47 : [226] Numeric Constant or Symbol Name Expected
C/pbp/pbppic14.lib 47 : [201] ‘)’ Expected

These two error lines show up numerous times in the Select Case portion of the code until the last line says “too many errors”.

I have looked over Select Case command and I can’t see any problem. DelayMode is a Variable for PortB; Smode is a Word Variable to be used with the Sleep command. Sleep command line is not committed in the error messages. Got Me!
I'm know I haven't set the Header yet but I don't think that should be a problem at this time. I hope someone can spot some stupid error I overlooked. Comments please!

Just in case your camera happens to be a Canon, there's an elegant software-only solution that would give you an intervalometer and a lot more.

Compiles without error here.

Which version of PBP are you using?

After two hours of trying to solve the compile problem (with PBP2.60) I posted my question and turned off the computer for lunch. On return I read DT's comment and tried again. This time it worked (which now concerns me). Man, Darrel your good! I have no idea what happend beside loosing two hours. I guess the hard drive has polterbytes. Thanks again guys for your comments, and yes it is a Canon. I'll give the site a look.

and yes it is a Canon. I'll give the site a look.

In fact, I'd urge everybody on the forum owning a Canon to check this out; its fantastic. Remote shutter control, motion detection, ultra high speed, loong exposures, time lapse, bracketing, the works. And the tool is scriptable too.
