Sony LanC Program

I tested using 60mS and yes it worked for me also, I also tested not using the power on command and issuing a Record command after a pull-down wakeup it also worked.

looks as if I was on the edge @ 80 if I can find a 4mhz board around I will test the 80 using it, so if 60 to 80 works maybe lower then the timing is not so critical I guess!

Thanks for your help in working this out now MANY can enjoy

You would think I would know how to spell TESLA by now

I dropped the PBP LanC read/write in to some of my generic PBP camera code
because I was able to read/ write with 1 pin like I do with the assembly code
I could just drop the PBP version in the 16f676 and the camera is up and running
thanks

Code:

this looks very cool guys!

I hope I can test drive some of those routines soon.(used the ELM lanc chips in the past).

I see that it write, but does it read LanC too?

cheeers!

Flipper
I have read LanC using a basic stamp and 9600 serin command so it could be implemented
