Sony LanC Program
I have a starter program for Sony Lanc posted, with docs on Lanc using PBP ( the top two programs ) if anyone is intrested. this is done in bit banging and can be adapted to loops with some timing changes. all you need is a camera (video / Still ) one resistor and a pic chip.

If anyone tries this program please report your results and your
camera's make/model. Have improvements report this also.
Thanks Larry

I have spent a few hours on this and the only way that I can even get it to work sometimes is: read and write with the same pin
This is the way my Lanc controllers that I build work programmed in assembly.
or the one I built using the elm interface chip.
using your starter 33 is the only hex that will record or stop
on mine I can use 27 or 33 record and 29 or 33 stop not sure what that's all about.
right now IF it does start recording some times it will flicker between rec and standby. I will try to work on it some more and post were I'm @
I have 5 different Sony corders I use one a mini dv and they are all interchangeble on my board
thanks for working and sharing this and I hope what I have posted helps

Ok sounds like you changed the program some to test different hex commands?
You need the two different pins portb1 and and portb2 one looks for interframe gaps and startbits the other sends commands did you use the pulldown resistor on Portb1 and did you use two resistors one for each pin to the lanc line and of course ground I did it this way for testing so I could put the scope on either lead and check for pulse voltage. I found sometimes I needed the pulldown resistor to get clean pulses that would go 0 to 3vdc not 1.3 to 3vdc. Thanks for testing this, sometimes no matter how much you work on something, when someone tries it, it may or may not work and this is what I wanted to see.
Now try the program as written turn the camera on first then turn the pic on the camera will shutoff wait 10 seconds turn on wait 10 seconds record wait 20 seconds stop record wait 10 seconds and turn off and go through all this again Im using a DCR-HC20 sony camera. I listed the commands that worked with my camera. Let me know what happens.

I have my camera on the desk Im using a BS2 to read the data stream comming from the camera and It works using serin 9600 and reversing the hex
' {$STAMP BS2}
' {$PBASIC 2.5}
value VAR Byte(8)
syncbyte VAR Word
a VAR Byte
a = %11111111
start:
Sync_byte:
syncbyte = 0
DO WHILE syncbyte < 3200
PULSIN 1, 1, syncbyte
LOOP
SERIN 1,84,[value(0),value(1),value(2),value(3),value(4),value (5),value(6),value(7)]
DEBUG HEX value(0)^a,TAB,HEX value(1)^a,HEX value(2)^a,HEX value(3)^a,HEX value(4)^a,HEX value(5)^a,HEX value(6)^a,TAB,HEX value(7)^a,CR

Sorry no luck
I even tried it with my hc42
the only thing different is I'm using a 16f676 XT_OSC @ 4
were you @ 10
right now I'm trying to keep all my camera in the woods. I ran and got a couple to help you test.
I maybe out of pocket next few days with will try to do more testing later

Grounded Thank you for testing the setup.
I also tried it and it would turn off and turn back on but nothing else, so I started looking at the program and in the power_on sub you will see at the bottom the counter value is 300, counter is a var byte so it would never return to the program. I use this value when looking at the data stream on the scope this keep the loop running and made it easy to see my timing I could do this at each step.
So I guess you have to take them out when posting the code MY BAD.
its things like this that make a project take longer than you expect!!!
I reposted the correct program take a look when you get a chance
Thanks Again Grounded

Maybe their not being used that was a test of a second command byte
command_byte2 can be removed along with record off hex 29
record on also will stop recording.

OK
just let me know when and were you post the corrected code and I will try to test for you
Thanks for working and sharing this.
My Lanc controller programed in assembly and using 1 pin to read and write
works great. But just being a hobbyist programmer figuring out the pieces
to do this with PBP would help me learn
so again thank you for letting be apart of this

Thanks Grounded this works great for me, I added a timer and commented out the line that calls it I have my camera set up outside and will be taking movies every hour for 10 seconds. The Code below should be good for testing, the code as is should cycle through, Camera Off, Camera On, Record on, Record off, Camera Off then back through.
turn the camera on first when you power the pic it will turn off the camera.
I am not using the pull down resistor at this time and I am using 1k resistors from pins 1,2 to lanC line, and yes once you get it running use one pin for both.

Yep
that about how I run mine
power up pic & camera it take a 10 sec. test movie then powerdown
until INTERRUPT from PIR
change 470 res. to 1k on each pin .no pull down res.
I will try to test for you by 2morrow afternoon and post
thanks

Sorry but I'm just not having any luck with this.
look this over and see if I missed anything.
hardwire:
1k resistor from portc.5 to Lanc line
1k resistor from portc.4 to Lanc line
Lanc ground to system ground
put the PBP code in and nothing
I can drop in my assembly code in and lift portc.5 wire it works
it 's got to be that the PBP timing is off but I don't have a scope to check
after playing with this Lanc stuff for about 2 years let me share some of things I learned the hardway.
1. this one cause me to lose more hair than all others put together
the Lanc line can backfeed a small amount of voltage to the chip
which can and will keep the program running with supply to the chip turn off
which means that cycling power may not reset the program to the begining
what I do is use a double pole power switch that not only kills power to the board but also opens the lanc line
2. 27 record and 29 stop are listed under special commands
2827 and 2829 none of my cameras with work with this
BUT THEY WILL WORK USING 1827 & 1829
3. I put my cams to sleep with 185E and wake up with the standard pulse lanc line low then send the record command I have never had to use the
185C power on command ( on my command sheet it list 5c but does not
tell what it is .
4. I think most people that does this shift 48 to 52us to read and write in the middle of the bit
maybe some one else on the forum can come up with some answers
Sorry I could not make it work

I ran it today and my camera would turn off only, nothing else, Yesterday everything was working great. Then I remembered why I used two pins while setting this up. So I installed a 20k resistor from stamp pin b1 sync pin to ground and everything started working perfectly. I used two pins because I did not want to pull the sending line low, my scope showed only 3vdc on my camera not the 5vdc I expected.

2. 27 record and 29 stop are listed under special commands
2827 and 2829 none of my cameras with work with this

Yes I found the same thing remember the command_byte2 that I said was not used that was hex 28.

3. I put my cams to sleep with 185E and wake up with the standard pulse lanc line low then send the record command I have never had to use the
185C power on command ( on my command sheet it list 5c but does not
tell what it is .
I understand, and have not tried this yet ( but will ) when setting something up I always use the full steps first, and then take the shortcuts later I would not be sure it works with all camers or not.
grounded
4. I think most people that does this shift 48 to 52us to read and write in the middle of the bit
Your talking about sending data to the first two bytes, not sending right after the syncbit but waiting until the middle of the 1.4 ms frame and sending then. I have a sinc_bit which looks for the camers syncbit and sends right after it finishes so my timing is right on not just sending somewhere in the middle. But when using a different osc 4mhz and not 10 mhz it could be too tight for a slower speed and this is something I need to check.
Now let me ask this Did you camera Power Down when you first turned on the pic's power. there is no delay so if the camera is not on and the switch between the camera and pic is not on and the pic is powered it will go into limbo and do nothing. So everything must be on then power the pic it should turnoff the camera immediately and be in sync.
|
Larry no the cam did not turn off, it just "did nothing"
But I really be leave the problem is in the tight time this needs and my 4mhz
maybe my problem with using PBP code. I no were near smart enough to know the if, &'s and butts of this but I have been told more than once that because of the timing you could not do this with PBP but I'm sure hoping that you
are someone here will prove then wrong

I don't know whats wrong! I do indeed have it running right now, It has been running all day taking pictures every 15 minutes for 5 seconds at a time. PBP does indeed work and the timing is really not that tight. I did notice your using xt setting I have always used HS mode, have not looked over your program much yet. I see no reason that 4 mhz would not work.

up and running
Larry 676 does not have hs_osc so it would not compile thanks for trying
BUT:
I'm up and running (cross fingers)
remember I said something about adjusting to midpoint of the bit
well I did 'Command_byte:you had dropped it from104 to 80 to adjust timing
I dropped to 60 (about half) and bingo it's running (started@ 70 and it ran)
I think 80 is right on the edge that's why sometime it work and then the next
it did'n
and this is with my standard Lanc control board using
1 pin to read / write no pull up or down 60 ohm resistor in Lanc line
this basic program just start recording 10 sec. movie then stop wait
5 sec. and start over. If it will run one command it should run ALL
it's been running for about 2 hr. with out missing abeat
Now the bad news the next few days are full full full . not sure it I will have time to eat much less to play I mean work on this
I would be interested to know how it looks on the scope

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
