Blackmagic Forum

Hi,
does someone have an arduino sketch to use with the Blackmagic SDI shield to control BMSC Iris with a potentiometer?
As I`m an Arduino beginner user any help will be very useful
Thanks

Hey Beto,

I guess you want to use a kind of fader for focus pulling? Or do you have another use or setup in mind?

Currently I'm using the joystick setup for this kind of settings. But I know that the guys from SKAARHOJ have build a board with a fader so they probably have some lines of code for it, although I could imagine that the sketch shouldn't be too different from the joystick sketch itself. Although, being a Arduino beginner myself, I can't guarantee it.

Looking forward to seeing some sketches incoming as I could also imaging myself implementing a fader in my setup of Micro Studio Cameras.

Wish you good luck!

do you still need it?

Thanks,
Yes I still need it.
I received a replay a couple of days ago, but unfortunately the schetch is for zoon control.
Thanks

"OK, here is your gift.

Arduino people believe in helping learners, if you show your are putting effort in the they will help.

If you just want someone else to do it then they will be silent, just like all others on BLackMagic forum.

If you have software brain then all this info is in BlackMagic Arduino shield guide, attached and in Arduino websites.
With 12 hours work you will have got to this point already.

I give you this info to assist, you face several challenges just installing arduino and th e Black magic library.
Have fun, if you just want someone to do it then you will have to pay someone for thier time.

Read th e readme file..........................!

Regards Maurice"


I send it to you by email

Below you have an arduino sketch to control up to two cameras with only an SDI shield. As you can see I`m not an Arduino expert and probably the sketch could be improved. Please feel free to comment it and make changes, and I hope it could be useful for someone.
Somebody know if the Shield could work with the arduino Mega?
I`m working in an sketch to control more them two cameras with only one SDI Shield, and my go is to use digital arduino ports with encoders. Somebody cam help me?
thanks

Hi

You can also find some information for the Arduino code at: http://skaarhoj.com/designs/diy-items/d ... di-shield/

We have also made a shield kit including a fader.
