Generate a linear timecode ( video application )

[Mathy]

Hi,

I'm looking for generate a timecode who I can put into an audio input.

This wiki give the explanation : http://en.wikipedia.org/wiki/Linear_timecode

But it's chineese for me. I don't know how to code the Biphase Mark code et how to update the 80 necessary bits.

If somebody can explain to me how to begin this thing in Flowcode, that will be very nice

Thank you for your help

Hello Mathy,

You could use 10 byte variables or an array of 10 bytes and then begin by clearing the bytes and then using OR and AND to put in the data you need. It should then simply be a case of shifting out the bytes on a output pin at the right frequency during the screen blanking.
