i downloaded dueVga and tried to crate compose video  signal, i wired in a protoboard following below diagram:

https://stimmer.github.io/DueVGA/tvout.html


after that i loaded DrawingTestNTSC example in arduino ide and upload it to arduino due
i am seeing some kind of squares, rectangles, triangles, but in black and white with interference, on the header of that example it says something like:

// VGA.beginNTSC starts a 320x200 NTSC colour mode
// Output via an R-2R ladder on pins 34-41 (34=LSB 41=MSB)

so on the diagram im using due pins 36 - 41, but above comment is saying use pin 34? to 41, then what is the correct wiring for that?

thanks in advance.
