Thanks guys,
1) I'm generating black, white, Hsync, Vsync with '2bit DA'(and grey,but can't use it)
2) Any PIC from family PIC16 (currently PIC16F84 because mostly code is for this PIC), frequency is 12MHz, that means one cycle 0.33..us
I don't understand "interrupt of *constant* timing", I wrote part of code to generate 4us for Hsync, then 8us delay(black) and 52us of data(white and black).
More simple can't go ,but it just isn't working.
I tested every part of code and it has perfect timing. (if 12MHz is 12MHz)
3) Well I'm going to use when finished interlacing because of flickering. Now I'm at half of PAL, like said 312 scanlines.
4) I don't know what equalising pulses are so that could be a problem.
5) Tried but it's not working, probably I should use directly TV and not simulator.
6) Ahh, I realized it's in my nature to torture myself.
