Hello !
I´m new to Propeller and want to know if someone of you tried to
hookup an propeller to an Arcade CRT (15khz) / 60 hz
I have played around with the ntsc TV Objects and now I want to use an vga object
(rgb analog) to the arcade crt.
Either I modify a TV Object (DodgeKong) to behave like VGA (since I need the 3 Analogs rgb lines)
or modify a vga object to put out a 15khz Sync (compsync)
did someone like this before ?
I ´m confused how to tell the freqA register to put out a sync every 15khz.
cheers

Note: with the Propeller Video Generator, you (generally) configure PLLA to generate the dot-clock frequency. The video driver then generates the sync signals by controlling specific pins (via WAITVID). It's all very low level.
