README
hardware/rgb-composite/README.mdThe reason why AD724 is not suitable for this application
From datasheet:
The AD724 can be used to convert the analog RGB output from a personal computer’s VGA card to the NTSC or PAL television standards. To accomplish this it is important to understand that the AD724 requires interlaced RGB video and clock rates that are consistent with those required by the television standards.
That's the case. STM32 LTDC can't output INTERLACED video signal.
