Hello,
I purchased an RPI5 and composite output improved a lot, thank you RPI foundation very appreciated. Image quality is really good, and I am able to fill the screen almost 100% on 400x240.
I have 3 questions:
1)What can be the proper dac for CM5 composite output over DPI?
2)Is it possible to output csync from DPI pins if I wanna use DSI to generate the video? Combining Hsync and Vsync isnt really stable. Or is it possible to combine Hsync and Vsync with PIO pins(progressive scan)?
3) There is a tool called lrmc https://lrmc.sourceforge.net/ which can calculate low resolutions for ntsc pal cga etc, I was able to compile it on pi. Is it possible to add it official repositories?
