HEL_GFX_Driver 5.0 for GG Platform/Demo Board etc.

blittled

I am converting the HEL driver for the GG platform and I have video working but the signal does not appear to be in synch. Has anyone converted the HEL driver for the Demo Board settings? I have used;

_clkmode = xtal1 + pll16x                                               'Standard clock mode * crystal frequency = 80 MHz
_xinfreq = 5_000_000

 VIDEO_PINMASK    = %0111_0000        ' vcfg S = pinmask  (pin15 ->0111_0000<-pin8), only want upper 4-bits
 VIDEO_PINGROUP   = 1                        ' vcfg D = pingroup (Demo uses group 1, pins 12-15)
 VIDEO_SETUP      = %0_11_1_01_000 ' vcfg I = controls overall setting, we want baseband video on top nibble, 2-bit color, enable chroma on broadcast & baseband
tvport_mask   long      %0111_0000 << 8         ' Demo DAC is on bits 11, 12, 13

Am I missing something?

Here is a driver for the C3 which is the same pin configuaration as GG boards

Thanks Roadster, that is exactly what I was looking for.
