I am currently working on a demoboard with the ADV7623 but the final product will use the ADV7626.
I overlayed on a screen a few black fboxes with green border but I would like the black to be transparent and keep the green border.
If register 0x0 from OSD Map is set to 0x80 (Enable OSD, 100% transparent) the whole fbox is transparent, even the border.
On the BLIMP software, for ADV7625/ADV7626, it is possible to set the color inside color to transparent and keep the border visible.
Is there a specific value to change the inside color of the fbox from black to transparent?
