Description
The RGBtoHDMI interface converts the "digital" RGB video signal from the Amiga to HDMI compatible with most modern TV/Monitors. The interface comprises a Raspberry Pi Zero and a specially designed Hat containing a few basic logic chips. Custom firmware on the Raspberry Pi, in conjunction with the Hat, is able to correctly sample each of Denise's video modes to give a pixel-perfect rendition.
This version adds the ZD pin for genlocking with a 12-bit frame buffer on the Raspberry Pi (like the AVideo/12 or OpalVision cards). It also includes the probably unnecessary 47pF capacitor from the Amiga 2000 version.
