CPS2 digital AV interface (Rev 2)
cps2_digiav is an add-on for Capcom CP System II arcade board which enables digital video and audio output via HDMI connector. The project consists of an interface PCB and FPGA firmware. The board can also be installed on CPS1 and CPS3, see respective branches of the project.
- framelocked email@example.comHz output with max. 40 scanline latency
- 24bit/48kHz audio output
- resolution select
- more scanline options
- settings store / profiles
The add-on PCB can be installed inside of CPS2 A-board. The following additional parts are required:
- 2pcs BCS-105-L-D-PE-BE sockets
- 2pcs 2x5 U-type pin headers
- ribbon cable (~25cm, at least 3x4=12 conductors)
- coaxial cable (~40cm)
Signal hookup points are listed in pcb/doc/cps2_hookup_points.txt and instructions are in pcb/doc/install.md .
Board is controlled via CPS2 volume buttons on the side (which do not affect digital volume level):
- VOL-: change vertical offset (0-8, default=4)
- VOL+: enable/disable scanlines
