I think there's gong to be a big queue for this one when it's ready!
Project: HDMI/DVI out for STFM
Re: Project: HDMI/DVI out for STFM
am looking forward to getting one.
Re: Project: HDMI/DVI out for STFM
I just tested the HDMI mod board sent by Icky - after finally obtaining a 32MHz oscillator which I originally didn't buy for my H4 - and it works perfectly. Completely stable so far, no "jiggling" effect. Thanks @Icky!
Re: Project: HDMI/DVI out for STFM
Sure would be great to get one! It doesn't need to be perfect. Sounds like this version would meet my needs.
Re: Project: HDMI/DVI out for STFM
@Smonson - great news. Now we have a platform to continue building on with the H4 and the FPGA Shifter board
Re: Project: HDMI/DVI out for STFM
As there are a few boards out there now for testing thought I would put up a guide on how these currently work.
Using the board on the H4 it plugs into the Shifter socket but there is also a VSYNC pin that is exactly in line with the VSYNC on the H4 motherboard. That pin should have a single socket to plug into. If you already have a VGA port or ST Monitor port soldered into your H4 then you will have to stack the board with DILs and you can put a wire from the VSYNC point down to the VSYNC on the H4.
The three LEDs marked show the frequency of the display being shown i.e. 50/60Hz for Low / Med and 71.2Hz for Mono.
JP1 - this jumper allows you to alter various setting on the board:

JP1 - this jumper allows you to alter various setting on the board:
- Yellow - 0 = Borders, 1 = No Borders
- White - 0 = 4:3 ratio, 1 = 16:9 ratio
- Green - 0 = No scan lines, 1 = Adds old CRT looking scan lines
Borders | Ratio | TV Res |
0 | 0 | 800x480 |
0 | 1 | 480p |
1 | 0 | 720x400 |
1 | 1 | 640x400 |
Re: Project: HDMI/DVI out for STFM
As you've seen, my board is up and running in the H4. I've briefly verified that it's not fully compatible with my fullscreen routines - is there some knowledgebase I should start off from or should I just start to document function vs expected?

Re: Project: HDMI/DVI out for STFM
Might be best to start a new thread on it. As @Icky likely mentioned, we want to make this FPGA shifter fully compatible with the original.

Re: Project: HDMI/DVI out for STFM
Got my test board hooked up today.. Great work by @Smonson and @Icky
