port to cheaper fpga? #15

Open joveaaron opened 1 year ago

joveaaron commented 1 year ago

this dev board is hard to find and if you made an opl3 board this would be very hard to solder a port to a cheaper fpga would be very useful

what I am trying to say is that an fpga functioning identically* as a ymf262 (pinout of fpga ymf262 exposed) is the real deal, so things like the commander x16 don't have to source old stock of opl3s

like a modern replacement, you solder an fpga on a board then solder the board to the place where the opl3 should go

I am so silly, deleted my previous answer, thought this was a completely different repo...

Maybe something like this: https://wiki.sipeed.com/hardware/en/tang/Tang-Nano-4K/Nano-4K.html

You can get these from aliexpress for like 10-20 bucks. I need to look into the tool chain this device has.

Do you need HM ARM?

If not, we'd strongly recommend going with the 20K LUT device. That one is a SIP that also comes with 8MB SDRAM. We have a ton of positive experience with it and have already paired it up with a premium I2S/I2C audio CODEC, see WM8960
