Re: SidPi project C64 sound chip (SID 6581) and the Pi's GPI

Also looking at adding some more caps and connecting up the ext in order to reduce noise.

Still sounds pretty good some captures can be found here

Re: SidPi project C64 sound chip (SID 6581) and the Pi's GPI

Hi Cool thanks rga24, I'm an electronics novice so I just followed the reference spec, I had a few boards made up (with the mistake) but I managed to fix them with some creative wiring. You can order the correct boards from here ... https://oshpark.com/shared_projects/vRw7mWuD there is a minimum ord...

Hi Jeff

Did you get it to compile ok? If not I've added the a pre-compiled sidpi.ko into git hub, hopefully this will work.

Re: SidPi project C64 sound chip (SID 6581) and the Pi's GPI

Hi Jeff, You'll need to download the kernel sources from github here https://github.com/raspberrypi/linux . I have some work todo on the build scripts to install the module. But you can compile the and run the server (as root) without the module. I've updated the README to reflect how to do this. As...

Re: SidPi project C64 sound chip (SID 6581) and the Pi's GPI

Sure, feel free to have some printed and thanks for your interest and the redit post :D It did feel good when it all came together both hardware and software. I'm ordering my own soon, but I'm a bit nervous as I'm no expert. Its on a prototype board at the moment and when there is no sound there is ...

SidPi project C64 sound chip (SID 6581) and the Pi's GPIO

Check out my mating of a SID and a Raspberry Pi - SidPi was born! https://www.youtube.com/watch?v=plyVYZ6XPwQ Used the GPIO to connect to the address and data pins of the SID, they are one way so no need for any voltage conversions. Implements the HardSid protocol and the ./dev/sid device so works n...
