I have identified some issues in the current firmware that I think must be resolved before I can release anything. This mostly has to do with cycle based emulators, bus timing, digiplay and usb timeouts. I need to get rid of some unnecessary overhead. Vus timings from buffer to SID are fixed and exactly as specified in the datasheet. Anyone with tips is welcome to contact me. Due to this I haven't had time to finish the final board version yet. The current firmware does work for normal emulator use, asid play and midi (although not finished yet).
USBSID-Pico is a RPi Pico based board for interfacing one or two MOS SID chips and/or hardware SID emulators with your PC over USB.
- Supports all MOS SID chips e.g. MOS6581, MOS6582 & MOS8580 (untested)
- Supports all SID chip replacements e.g. SIDKick-Pico, SwinSID, ARMSID (untested), FPGASID (untested)
- 1 MHz oscillator (external optional)
- if no external clock is detecten will generate a 1 MHz square wave using pio
- if an external clock is detected will read the external clock signal
- Power via USB
- 5v stepup for clean 5v VCC to both SID chips
- 12v or 9v stepup for clean VDD to both SID chips
- 12v/9v jumper, defautls to 12v ~ inspired by SIDBlaster-Nano design
- Audio out filter as in the C64 schematics
- With optional 8580 cap
- Audio jumper
- SID1 audio left & right
- SID1 audio left & SID2 audio right
The firmware is still in development
- Custom protocol for playing SID files or usage with emulators
- An adapted version of Vice emulator is available via de link under examples
- SidBerry for command line SID file play is available via de link under examples
- More to come?
- Midi (in) ASID support (heavily inspired by multiple sources ~ links to follow)
- Midi support in development
- WebUSB support in development
- Single or dual SID support (firmware specific)
- Remaps known SID addresses to $D400 & $D440
- Dual, triple or quad SID support with SIDKick-Pico (firmware specific)
- Remaps known SID addresses to $D400, $D420, $D440 & $D460
- Quad SID support (addresses remixed) with SIDKick-Pico (firmware specific)
- SID2->SID3 SID3->SID2
- Onboard LED acts as VUE meter calculated by the voices of SID1
- Onboard RGB LED acts as second VUE meter calculated by the voices of SID1 and SID2
- Requires Black Pico clone board!
- Uses the TinyUSB stack
While in development any examples will only work on Linux.
Chrome webbrowser ASID is supported in Linux and Android.
