Here is a list of [boards already supported by the examples](gateware/boards). - Get started with some [example DSP cores](gateware/cores). Examples include calibration, sampling, effects, synthesis sources and so on. The design files can be synthesized to a bitstream using Yosys' [oss-cad-suite](https://github.com/YosysHQ/oss-cad-suite-build). + +## :notes: Project Showcase :sparkles: + +- **[FPGA-based neural-net waveshaper](https://matpalm.com/blog/wavenet_on_fpga/)** - (from [matpalm@](https://github.com/matpalm)) +- **[Daisy Seed TDM for Eurorack PMOD](https://github.com/heartwerker/daisy_seed_tdm_eurorack_pmod)** - (from [heartwerker@](https://github.com/heartwerker)) +- **[`apu_chord` core](https://github.com/proppy/eurorack-pmod/tree/apu_chord)** - (from [proppy@](https://github.com/proppy)) + +A couple more from me: + +- **[8-channel USB2 soundcard](https://github.com/apfelaudio/eurorack-pmod-usb-soundcard)** - mostly in Amaranth. +- **[Real-time DSP with Rust on LiteX](https://github.com/apfelaudio/eurorack-pmod-litex)** - mostly in Rust/Migen. + + # R3.3 hardware details ![labelled eurorack-pmod 3.3](docs/img/r33_labelled.png) @@ -104,13 +113,7 @@ The project is split into 2 directories, [`hardware`](hardware) for the PCB/pane # Manufacturing -**R3.3 hardware is in stock** [order **here :)**](https://apfelaudio.com/) - -~~Update: R3.1 SOLD OUT, revision R3.3 will land in the next 1-2 months - [get notified **here :)**](https://apfelaudio.com/modules/pmod/)~~ - -~~Update: R3.1 (first production release) is fully functional with 1 rework, see github issues for up-to-date information.~~ - -~~Note: I gave some R3.0 (preproduction) units out at Hackaday Berlin '23. These are tested but NOT calibrated. They had 2 hacks applied. Some inductors are shorted with 0 ohm resistors as the wrong inductor was populated (means the board is a bit noiser than it should be - but still definitely useable). Also the reset line of the jack detect IO expander was routed incorrectly, so I manually shorted 2 pins of that chip. Functionally these boards are the same as R3.1, which fixes these issues.~~ +## **R3.3 hardware is in stock** [order **here :)**](https://apfelaudio.com/) # R3.1 Hardware (no longer manufactured)
