• https://github.com/hydrausb3/hydrausb3_hw
  • hydrausb3_hw repository contains details about HydraUSB3 V1 devkit

• https://github.com/hydrausb3/riscv-none-elf-gcc-xpack
  • Open source RISC-V toolchain for WCH CH56x (thanks to David Carne / davidcarne on GitHub)
    • Based on xPack GNU RISC-V Embedded GCC v12.2.0-1 with support of WCH RISCV CH56x... "WCH-Interrupt-fast"
  • See Pre-built toolchain for Linux/Windows on https://github.com/hydrausb3/riscv-none-elf-gcc-xpack/releases/tag/12.2.0-1

• https://github.com/hydrausb3/hydrausb3_fw
  • hydrausb3_fw repository contains open source test firmware / examples for HydraUSB3 v1 devkit using WCH CH569 MCU
• https://github.com/hydrausb3/wch-ch56x-bsp
  • wch-ch56x-bsp repository contains open source code for WCH CH565/CH569 BSP with basic libraries(mainly drivers) mainly used for HydraUSB3 v1 Hardware.
• https://github.com/hydrausb3/wch-ch56x-lib
  • wch-ch56x-lib repository contains open source library which provides USB3, USB2, HSPI and SerDes drivers that have been tested using the benchmark/integrity tests in tests/.
    • It is based on wch-ch56x-bsp but its goal is to provide a higher level library mainly used today by HydraDancer/hydradancer_fw.
    • As HydraDancer was using several peripherals at a time (USB3/HSPI, USB2/HSPI), an interrupt queue was implemented to avoid missing interrupts for use with HSPIDeviceScheduled along with a static memory pool.
    • While the tests in this repository are simple enough to do the processing inside the interrupt handlers, Hydradancer was missing interrupts and deferring interrupts to user mode was required.

• https://github.com/hydrausb3/wch-ch56x-isp
  • wch-ch56x-isp is a open source small utility(Windows/Linux) to program WCH CH56x micro-controllers over USB (using WCH56x ISP bootloader).
• https://github.com/hydrausb3/hydrausb3_host
  • hydrausb3_host repository contains open source host tools (for Linux & Windows)
  • The aim is to use host tools with hydrausb3_fw USB Examples (mainly related to USB2 or USB3 examples)

• https://github.com/hydrausb3/wch-ch569-serdes
  • wch-ch569-serdes repository contains details about WCH CH569 SerDes to interface it with FPGA...
