You can add this software package directly on the IDE through the Arduino Boards Manager.
Add the following link in the "Additional Boards Managers URLs" field:
https://github.com/openwch/board_manager_files/raw/main/package_ch32v_index.json
Then you can search for "wch" through the "board manager", find the installation package, and install it.

Note Testing
Cargo is the package manager for the Rust programming language. It is included by default when you install Rust.
Installing Cargo and Rust
To install the Rust package manager (Cargo), follow the instructions for your operating system:
-- Linux and MacOS
curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
Closed and open Check if the installation worked:
cargo --version
-- Windows
-
Download the installer at https://www.rust-lang.org/tools/install and run it.
-
Open the command prompt and check the installation with:
cargo --version
- If it does not work, manually configure the environment variables:
CARGO_HOME=%USERPROFILE%.cargo
PATH=%CARGO_HOME%\bin
- Try checking the installation again with
cargo --version.
If you have any issues installing, open a ticket with the error.
WCHLink-E (Only work with WCHLink-E, no WCHLink). Buy in Aliexpress
cargo install --git https://github.com/ch32-rs/wlink
or download a binary from the Nightly Release page.
Note On Linux, you should install libudev and libusb development lib first. Like
sudo apt install libudev-dev libusb-1.0-0-devon Ubuntu.
