This repo adds the support of CH32 MCU in Arduino IDE.
The file includes:
- Arduino_Core_CH32:Public library files.
- openocd:can directly use WCH-LINKE to download and debug wch chips.
- riscv-none-embed-gcc:A toolchain that supports WCH custom half word and byte compression instruction extensions and hardware stack push/pop functions.
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.
It will be a long-term support and maintenance project, unless we encounter force majeure factors.The current version supports the following development boards:
| Status | Boards name | Peripherals | Release | Notes |
|---|---|---|---|---|
| ✔️ | CH32V003F4P | ADC,DAC,USART,GPIO,EXTI,SysTick | 1.0.0 | SPI,I2C_Master since 1.0.2 |

Adopting toolchain and openocd under MRS, supporting HPE, custom byte and half-word compression extensions,"upload" via WCH_LINKE.
Most importantly, the version of Arduino IDE is 2.0+.
If you encounter an error during upload, please confirm that the version of your WCH-LINKE is consistent with the latest version under MRS. WCH-LINKE related information can refer to this link.
For Linux, after installing the support package for the first time, to ensure the normal upload function, please open the packages installation path of the Arduino IDE, run the script, and automatically configure the environment.
Usually, it can be operated as follows:
cd ~/.arduino15/packages/WCH/tools/beforeinstall/1.0.0
./start.shAfter authorization, it will copy or generate some necessary libraries and rules:
Copy Libs
[sudo] password for temperslee:
Register new Libs
copy rules
Reload rules
DONE
For MAC, please install the "libusb" library before starting to use it.
brew install libusbIf "libusb" related errors still occur when "uploading" firmware after installing the libusb library, please contact the MRS team for assistance through "[email protected]".
If you have any questions, you could contact me through the email "[email protected]". Or you could file an issue on GitHub.
