# Arduino core support for CH32 EVT Boards
2+
3+
* [Introduction](https://github.com/openwch/arduino_core_ch32#Introduction)<br>
4+
* [How to use](https://github.com/openwch/arduino_core_ch32#How-to-use)<br>
5+
* [Supported boards](https://github.com/openwch/arduino_core_ch32#Supported-boards)<br>

* [Submit bugs](https://github.com/openwch/arduino_core_ch32#Submit-bugs)<br>
7+
8+
## Introduction
9+
10+
This repo adds the support of CH32 MCU in Arduino IDE.<br>
11+
12+
The file includes:
13+
* [Arduino_Core_CH32](https://github.com/openwch/arduino_core_ch32):Public library files.
14+
* [openocd](https://github.com/openwch/openocd_wch):can directly use WCH-LINKE to download and debug wch chips.
15+
* [riscv-none-embed-gcc](https://github.com/openwch/risc-none-embed-gcc):A toolchain that supports WCH custom half word and byte compression instruction extensions and hardware stack push/pop functions.
16+
17+
## How to use
18+
19+
You can add this software package directly on the IDE through the [Arduino Boards Manager](https://www.arduino.cc/en/guide/cores).
20+
21+
Add the following link in the "*Additional Boards Managers URLs*" field:
22+
23+
https://github.com/openwch/board_manager_files/raw/main/package_ch32v_index.json
24+
25+
Then you can search for "**wch**" through the "**board manager**", find the installation package, and install it.
26+
27+
## Supported boards
28+
29+
It will be a long-term support and maintenance project, unless we encounter force majeure factors.The current version supports the following development boards:
30+
31+
- [CH32V00x EVT Boards](#CH32V00x-EVT-Boards)
32+
- [CH32V20x EVT Boards](#CH32V20x-EVT-Boards)
33+
