## 1 RTduino - Arduino Eco-compatibility Layer for RT-Thread
|
||
|
|
|
||
|
|
The ra6m3-hmi-board development board has been fully adapted to the [RTduino software package](https://github.com/RTduino/RTduino), which is an Arduino eco-compatibility layer for RT-Thread. Users can program this BSP in accordance with Arduino coding conventions and can utilize a wide range of libraries from the Arduino community, significantly enhancing the RT-Thread ecosystem. For more information, please refer to the [RTduino software package documentation](https://github.com/RTduino/RTduino).

|
### 1.1 Enabling the Arduino Eco-compatibility Layer for this BSP
|
||
|
|
|
||
|
|
In the Env tool, enter the "menuconfig" command, or in the RT-Thread Studio IDE, select "RT-Thread Settings":
|
||
|
|
|
||
|
|
```Kconfig
|
||
|
|
Hardware Drivers Config --->
|
||
|
|
Onboard Peripheral Drivers --->
|
||
|
|
[*] Compatible with Arduino Ecosystem (RTduino)
|
||
|
|
```
