Preparing Software

Make sure the following procedures are performed:

Note: The python project, VisionFive.gpio, is applicable for VisionFive, VisionFive 2 and JH7110 EVB.

Flash Debian OS into a Micro-SD card as described in the Flashing Fedora OS to a Micro-SD Card section in the VisionFive 2 Single Board Computer Quick Start Guide.
Log into the Debian and make sure VisionFive 2 is connected to the Internet. For detailed instructions, refer to the Using SSH over Ethernet or Using a USB to Serial Converter section in the VisionFive 2 Single Board Computer Quick Start Guide.
Extend the partition on Debian as described in Extend Partition in the VisionFive 2 Single Board Computer Quick Start Guide.
Execute the following command to install PIP on Debian:
```
apt-get install python3-pip
```

Execute the pip command on VisionFive 2 Debian to install the VisionFive.gpio package:

Note: Due to the fact that pypi.org official website does not yet support uploading whl installation packages for the RISC-V platform, so it cannot directly execute pip install VisionFive.gpio command to install online.

Please follow the steps below to install the VisionFive.gpio package.

Execute the following command to install dependent package:

apt install libxml2-dev libxslt-dev
python3 -m pip install requests wget bs4

Execute the following command to run the installation script Install_VisionFive_gpio.py:

python3 Install_VisionFive_gpio.py

The installation script codes are as follows:
