Running Demo Code

To run the demo code, perform the following on VisionFive 2 Debian:

Locate to the directory where the code, led.py, exists:
1. Source into the Python3 Virtual Environment:
```
source ./myvenv/bin/activate
```
2. Execute the following command to install dependency:
```
python3 -m pip install pillow
```
3. Execute the following command to get the directory where VisionFive.gpio exists:
```
python3 -m pip show VisionFive.gpio
```
  Result:
```
Location: /home/user/myvenv/lib/python3.11/site-packages
```
  Note:
  The actual output depends on how the application is installed.
4. Execute the following to enter the directory, for example, /home/user/myvenv/lib/python3.11/site-packages as indicated in the previous step output:
```
cd /home/user/myvenv/lib/python3.11/site-packages
```
5. Execute the following command to enter the sample-code directory:
```
cd ./VisionFive/sample-code/
```
Under the sample-code directory, execute the following command:
```
sudo python led.py
```
Alternatively, you can execute the following command:
```
sudo python3 led.py
```
Enter the period (unit: second) to configure the time when the LED is turning off or on.
For example, enter 2. The following is the example output:
```
[riscv@fedora-starfive sample-code]$ sudo python3 led.py
Enter delay(seconds): 2
```
Result:
The LED turns on and off in 2 second intervals.
(Optional) Exit the Python3 Virtual Environment.
```
deactivate
```
