Running Demo Codes

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

Locate to the directory where the test code, pud_test.py, exists:
1. Execute the following command to get the directory where VisionFive.gpio exists:
```
pip show VisionFive.gpio
```
  Result:
```
Location: /usr/local/lib64/python3.9/site-packages
```
  Note:
  The actual output depends on how the application is installed.
2. Execute the following to enter the directory, for example, /usr/local/lib64/python3.9/site-packages as indicated in the previous step output:
```
cd /usr/local/lib64/python3.9/site-packages
```
3. Execute the following command to enter the sample-code directory:
```
cd ./VisionFive/sample-code/
```

Under the sample-code directory, execute the following command to execute the demo code:

sudo python pud_test.py

Alternatively, you can execute the following command:

sudo python3 pud_test.py

Result:

The terminal displays as follows:

# python3 pud_test.py
*----------------------Start testing------------------------------*

Step 1: set input to direction of GPIO pin 31.

Step 2: the default input level is HIGH.

Step 3.1: set PUD_DOWN to input direction of GPIO pin 31.

Step 3.2: the input level with pull_down enabled is LOW.

Step 4.1: set PUD_UP to input direction of GPIO pin 31.

Step 4.2: the input level with pull_up enabled is HIGH.
