Frogweather - a Frog-Themed Weather Station

What is Frogweather?

Frogweather is a weather app written in Python. It generates images that show both the current time and weather information, specifically the temperature and precipitation probability within the next nine hours. The background image shows a frog-themed visualization of the current weather.

Since this app is meant to provide weather station images that are displayed on a 64x128 LED matrix, the images are of size 64x128. If you need other sizes, you can resize the images or replace the background images by your own images. The background images are located in the images folder.

How to use Frogweather?

First, run the example program:

1. Install the Python package:

   pip install frogweather

2. Request a Dark Sky API key. The key comes for free and allows you to access the Dark Sky weather service 1000 times a day without charge. Frogweather is designed not to exceed this limit.

3. Paste your key into the file darkskykey.yaml.

4. Find out the geographical coordinates of your location, for example via GPS Coordinates.

5. Paste your coordinates into the file location.yaml.

6. Run the example program:

   python frogweather.py

   This command will open a window that displays the weather station image. It will also continuously update the image.

Now you can use the frogweather module in your own Python program. The following Python code snippet shows how to do it:

# Import the module.
import frogweather

# Read the configuration files.
frogweather.init()

# Continuously check for new weather station images.
while True:
    # Check if a new weather station image is available.
    if frogweather.update():
        # Access the updated image.
        image = frogweather.get_image()

How does Frogweather work?

In order to generate an image, the frogweather Python module executes the following steps:

1. It retrieves the current time from the operating system.
2. It downloads the current local weather information, i.e. temperature and precipitation probability, from the Dark Sky weather server.
3. It renders the weather station image.
