# Presto Hub
This repository showcases a simple MicroPython project that displays dynamic information on a [Pimoroni Presto](https://shop.pimoroni.com/products/presto?variant=54894104052091) board (or a similarly configured Pico system).
It renders:
1. Date and Time
2. Weather (from configurable API)
3. Time-of-Use (TOU) Electrical Cost
4. Stock Quotes
5. Crypto Prices
6. A Small Dynamic “Artwork”
All settings (Wi-Fi credentials, APIs, and time-of-use pricing details) are managed through **config.json**.
---
## Files
- **LICENSE**
MIT license for this repository.
- **README.md**
You are here!
- **cherry-hq.af**
An Alright Fonts (.af) font used for fancy text.
_(Optionally used in your Presto project if you need a decorative font.)_
- **config.json**
Contains all the user-configurable settings:
- **wifi**: Enable/disable Wi-Fi, plus SSID and password.
- **weather**: Enable, plus city and API endpoints (defaults to `wttr.in`).
- **stocks**: Enable, plus list of stock tickers and API key (defaults to Alpha Vantage).
- **crypto**: Enable, plus list of crypto tickers and API URL (defaults to CoinGecko).
- **tou_d_prime**: Time-of-use scheduling details for electricity cost.
- **main_loop**: `update_interval` in seconds (the pause between each refresh).
- **main.py**
The main MicroPython script that:
1. Loads **config.json**
2. Connects to Wi-Fi if enabled
3. Fetches weather, stock, and crypto data periodically
4. Determines time-of-use cost rates
5. Draws everything to the Presto display
6. Updates every `update_interval` seconds
---
## Getting Started
1. **Copy Files**
Place `main.py`, `config.json`, and the optional `cherry-hq.af` font onto the Presto’s filesystem.
For example, if you’re using Thonny, drag-and-drop or open them in the “Raspberry Pi Pico” device and save them there.
2. **Set Up config.json**
- **Wi-Fi**:
```json
"wifi": {
"enable": true,
"ssid": "YourNetworkSSID",
"password": "YourNetworkPass"
}
```
Set `enable` to `true` or `false` depending on whether you want to connect.
- **Weather**:
```json
"weather": {
"enable": true,
"city": "London",
"api_url": "http://wttr.in?format=j1"
}
```
You can specify your city or region.
- **Stocks**:
```json
"stocks": {
"enable": true,
"tickers": ["AAPL", "GOOG"],
"api_key": "YourAlphaVantageKey"
}
```
- **Crypto**:
```json
"crypto": {
"enable": true,
"tickers": ["bitcoin", "ethereum"],
"api_url": "https://api.coingecko.com/api/v3/simple/price?vs_currencies=usd"
}
```
- **Time-of-Use**:
```json
"tou_d_prime": {
"summer_months": [6, 7, 8, 9],
"weekend_days": [5, 6],
...
}
```
Adjust “summer” and “winter” schedules to reflect your local electricity rates.
- **Main Loop**:
```json
"main_loop": {
"update_interval": 10
}
```
The number of seconds to wait between each screen refresh.
3. **Install Dependencies**
This script expects the “Presto” ecosystem, including modules like `requests` (from the MicroPython networking bundle) and `pico_graphics`.
Make sure you’re using the custom MicroPython build for Presto or have these modules available.
4. **Run main.py**
- After resetting or pressing “Play” in Thonny, the script should load your config and begin displaying data.
- If Wi-Fi is enabled and credentials are valid, the script will attempt to connect and then fetch real data.
---
## Troubleshooting
- **Wi-Fi Failing**: Double-check your SSID and password in `config.json`.
- **No Weather/Stocks**: Possibly missing or invalid API keys. Also make sure the device is indeed connected to Wi-Fi.
- **Unresponsive Display**: Ensure you’ve flashed a Presto-compatible MicroPython firmware. Check that your cable/pins are correct.
- **Performance**: The `update_interval` in `config.json` can be raised if you need fewer API calls or to lighten the CPU load.
