## **Installations**

1. **OS install:**

   - Install Raspberry Pi OS Lite (64-bit) on your Raspberry Pi 


   

2. **Enable SPI & I2C:**

   - Open a terminal on your Raspberry Pi.

   - Run `sudo raspi-config`

   - Navigate to Interfacing Options -> SPI -> Enable.

   - Navigate to Interfacing Options -> I2C -> Enable.

3. **Python libraries:**

   - sudo apt-get update

   - sudo apt-get install python3-pip -y

   - sudo apt-get install python3-pil -y

   - sudo apt install python3-spidev -y

   - sudo apt-get install python3-numpy -y

   - sudo apt install python3-matplotlib -y

   


# Wiring and Setup

1. **Connect 2.13inch e-Ink HAT to Raspberry Pi:**

   - Connect the 2.13inch e-Ink HAT to your Raspberry Pi. 


   - Connect the UPS Hat for continuous power supply. This will allow you to move the project anywhere without worrying about power interruptions.

2. Clone the repository:

   ```bash

   sudo apt install git -y

   git clone https://github.com/frogCaller/e-ink-ticker.git

   cd e-ink-ticker

  

# Usage

Run the script:

   - `python3 ticker.py`

# How It Works

  - The script fetches cryptocurrency prices and 7-day historical data from the CoinGecko API every 5 minutes.

  - The data is displayed on the e-Ink screen, refreshing every 20 seconds.

  - The y-axis scale of the graphs is adjusted based on the lowest and highest prices of the week.

# Troubleshooting

Common Issues:

   - Ensure SPI & I2C are enabled in the Raspberry Pi configuration.

   - Check all connections if the screen does not display anything.

   - Verify all required packages are installed correctly.
