7 Segment Display Support

[GreihMurray]

Given:
A Seven Segment Display is connected to the Raspberry Pi.

When:
Data is sent to the display.

Then:
The display shows the appropriate numeric or character value based on the input.

Component Functionality:
This component will allow the Pi4Micronaut project to display numbers and characters on a single-digit seven-segment display for various monitoring and control purposes.

Developer Notes:

1. Draw the circuit setup for hardware connections: Show how the seven-segment display connects to GPIO pins on the Raspberry Pi.
2. Develop functionality to control the segments: Create a SevenSegmentDisplayHelper.java class that allows setting individual segments or numbers.
3. Implement methods to display numbers and characters: Support numbers (0-9) and some characters.
4. Configure GPIO pins appropriately: Ensure compatibility with different seven-segment displays (e.g., common cathode or common anode).
5. Create an example controller in componets folder to clearly demonstate the working of helper class.
6. Create a YAML configuration file for display settings: Add fields like name, address, commonType, provider.
7. Provide code comments for each function to develop documentation.

Acceptance Criteria:

• Functionality to control the seven-segment display: Should support showing numbers and characters.
• Component defined in YAML file with:
  • name
  • bus
  • device
• Schematic diagram accurately depicts the wiring for the seven-segment display.
• Controller Implementation in components folder
• Code comments provided for each functionality for documentation purposes.

This issue is for documenting the seven segment display #248

and Implementing Code for 7 Segment Display Integration, which includes writing and testing the necessary code to control the display.

Below are the @GreihMurray comments

Includes the need for a circuit, breadboard diagram, and functioning code to integrate the component with Micronaut

7 Segment display is an I2C device, may be able to leverage included CrowPi library to expedite the process
