## Repository Structure

This repository is organized into several main directories, each serving a specific purpose in the PicoCalc project:

### `Bin/`

Prebuilt binary files and firmware images.

* Contains ready-to-use firmware (e.g. .uf2, .bin, .hex)

* Useful for users who want to flash the device directly without building from source

* May include release builds and test/debug versions

## `Code/`

Source code for firmware and software components.

* Main application logic for PicoCalc

* Hardware drivers and low-level interfaces

* Build configurations and toolchain setup

* May include experimental features and development branches

This is the directory you should look at if you want to:

* Modify functionality

* Add features

* Rebuild firmware


## `wiki/`

Project documentation and additional resources.

* Usage guides

* Development notes

* Design explanations

* Troubleshooting and FAQs

This section is intended to complement the README with more detailed or evolving documentation.
