# `TM1637`

> A lightweight platform-agnostic driver to a LED-display powered by the TM1637 chip

[![crates.io](https://img.shields.io/crates/v/tm1637.svg)](https://crates.io/crates/tm1637)

[![Released API docs](https://docs.rs/tm1637/badge.svg)](https://docs.rs/tm1637)

## Features

- Formatting number as HEX-digits

- Controlling each particular segment using a bitmask

- Brightness control

- Low ROM usage, e.g. the working example features using the following config take **488**\* additional bytes:

```toml

[profile.release]

codegen-units = 1

debug = true

lto = true

opt-level = 'z'

```

_\* 580 bytes in case if the real HAL delay is used._

## Working Example

A simple example using a 4-digit LED-display is located [here](examples/main.rs).

BTW, it could be built and flashed into STM32C8T6 (Blue-Pill) using Visual Studio Code.

All required extensions are listed [here](.vscode/extensions.json).
