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

crates.io Released API docs


  • 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:
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.

BTW, it could be built and flashed into STM32C8T6 (Blue-Pill) using Visual Studio Code. All required extensions are listed here.
