A MicroPython library for controlling TM1637 quad 7-segment LED display modules with easy-to-use methods.
MicroPython TM1637 is a driver library for controlling TM1637-based quad 7-segment LED display modules using MicroPython. It provides methods to display numbers, text, hexadecimal values, temperatures, and scrolling text, simplifying integration into embedded projects. The library handles low-level communication with the TM1637 chip, allowing developers to focus on application logic.
Embedded developers and hobbyists using MicroPython on boards like ESP8266, Raspberry Pi Pico, or TinyPICO who need to interface with TM1637 LED displays for numeric or alphanumeric output.
It offers a clean, well-documented API with built-in support for common display tasks, reducing the need to manually manage segment encoding. As an open-source library, it is lightweight, easy to install via mip, and compatible with various hardware modules.
MicroPython driver for TM1637 quad 7-segment LED modules
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
The write() method allows low-level segment manipulation, enabling custom patterns and symbols beyond the predefined font, as demonstrated in the examples for raw byte writing.
Includes built-in methods for numbers, text, hex, temperature, and scrolling, reducing boilerplate code for common display tasks like showing '12:59' or '-123'.
Installation via mip or manual file copy is straightforward, and the README provides clear pin connection guides for boards like Raspberry Pi Pico and ESP8266.
The README includes a detailed 7-segment font map with binary, hex, and decimal values, aiding in customization and troubleshooting for advanced users.
Only compatible with TM1637-based displays, making it unsuitable for projects using other LED drivers like MAX7219 or graphical displays, as admitted by its niche focus.
Relies on software bit-banging for CLK and DIO pins, which can be slower and more CPU-intensive than hardware-driven interfaces, potentially affecting real-time applications.
The predefined font is minimal and lacks support for many symbols or international characters, requiring manual encoding via write() for special cases, which adds complexity.
