tm1637-rpi5-gpiod 2.0.0

TM1637 4-digit display driver for Raspberry Pi 5 using gpiod

TM1637 Display Library for Raspberry Pi 5 (gpiod-based)

This is a modified version of the raspberrypi-tm1637 library, adapted to work on Raspberry Pi 5 using the gpiod backend.

🚀 Why this version?

The Raspberry Pi 5 uses a new GPIO controller that is not compatible with RPi.GPIO, which the original TM1637 library depends on.

This version replaces RPi.GPIO with gpiod (libgpiod), the officially supported GPIO access method in Raspberry Pi OS (Bookworm and newer).

Now, version 2.0.0 of tm1637-rpi5-gpiod, auto-detects whether libgpiod v1 or v2 is present and uses the appropriate backend:

• libgpiod v1 (legacy API): per-line requests
• libgpiod v2 (new API): LineSettings + request_lines() + LineRequest.set_value()

📥 Installation

1. Install required dependencies:

   sudo apt update
   sudo apt install python3-libgpiod gpiod
   

2. Install the library via pip:

   pip install tm1637-rpi5-gpiod
   

   Or clone manually:

   git clone https://github.com/villeparamio/tm1637-rpi5-gpiod.git
   cd tm1637-rpi5-gpiod
   pip install .
   

🧪 Example usage

import tm1637
from time import sleep

CLK = 24  # GPIO24 (physical pin 18)
DIO = 23  # GPIO23 (physical pin 16)

display = tm1637.TM1637(clk=CLK, dio=DIO)
display.brightness(7)

while True:
    display.show("TEST")
    sleep(2)
    display.numbers(12, 34)
    sleep(2)

Make sure your user is in the gpio group to access /dev/gpiochip* without root.
If needed: sudo usermod -aG gpio $USER && sudo reboot
