# python-periphery-tm1637
[](https://www.codefactor.io/repository/github/magnetrwn/python-periphery-tm1637)
This module contains methods to drive the TM1637 display module as well as clock, scrolling ASCII text and system information functionality. Attaching this to a SBC can give useful insight on the system status or just keep time.

# Software requiments
python-periphery library.
```
sudo apt update
sudo apt install git python3-pip python3-setuptools
git clone https://github.com/vsergeev/python-periphery.git
cd python-periphery/
python3 -m pip install python-periphery
```
# Why python-periphery
python-periphery is a highly compatible library.
Available for most Pi boards.
# Wiring
|LED Module|Raspberry Pi||
|:-:|:-:|:-:|
|CLK|Pin#5|(*1)|
|DIO|Pin#3|(*1)|
|GND|GND||
|5V|3V3|(*2)|
(*1)
You can use any GPIO with startup arguments.
(*2)
RPi reads data from DIO, so it must be 3V3.
# Setup
```
cd $HOME
git clone https://github.com/nopnop2002/python-periphery-tm1637
cd python-periphery-tm1637/
python3 tm1637.py
```
If you use this module on something other than Raspberry Pi, you will need to change the GPIO.
```
$ python3 tm1637.py --help
usage: tm1637.py [-h] [--clk CLK] [--dio DIO] [--text TEXT]
optional arguments:
-h, --help show this help message and exit
--clk CLK CLK GPIO
--dio DIO DIO GPIO
--text TEXT
```
If you use Pin#3 and Pin#5, it will be as follows.
||CLK(Pin#5)|DIO(Pn#3)||
|:-:|:-:|:-:|:-:|
|Raspberry Pi|3|2|Default|
|Orange Pi Allwinner H2+|11|12||
|Orange Pi Allwinner H3|11|12||
|Orange Pi Allwinner H5|11|12||
|Orange Pi Allwinner A64|226|227||
|Orange Pi 3|121|122||
|Orange Pi Lite2|229|230||
|Orange Pi OnePlus|229|230||
|Orange Pi RK3399|44|43||
|Orange Pi 4|65|64||
|Nano Pi Allwinner H3|11|12||
|Nano Pi Allwinner H5|11|12||
Other default values are set as follows:
```
_DEF_TM1637_BRIGHT = 0xA # Default brightness from 0x0 to 0xF
_DEF_TM1637_ANIM_DELAY = 0.2 # Default animation delay in seconds
```
If you want to display the CPU temperature, you need to change the following depending on the board.
```
show_on_high_cpu_thermal(tm, 50, "/sys/devices/virtual/thermal/thermal_zone0/temp")
# Please change your cpu sensor path if different
```
# Start Auto Demo
```

```
When specifying GPIO.
```
python3 tm1637.py --clk=11 --dio=12
```
Privilege elevation might be required.
```
sudo -E python3 tm1637.py
```
# Display text
```
python3 tm1637.py --text="any_text"
```
When specifying GPIO.
```
python3 tm1637.py --text="any_text" --clk=11 --dio=12
```
Privilege elevation might be required.
```
sudo -E python3 tm1637.py --text="any_text"
```
