Raspberry-tm1637

TM1637 Driver for RaspberryPi.
I based it on this.

Changes from the original

• Applied to WiringPi.
• Added display of ascii characters.
• Added text scroll display function.
• Added text animation display function.

Software requirement

WiringPi Library
This project uses the wiringPiSetupGpio() function to initialize GPIO.
If you use it on a board other than the RPI board, you may need to change the GPIO number.
As far as I know, there are these libraries.

• WiringPi for OrangePi
• WiringPi for BananaPi
• WiringPi for NanoPi
• WiringPi for Pine-64

Hardware requirement

TM1637 8 segment 0.36INCH Digital Display Tube 4 digit LED module.
There are several products with different segments.

• Product 1
  8 segments with dots + 8 segments with dots + 8 segments with dots + 8 segments with dots
• Product 2
  7 segments + 8 segments with colon + 7 segments + 7 segments

Build

git clone https://github.com/nopnop2002/Raspberry-tm1637
cd Raspberry-tm1637
cc -o tm1637 main.c tm1637.c -lwiringPi -lpthread

Wiring

TM1637		RPi
CLK	--	GPIO3	(*1)
DIO	--	GPIO2	(*1)
GND	--	GND
VCC	--	3.3V

(*1)
The TM1637's interface is similar to I2C, but it is not I2C.
Therefore, you can change it to any pin using arguments.

How to use

$ ./tm1637 --help
./tm1637: invalid option -- '-'
usage: tm1637  [-c CLK] [-d DIO] [-t TEXT]

optional arguments:
  -c CLK    CLK GPIO
  -d DIO    DIO GPIO
  -t TEXT   Display Text

Start Auto Demo using default GPIO

./tm1637

Start Auto Demo using non-default GPIO

Example of CLK=GPIO14/DIO=GPIO15.

./tm1637 -c 14 -d 15

Display any text using default GPIO

./tm1637 -t "12345 67890"

Display any text using non-default GPIO

Example of CLK=GPIO14/DIO=GPIO15.

./tm1637 -c 14 -d 15 -t "12345 67890"
