4 Digit Two Wire Display With Arduino
Intro: 4 Digit Two Wire Display With Arduino
I was working on a project where i needed a 4 digit display but when I went to connect it to the Arduino all I found were articles about having to wire up 12 plus pins. Then I found this Suli library which makes it so simple a dummy like me can wire it up with two pins (digitial 2 and digital 3).
Stuff needed:
Grove TM1637 4 Digit display
Suli library
Four_Digiit_Display_Suli library
STEP 1: Connect Display to Arduino
If you have an Arduino with an I2C two wire plug then it's a no brainer.
I only had an Uno so connect display vcc to 5v, gnd to gnd, DIO to Arduino digital pin 2, and CLK to Arduio digital pin 3.
Done.
STEP 2: Download Libraries
Get Suli library here: https://github.com/Seeed-Studio/Four_Digit_Display_Suli
Now I did have a problem running the demo until I copied the cpp and header files from
here: https://github.com/Seeed-Studio/Suli/tree/master/Suli_Arduino (Guess they had updates).
Get Four_Digit_Display here: https://github.com/Seeed-Studio/Four_Digit_Display_Suli
Hope you know how to install libraries.
Run the Four_Digit_Display demo in the Examples file.
Rock on!

It will work with any tm1637 based display.

Can't seem to compile it - any chance you could provide more detail for step 2?

Sorry I just saw your comment today - don't know where I have been. But sadly I don't have this stuff anymore or even the code. Hope you got it worked out.
