TM1637 support

[bamboo-master]

I would like to use a 7 segment display on tm1637 in my sketch, there is already a library for stm8s and SDCC https://github.com/indigo6alpha/stm8s-tm1637 ,but I can't figure out how to use it in the arduino ide (sduino). Or how to safely connect such a display without libraries.

In general, put the source files into your project directory, and put #include "whatever.h" in your sketch

Oh no, I think it just won't work, it's not under arduino. I tried of course, added #include and got errors:

I actually do not insist on using this library, you need any way to achieve the connection of this display.

https://github.com/bitbank2/tm1637/tree/master/Arduino - works great!

It Shows error

It Shows error

You have an error in code - multiple definitions of _dummy_variable

[Sidbadode]

I used the same given code

include "tm1637.h"

// // Larry's TM1637 Library Demo // Displays counter from 0000 to 9999 with flashing colon // void setup() { // put your setup code here, to run once: tm1637Init(8, 9); // clock, data pins tm1637SetBrightness(4); }

void loop() { int i; char szTemp[8];

// put your main code here, to run repeatedly: for (i=0; i<9999; i++) { if (i & 1) sprintf(szTemp, "%02d:%02d", i/100, i% 100); else sprintf(szTemp, "%02d %02d", i/100, i % 100); tm1637ShowDigits(szTemp); delay(500); } }

[Sidbadode]

if i only use the library then also shows the same error

[bamboo-master]

I remember that it was necessary to rename some file so that all this would work in the arduino ide. Keep the working version, you need to unpack it to the folder %SYSTEMDRIVE%\Users\%username%\Documents\Arduino\libraries tm1637.zip

Thank you so much yes it works .
