Display doesn't work
Hello, I have a project with 3x 7segment displays. If I use the library TM1637 (TM1637.h) , all of displays are working perfectly. But there aren't enough functions for my project, so i tried to use this library form Avishorp (TM1637Display.h) and two of the displays working good and one doesn't work. It shows only incorrect value or nothing. CLK and DIO is connected to pins 2, 3. If I try different pins, it's the same. If I try to change to the previous library, suddenly it's working! I don't expect any problem in my program, because if I change displays in program (each other), still the same situation, when this one display doesn't work. My idea is that this problematic display is some different (version, HW) and noncompatibile with this library, but they seems identic to me. Is it possible? Or any idea for fix it?
Thanks for help a lot :-)
Fixed. I went from Arduino nano (clone) to NodeMCU ESP 8266 with the same code and everything works now. So, I think that the arduino couldn't do all of my instructions. NodeMCU has more performance and there is no problem now.
