Hi tuxduino,
Yes! I am very sure! Actually everything works (send to serial via Serial.print, send to an LCD following the same logic) except sending to that 7-segment module.
I am pretty sure that the answer is somewhat related to tm1637.display(0,inputString[0]); and how it is created in the first place.
Here is a sketch created by the makers of the module. Look at the end of the sketch how tm1637.display (0,ListDisp[0]); is used in that case.
It refers to int8_t ListDisp[4]; from the beginning.
What would be the difference between int8_t ListDisp[4]; and something like String ListDisp[4]; or char ListDisp[4]?
Thank you for looking into this!
