// AUTHOR: Rob Tillaart

// DATE: 2019-10-28
|
|
// VERSION: 0.4.0
|
|
// PURPOSE: TM1637 library for Arduino
|
|
// URL: https://github.com/RobTillaart/TM1637_RT
|
|
|
|
// NOTE:
|
|
// on the inexpensive TM1637 boards @wfdudley has used, keyScan
|
|
// works if you add a 1000 ohm pull-up resistor from DIO to 3.3v
|
|
// This reduces the rise time of the DIO signal when reading the key info.
|
|
// If one only uses the pull-up inside the microcontroller,
|
|
// the rise time is too long for the data to be read reliably.
|
|
|
|
// tested on 6 digit display
|
|
// tested on 4 digit (clock) display esp. displayTime()
