  Arduino library for TM1637 (LED Driver)

At first I thought they were I2c, but they are not. I found some information that might be useful in the links below. I have 2 speculations (not answers) on how to use multiples of this display. 1. use TCA9548A I2C Multiplexer, use I2C to the tell the TCA9548A to select a port. use "TM1637Display library" to access a display https://github.com/avishorp/TM1637 2. use "1M1637Display library" to access a display, but pick different pairs of pins. https://github.com/avishorp/TM1637 ---------------------------------------------------------------------------------------- A comparison of the TM1637 protocol with I2C protocol https://green-possum-today.blogspot.com/2018/10/a-comparison-of-tm1637-protocol-with.html Here is an example (uses library listed above) TM1637 4-digit 7-segment display Arduino example code https://www.makerguides.com/tm1637-arduino-tutorial/ TCA9548A I2C Multiplexer https://www.adafruit.com/product/2717

  Arduino library for using a 4 digit seven segment display with TM1636 or TM1637 driver IC

My previous library was https://github.com/bremme/arduino-tm1637. It works fine otherwise on up to 2 displays sharing a pin...
