TM1638 LED&KEY keyboard and LED indication module on the TM1638 driver for information input/output. The board contains 8 seven-segment indicators, 8 LEDs and 8 buttons. It uses its own serial interface for control.
The TM1638 microcircuit controls the indicators and detects button presses. It receives from the microcontroller and transmits data over a unique serial interface - half-duplex SPI. The difference from SPI is that two transmit and receive lines are combined into one line.
