This library is to communicate between Tiva C series(TM4C123GH6PM) board and TM1637 4 digit display using Keil uprocessor

The TM1637 has 4 pins (VCC, GND, CLK, DIO)

The code is created based on above pins if you want to use different pins in port A goto Markup: PinConfig

Create a new project in uKeil and add header and cpp files in Source Group which is under Target folder

• TM1637Init - to initialize the port and pins
• setBrightness - to change brightness
• clear - to clear the display
• showNumberDec - display decimal number
• _delay_ms - to create delay (millisecs)

To use different pins in Port A please change the hex values of DEN and DIR to the respective values, these are located in TM1637.cpp --> TM1637Init method
GpioA->DATA (0x04) to specific pin hex value ---> Data (DIO) GpioA->DATA (0x08) to specific pin hex value ---> Clock (CLK)

Hex values for different pins

Some of the code was inspired by avishorp TM1637 for arduino code
