I want to create a traffic light simulation project using the TM$4$C$123$ microcontroller. I would like to control the lights using the GPIO pins connected to the LEDs on the circuit. Additionally, I want to display the remaining time on an OLED and adjust the brightness of the lights using a potentiometer. Finally, I would like to implement start and stop controls using the UART system. Use Keil uVision $5$ to program in C language. I need the whole C code. Not a simplified version. I need a working code as whole.
