I need to complete this C code and I need it to run on UART For “Texas Instruments TM4C123G Development Board EK-TM4C123GXL”

“For my microprocessor that receives a string from UART”
“Visual Studio Code”
For “Texas Instruments TM4C123G Development Board EK-TM4C123GXL”
I need to complete this C code and  I need it to run on UART.
This the C code and I need to complete it:
/*

* UART TX

*

*/
#include

#include
void configure_uart() {

   // Add the configuration steps necessary to enable U0TX at

   // 115200bps

   // 8 data bits

   // No parity

   // 1 Stop bit

   // See datasheet Section 14.4, pg 902-903 for Init Procedure

   // See datasheet Section 14.3.2, pg 896 for the Baudrate (115200) calculation

   // Also in Valvano 8.3.2 UART Device Driver, pg 319 in 4th ed

   // or 11.2.2. TM4C UART Details

   // (http://users.ece.utexas.edu/~valvano/Volume1/E-Book/C11_SerialInterface.htm)

   //

   // NOTE: Our System (Bus) Clock is 16MHz (the reset default)

   //

   // Registers you will need to configure:

   //   RCGCUART

   // RCGCGPIO

   // UARTCTL

   // UARTIBRD

   // UARTFBRD

   // UARTLCRH

   // GPIOPCTL

   // GPIOAFSEL

   // GPIODEN

}
void uartwrite(unsigned char data) {

   // Use UARTFR, datasheet pg 911, TXFF bit to make sure the TX FIFO is not full

   // then UARTDR, datasheet pg 906 to write this new character into the TX FIFO

}
void say_hello() {

   // Modify hello string constant to include your name

   char hello[] = “Hello class, from NAMErn”;
   while (true) {

       // Send one character of hello[] string at a time, repeating forever

       // The length of the hello[] string can be calculated as:

       //   sizeof(hello)

   }

}
int main() {

   configure_uart();
   say_hello();
   while (true)

       continue;

}
