“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;
}
