Hi, you can try some like this...

#include "mbed.h"
#include "TextLCD.h"

Serial pc(USBTX, USBRX);
TextLCD lcd(PA_10, PB_3, PB_5, PB_4, PB_10, PA_8); // rs, e, d4-d7 
DigitalOut myled(LED1); 


int main()
{
    char str [32]; // small array
     
     lcd.cls();
     lcd.setAddress(0,0);
     lcd.printf("Hello World!\nSerial to LCD");
    
    while(1){
            pc.scanf("%s", str); //fill data to array from UART
            lcd.cls(); // clean display and return home position column 0 and row 0
            myled =! myled; //no blink no fun
            lcd.printf("%s", str); //put data from array to display
    }
}

You did not specify what display you have. I suppose it is 16 * 2 with parallel communication.
