I want to send data by Virtual Terminal (in Proteus ) and print it on LCD . I just need to type something in the virtual terminal and it should be displayed on the LCD. I'm using keil uvision,stm32f103c6, usart and lcd. I'm stuck at lcd programming

#include "stm32f10x.h"
#include <stdio.h>

#define RS 0x0020;
#define EN 0x0080;

void USART2_write(int ch);
char USART2_read (void);
void delayMs (int delay);

void LCD_command (unsigned char command);
void LCD_data (char data);
void delayMs (int delay);

int main(void)
{
char ch;

//***GPIO PORT***
//the clock for the GPIOA and USART2
RCC->APB2ENR|=0X0C;
RCC->APB2ENR|=0x0004; //0000 0100..Enable Clock for GPIOA
RCC->APB1ENR|=0x20000; //0010 0000 0000 0000 0000..Enable Clock for USART2..PIN17

//Configure GPIOA2 as alternate function
//Configure GPIOA2(Tx) as push-pull output alternate function at low frequency (0b1010)
//Configure GPIOA4(Rx) as a floating input (0b0100) which is its default state

GPIOA->CRL = 0x00004A00; //1010

//Enable Tx,Rx and USART2..both in CR1 Register

USART2->CR1|=0X2000; //enable usart..pin13 of CR1.. 0010 0000 0000 0000
USART2->CR1|=0X000C; //enable tx and rx..pin3 and pin2 of cr1..1100

//Set Baudrate to 9600 @16Mhz
//BAUD RATE(36000000/(16*9600))
USART2->BRR = 0X0EA6;

//*******
while(1)
{
ch=USART2_read(); //READ char from Serial Comm
USART2_write(ch); //return the char
delayMs(50);

}
GPIOB->CRL = 0x33333333;
GPIOA->CRL = 0x30300000;
