USART

Hi I'm having issue getting the data send from the usart1; I initialised properly, but the problem is not the rightdata is display on my PC terminal; I'm using stm32f407VG

#include "stm32f4xx.h"
#include <stdio.h>

        GPIO_InitTypeDef GPIO_InitStruct;
        RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOD, ENABLE);
        GPIO_InitStruct.GPIO_Pin = GPIO_Pin_15 | GPIO_Pin_14 | GPIO_Pin_13 | GPIO_Pin_12; // we want to configure all LED GPIO pins
        GPIO_InitStruct.GPIO_Mode = GPIO_Mode_OUT;              // we want the pins to be an output
        GPIO_InitStruct.GPIO_Speed = GPIO_Speed_2MHz;   // this sets the GPIO modules clock speed
        GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;     // this sets the pin type to push / pull (as opposed to open drain)
        GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_NOPULL;   // this sets the pullup / pulldown resistors to be inactive
        GPIO_Init(GPIOD, &GPIO_InitStruct);                         // this finally passes all the values to the GPIO_Init function which takes care of setting the corresponding bits.



        RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE);
        GPIO_InitStruct.GPIO_Pin = GPIO_Pin_0;            // we want to configure PA0
        GPIO_InitStruct.GPIO_Mode = GPIO_Mode_IN;         // we want it to be an input

        GPIO_InitStruct.GPIO_OType = GPIO_OType_PP;   // this sets the pin type to push / pull (as opposed to open drain)
        GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_DOWN;   // this enables the pulldown resistor --> we want to detect a high level
        GPIO_Init(GPIOA, &GPIO_InitStruct);                   // this passes the configuration to the Init function which takes care of the low level stuff
