Uart STM32F4 FTDI232

Hi, I am just a beginner with Keil and STM32, so I apologize for stupid questions. I would like to read the conversion of the ADC1 (using the Analog Wathcdog timer) present on the STM32F4 discovery board and send it through USART1 to the PC (and visualize that). I am using FTDI232 USB UART converter, and I have attached the pins as follows (FTDI232-STM32F4):

RX-PA10
TX-PA9
GND-GND

My code is the following:

#include "stm32f4_discovery.h"
#include "stdio.h"

__IO uint16_t ADC1ConvertedValue = 0;
__IO uint16_t ADC1ConvertedVoltage = 0;
USART_InitTypeDef USART_InitStructure;
USART_ClockInitTypeDef USART_ClockInitStructure;
GPIO_InitTypeDef GPIO_InitStructure;
GPIO_InitTypeDef GPIO_InitStructure2;
ADC_InitTypeDef ADC_InitStructure;
ADC_CommonInitTypeDef ADC_CommonInitStructure;

int main(){ Delay(0xFFFFFF); GPIOInitialize(); ADC_Configuration(); UART_Initialize(); ADC_SoftwareStartConv(ADC1); //GPIO_SetBits(GPIOC, GPIO_Pin_2); while(1);
}

void GPIOInitialize(void)
{ RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOA, ENABLE); //Enable clock for GPIOB

/* USART1 Tx on PA9 | Rx on PA10 */ GPIO_InitStructure.GPIO_Pin = GPIO_Pin_9 | GPIO_Pin_10; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_AF; GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz; GPIO_InitStructure.GPIO_OType = GPIO_OType_PP; GPIO_InitStructure.GPIO_PuPd = GPIO_PuPd_UP;

GPIO_Init(GPIOA, &GPIO_InitStructure); GPIO_PinAFConfig(GPIOA, GPIO_PinSource9, GPIO_AF_USART1);//Connect PA9 to USART1_Tx GPIO_PinAFConfig(GPIOA, GPIO_PinSource10, GPIO_AF_USART1);//Connect PA10 to USART1_Rx
}

USART_Init(USART1, &USART_InitStructure); // USART configuration USART_Cmd(USART1, ENABLE); // Enable USART

USART_ClockStructInit(&USART_ClockInitStructure); USART_ClockInit(USART1, &USART_ClockInitStructure);

NVIC_InitTypeDef NVIC_InitStruct; NVIC_InitStruct.NVIC_IRQChannel = USART1_IRQn; NVIC_InitStruct.NVIC_IRQChannelCmd = ENABLE; NVIC_InitStruct.NVIC_IRQChannelPreemptionPriority = 0xFF; NVIC_InitStruct.NVIC_IRQChannelSubPriority = 0xFF; NVIC_Init(&NVIC_InitStruct); //USART_ITConfig(USART1, USART_IT_TC, ENABLE);
}

void Delay(__IO uint32_t nCount)
{

while(nCount--) { }
} void ADC_Configuration(void)
{

GPIO_InitStructure2.GPIO_Pin = GPIO_Pin_2; GPIO_InitStructure2.GPIO_Mode = GPIO_Mode_IN; GPIO_InitStructure2.GPIO_PuPd = GPIO_PuPd_NOPULL ; GPIO_Init(GPIOC, &GPIO_InitStructure2); GPIO_Init(GPIOD, &GPIO_InitStructure);

ADC_Cmd(ADC1 , ENABLE);

}

void ADC_IRQHandler(void) { Delay(0xFFFFFF); ADC_ClearFlag(ADC1,ADC_FLAG_AWD); ADC_ClearITPendingBit(ADC1, ADC_IT_AWD); GPIO_ToggleBits(GPIOD, GPIO_Pin_12|GPIO_Pin_13|GPIO_Pin_14|GPIO_Pin_15); ADC1ConvertedValue=ADC_GetConversionValue(ADC1); USART_SendData(USART1,ADC1ConvertedValue); while(USART_GetFlagStatus(USART1, USART_FLAG_TC) == RESET); Delay(0xFFFFFF); GPIO_ToggleBits(GPIOD, GPIO_Pin_12|GPIO_Pin_13); Delay(0xFFFFFF); }

I do the debugging and run the program (on Keil), it works, but I can't see any value in the windows UART#1,2,3...

Am I connecting it wrong? How can I visualize the data exchanged by the USART1? Which are the settings to do (Options for target) to use the specified hardware?
