#include <stddef.h>

#include "stm32f10x.h"

#include "STM32vldiscovery.h"

static __IO uint32_t TimingDelay;

void Delay(uint32_t nTime);

void TimingDelay_Decrement(void);

//-----------------------------------------------------------------------------

int main(void)

{

STM32vldiscovery_PBInit(BUTTON_USER, BUTTON_MODE_GPIO);

STM32vldiscovery_LEDInit(LED3);

STM32vldiscovery_LEDInit(LED4);

STM32vldiscovery_LEDOff(LED3); // Off Green Led

STM32vldiscovery_LEDOff(LED4); // Off Blue Led

int count = 0;

int delay_n = 600000;

while (1)

{

if (0 == STM32vldiscovery_PBGetState(BUTTON_USER))

{

switch(count) {

case 0:

Delay(delay_n);

STM32vldiscovery_LEDOn(LED3);

Delay(delay_n);
