I write simple program(flashing gpio PB_4) but nothing is hapend on that pin (arduino pin D5). I Wrote similar program on mbed IDE and pin is flashing. What is wrong?
int main(void)
{
int i=0;
RCC_APB2PeriphClockCmd(RCC_APB2Periph_GPIOB, ENABLE);
GPIO_InitTypeDef gpio;
GPIO_StructInit(&gpio);
gpio.GPIO_Pin = GPIO_Pin_4;
gpio.GPIO_Mode = GPIO_Mode_Out_PP;
GPIO_Init(GPIOB, &gpio);
while (1) {
GPIO_SetBits(GPIOB, GPIO_Pin_4);
delay(100);
GPIO_ResetBits(GPIOB, GPIO_Pin_4);
delay(100);
}
}
