Small white beginners STM32F205VET6, try to light up the board PB7 (leds), did not succeed,
The HTML code is as follows, to show just a little, is involved in not delay, not visible to the naked eye?
In addition, initialize the clock function is which one? __GPIOB_CLK_ENABLE (); ?

Int main (void)
{

HAL_Init ();

/* Configure the system clock to 120 MHz */
SystemClock_Config ();

/* the Add your application code here */
Infinite loop/* */
Led_Init_PB7 ();
}

Void Led_Init_PB7 (void)
{

GPIO_InitTypeDef My_GPIO_Init;

__GPIOB_CLK_ENABLE ();

My_GPIO_Init. Pin=GPIO_PIN_7;

My_GPIO_Init. Mode=GPIO_MODE_OUTPUT_PP;

My_GPIO_Init. Speed=GPIO_SPEED_FAST;

My_GPIO_Init. Pull=GPIO_PULLUP;

HAL_GPIO_Init (GPIOB, & amp; My_GPIO_Init);

HAL_GPIO_WritePin (GPIOB, GPIO_PIN_7, GPIO_PIN_SET);

//GPIO_Init (LED_GPIO_PORT, & amp; GPIO_InitStructure);
}

CodePudding user response:

Function to run to the outside bracket {} is returned, and general MCU application is not allowed in this return, so your main () function needs to contain an infinite loop, prevent it returns,

CodePudding user response:

Your code framework inside tips you have to have an Infinite loop/* */, but you ignore it,,,,

Above two good, give opinions have tried, no

All posted?
Seems to have enough, confirm the high level or low level light? If it is low level light requires low level will be bright,
