Hi everyone,
I want to turn on a LED on my STM32F4-discovery board
Here is the code :
int main() {
// Enable the GPIO Clock
RCC_AHB1PeriphClockCmd(RCC_AHB1Periph_GPIOD, ENABLE);
// GPIO Configuration
GPIO_InitTypeDef GPIO_InitStruct;
GPIO_InitStruct.GPIO_Pin = GPIO_Pin_14; // Led 6 Blue selected
GPIO_InitStruct.GPIO_Mode = GPIO_Mode_OUT; // Mod out !
GPIO_InitStruct.GPIO_Speed = GPIO_Speed_50MHz; // 50 MHZ clock frequency
GPIO_InitStruct.GPIO_OType = GPIO_OType_PP; // Push pull mod
GPIO_InitStruct.GPIO_PuPd = GPIO_PuPd_UP; // Pull up
GPIO_Init(GPIOD, &GPIO_InitStruct);
// Turn on the LED
GPIO_SetBits(GPIOD, GPIO_Pin_14);
return 0; }
I'm using uvision 5.13.0.0
It compiles and flash succesfully but nothing happen after. I don't know what is wrong with this. I also tried with this :
STM_EVAL_LEDInit(LED6); STM_EVAL_LEDOn(LED6);
but there is no worked.
Can you help me ? Many thanks :)
