STM32 GPIO Push button LED blink. Easy Code snippets part - I

Board: Discovery STM32F4VGxx

Code Generated through: ST Cube MX. 

I generated the code with Cube MX. 

The GPIO pins are given in the STM Discovery Manual: 

http://www.st.com/content/ccc/resource/technical/document/user_manual/70/fe/4a/3f/e7/e1/4f/7d/DM00039084.pdf/files/DM00039084.pdf/jcr:content/translations/en.DM00039084.pdf

These are the config thing for clock:

Next is the code that you can put in the while loop to get GPIO toggleon Push button: 

if ( HAL_GPIO_ReadPin( GPIOA, GPIO_PIN_0 ) == GPIO_PIN_SET )

{

HAL_GPIO_WritePin( GPIOD, GPIO_PIN_14, GPIO_PIN_SET );

}

else

       {

HAL_GPIO_WritePin( GPIOD, GPIO_PIN_14, GPIO_PIN_RESET );

}

Now compile and download the code. 

Done..
