In this article onwards let’s understand the procedure to turn on the LED.<\/span><\/p>\n

To write a code to turn on the LED is not that easy. That’s what makes the embedded system programming so unique that you must know memory map, peripheral registers, peripheral register addresses, hardware connections, etc. <\/span><\/p>\n

 <\/p>\n

Procedure to turn ON the LED<\/b><\/span><\/p>\n

1. Identify the GPIO port(a peripheral)used to connect the LED<\/b>.<\/b> <\/span><\/span><\/p>\n

We have identified that. That is <\/span>GPIOD<\/b>.<\/span><\/span><\/p>\n

2. Identify the GPIO  pin where the LED is connected<\/b>.<\/b><\/span><\/p>\n

 We also identified pin number 12 of Port D.<\/span><\/span><\/p>\n

3. Activate the GPIOD peripheral<\/b><\/span>:<\/span> By default in the microcontroller most of the peripherals are dead, you have to activate them. So, activating a peripheral is nothing but enabling the clock for them.<\/span><\/span><\/p>\n
