This code controls three LEDs connected to GPIO pins on an STM32 microcontroller. Let's break it down step by step:

1. `HAL_GPIO_WritePin(GPIOC,GPIO_PIN_13,0);`: This line turns off the LED connected to pin 13 of GPIO port C.

2. `HAL_GPIO_WritePin(GPIOC,GPIO_PIN_14,0);`: This line turns off the LED connected to pin 14 of GPIO port C.

3. `HAL_GPIO_WritePin(GPIOC,GPIO_PIN_15,0);`: This line turns off the LED connected to pin 15 of GPIO port C.

4. `HAL_Delay(400);`: This line adds a delay of 400 milliseconds, which means the program will wait for 400 milliseconds before executing the next line of code.

5. The next series of lines follows a similar pattern, but they turn on one LED at a time while keeping the others off. For example:

  - `HAL_GPIO_WritePin(GPIOC,GPIO_PIN_13,0);` turns off the LED on pin 13.

  - `HAL_GPIO_WritePin(GPIOC,GPIO_PIN_14,1);` turns on the LED on pin 14.

  - `HAL_GPIO_WritePin(GPIOC,GPIO_PIN_15,0);` keeps the LED on pin 15 off.

  - Then there's another delay of 400 milliseconds.

6. This sequence repeats for each LED, cycling through different combinations of LEDs being on and off.

In essence, this code creates a pattern where the LEDs connected to pins 13, 14, and 15 of GPIO port C blink in a specific sequence, with each LED turning on and off at different times. The delay between each change in LED state determines the speed of the blinking pattern.
