Story

Step 1: Setting Up Your Environment

Install STM32CubeIDE: Download and install STM32CubeIDE from the STMicroelectronics website.

Hardware Required:

STM32 Black Pill board
LEDs (3x)
Breadboard
Jumper wires
USB cable for programming
Hardware Required:STM32 Black Pill boardLEDs (3x)BreadboardJumper wiresUSB cable for programming

Step 2: Creating a New Project

Open STM32CubeIDE.
Go to File > New > STM32 Project.
Select the correct board part number (e.g., STM32F411CEU6 for the Black Pill).
Give your project a name and location.

Step 3: Configuring the Pins

In the Pinout & Configuration tab, configure three GPIO pins as output for the LEDs.
For example, use pins PA5, PA6, and PA7.
Set the pins to GPIO_Output mode.

Step 4: Clock Configuration

Ensure the system clock is configured correctly to provide accurate timing for the LED sequence.

Step 5: Coding the LED Sequence

Replace SystemClock_Config() and MX_GPIO_Init() with your actual configuration functions.
Add the rest of the patterns by toggling the GPIO pins accordingly.

Step 6: Building and Flashing the Code

Build the project by clicking on the Build button.
Connect the Black Pill board to your computer via USB.
Use the STM32CubeProgrammer to flash the compiled binary onto the board.

Step 7: Testing

After flashing, reset the board and observe the LEDs.
They should blink in the sequence you programmed.

Coding the LED Sequence

#include "main.h"

void HAL_GPIO_TogglePin(GPIO_TypeDef* GPIOx, uint16_t GPIO_Pin);

int main(void)
{
  HAL_Init();
  SystemClock_Config();
  MX_GPIO_Init();

  while (1)
  {
    // Pattern 100
    HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5, GPIO_PIN_SET);
    HAL_GPIO_WritePin(GPIOA, GPIO_PIN_6 | GPIO_PIN_7, GPIO_PIN_RESET);
    HAL_Delay(500); // Delay 500 ms

    // Add other patterns here following the same structure
    // ...

    // Pattern 110
    HAL_GPIO_WritePin(GPIOA, GPIO_PIN_5 | GPIO_PIN_6, GPIO_PIN_SET);
    HAL_GPIO_WritePin(GPIOA, GPIO_PIN_7, GPIO_PIN_RESET);
    HAL_Delay(500); // Delay 500 ms
  }
}
