Lab 1: LED Animations

Overview​

The first lab introduces the full toolchain: create an STM32Cube project, simulate it in Proteus, and drive LEDs from the STM32F103C6. You start from a single blinking LED and build up to traffic lights, a 7-segment display and a 12-LED analog clock.

Objectives​

  • Create and configure an STM32Cube project; generate code and export a .hex.
  • Build and run a Proteus simulation with the STM32F103C6.
  • Control GPIO outputs: HAL_GPIO_TogglePin / HAL_GPIO_WritePin, HAL_Delay.

Hardware & Tools​

  • STM32F103C6, LED-RED / LED-YELLOW / LED-GREEN, 7SEG-COM-ANODE, resistors.
  • PA5 is wired to the on-board LED; for the 7-segment, segments connect to PB0–PB6 (active-low: a segment turns on when the pin is logic 0).
while (1) {
  HAL_GPIO_TogglePin(LED_RED_GPIO_Port, LED_RED_Pin);
  HAL_Delay(1000); // blink every 1s
}

Exercises​

  1. Two LEDs (PA5/PA6) toggling every 2 s.
  2. A single-direction traffic light (red 5 s, yellow 2 s, green 3 s).
  3. A 4-way traffic light with 12 LEDs.
  4. display7SEG(int num) — show digits 0–9 on one 7-segment.
  5. Integrate the 7-segment as a countdown for the 4-way traffic light.
  6. A new schematic with 12 LEDs arranged as an analog clock (PA4–PA15).
  7. clearAllClock() — turn off all 12 clock LEDs.
  8. setNumberOnClock(int num) — light the LED for position 0–11.
  9. clearNumberOnClock(int num) — turn off the LED for position 0–11.
  10. Integrate everything: show hour/minute/second with 3 lit LEDs.

Report & Submission​

For each exercise, capture the Proteus schematic and present your source code (the while loop and any helper functions). Submit on BKeL.
