First Project with the STM32WB5MMGH6

Writing a basic LED blinking program

Creating a basic LED blinking program is an excellent way to start your journey with the STM32WB5MMGH6 module. This simple project helps you understand how to control GPIO pins and interact with external components. To begin, you need to connect an LED to one of the GPIO pins on your MicroMod carrier board. Use a resistor in series with the LED to limit the current and protect the circuit.

Once the hardware is ready, open your development environment. If you are using the Arduino IDE, you can follow the MicroMod STM32WB5MMG Hookup Guide. This guide provides a step-by-step example of how to create a blinking LED program. It includes details on setting up the hardware and configuring the software. The example uses straightforward code to toggle the LED on and off at regular intervals.

Here’s a sample code snippet to get you started:

void setup() {
  pinMode(LED_BUILTIN, OUTPUT); // Set the LED pin as an output
}

void loop() {
  digitalWrite(LED_BUILTIN, HIGH); // Turn the LED on
  delay(1000);                     // Wait for 1 second
  digitalWrite(LED_BUILTIN, LOW);  // Turn the LED off
  delay(1000);                     // Wait for 1 second
}

This code initializes the LED pin as an output in the setup() function. The loop() function alternates the LED state between on and off, with a one-second delay between each change. You can modify the delay values to adjust the blinking speed.

Tip: Always double-check your connections and ensure the LED is connected to the correct GPIO pin specified in your code.

Uploading code to the STM32WB5MMGH6
