Arduino STEAMI Sample

A collection of Arduino (PlatformIO) sample projects for the STM32WB55 microcontroller. This repository demonstrates various features such as LED control, button input, BLE communication, sensors, displays, and simple interactive demos — ideal for STEAM education and embedded experimentation.

Each folder contains standalone .cpp sample files.

How It Works

This project uses a simple approach:

Samples are included directly in src/main.cpp using #include.

Example:

#include <Arduino.h>
#include "../LED/blink.cpp"

void setup() {
  setup_blink();
}

void loop() {
  loop_blink();
}

Each sample must define:

• a setup_<name>() function
• a loop_<name>() function

---

Switching Between Samples

To run a different example, simply edit src/main.cpp:

#include <Arduino.h>

// Select your sample here:
#include "../LED/blink.cpp"
// #include "../BUTTON/read_button.cpp"
// #include "../BLE/advertiser.cpp"

void setup() {
  setup_blink();   // change accordingly
}

void loop() {
  loop_blink();    // change accordingly
}

Comment/uncomment the desired sample and update the function calls.

Requirements

Hardware

• STM32WB55 development board

Software

• PlatformIO
• Python 3.x

Installation

Install PlatformIO Core:

pip install platformio

Verify installation:

pio --version

---

Build, Upload and Monitor

From the root of the project:

pio run -t clean
pio run -t upload
pio device monitor -b 115200

---

Available Examples

• LED blinking : LED/blink.cpp

---

Notes

• This project intentionally uses a simple and beginner-friendly structure
• .cpp files are directly included (not standard C++ practice, but practical for quick experimentation)
• Only one sample should be included at a time in main.cpp

---

Goal

Provide a simple, hackable, and educational environment to explore embedded programming on STM32WB55 using Arduino and PlatformIO.
