1536.2 Prerequisites
Before diving into this chapter, you should be familiar with:
- Software Prototyping Overview: Understanding of prototyping stages and framework selection
- Programming Paradigms and Tools: Basic programming concepts and version control
1536.3 Arduino IDE
Description: Simplified IDE for Arduino and compatible boards (ESP32, ESP8266, STM32 with add-ons).
Features: - Simple interface with minimal configuration - Extensive library manager - Built-in examples for learning - Serial monitor for debugging
Strengths: - Beginner-friendly - Fast setup and compilation - Massive community and libraries - Cross-platform (Windows, macOS, Linux)
Limitations: - Limited code intelligence (no advanced autocomplete) - Basic debugging capabilities - Less suitable for large projects
Best For: - Beginners and hobbyists - Quick prototyping - Simple to moderate complexity projects - Educational purposes
Getting Started:
void setup() {
Serial.begin(9600);
pinMode(LED_BUILTIN, OUTPUT);
}
void loop() {
digitalWrite(LED_BUILTIN, HIGH);
delay(1000);
digitalWrite(LED_BUILTIN, LOW);
delay(1000);
}1536.4 PlatformIO
Description: Professional IDE extension for VSCode supporting 1000+ boards and frameworks.
Features: - Unified development for multiple platforms - Advanced IntelliSense code completion - Built-in debugger support - Library dependency management - Unit testing framework - Static code analysis
Strengths: - Professional development experience - Consistent environment across platforms - Better for large, complex projects - Git integration and collaboration tools
Limitations: - Steeper learning curve - More complex configuration - Heavier resource usage
Best For: - Professional IoT development - Large or complex firmware projects - Teams requiring collaboration - Projects targeting multiple platforms
platformio.ini Example:
[env:esp32dev]
platform = espressif32
board = esp32dev
framework = arduino
lib_deps =
adafruit/Adafruit BME280 Library
knolleary/PubSubClient
monitor_speed = 1152001536.5 Manufacturer-Specific IDEs
STM32CubeIDE: - STMicroelectronics official IDE - Graphical pin configuration - HAL (Hardware Abstraction Layer) code generation - Professional debugging with ST-Link
ESP-IDF: - Espressif’s native framework for ESP32 - More control than Arduino framework - FreeRTOS integration - Advanced features (Wi-Fi, Bluetooth stacks)
Particle Workbench: - Cloud-connected development - OTA flashing and debugging - Fleet management integration
Advantages: - Optimized for specific hardware - Access to advanced features - Professional support
Disadvantages: - Platform lock-in - Steeper learning curve - Limited cross-platform portability
1536.6 Python Development for IoT
Thonny: - Beginner-friendly Python IDE - MicroPython support for microcontrollers - Simple interface, great for learning
VS Code with Python Extensions: - Professional Python development - Jupyter notebook support - Raspberry Pi remote development
Jupyter Notebooks: - Interactive development and exploration - Excellent for data analysis and visualization - Documentation with code
Best For: - Raspberry Pi and Linux-based systems - Data processing and analytics - Rapid prototyping with high-level language - Machine learning integration
