MicroPython: The Mini Power of Embedded Systems!
Python is one of the most popular programming languages in the world, and MicroPython is its superhero version in the embedded field. Imagine that microcontrollers and microcontrollers, which once required complex C language programming, can now be directly controlled using the friendly language of Python! For programmers and makers who want to play with hardware, MicroPython is an incredible existence. It not only retains the simplicity and elegance of Python but can also run on hardware with extremely limited memory, making it a revolution in embedded development.
What is MicroPython?
MicroPython is a lean implementation of the Python 3 language, written in C, and is a complete Python compiler and runtime system that runs on microcontroller hardware. It includes a small portion of the Python standard library, optimized to run on microcontrollers and constrained environments. It has an interactive prompt (REPL) that can immediately execute supported commands. In addition to the core Python library, it includes modules that allow programmers to access low-level hardware and strives for compatibility with standard Python (CPython).
MicroPython can run on various embedded hardware platforms, such as STM32, ESP8266/ESP32, CC3200, etc., with STM32 and ESP8266 being mature and fully functional as the main application platforms.
Comprehensive Hardware Support
MicroPython supports a wide range of development boards, such as ESP8266, ESP32, STM32, Raspberry Pi Pico, etc. Whether you want to create IoT projects, sensor monitoring, or interesting hardware interactions, it can meet your needs.
Quick Start with GPIO Control
import machine# Define LED pinled = machine.Pin(2, machine.Pin.OUT)# Blink LEDled.on() # Turn onled.off() # Turn offThis piece of code can control the LED on the development board, so easy!
Analog and Digital Readings
# Read analog sensoradc = machine.ADC(0)sensor_value = adc.read()With just a few lines of code, you can read the values from analog sensors, such as temperature, light intensity, etc.
Network Connection Made Simple
import network# WiFi connectionwlan = network.WLAN(network.STA_IF)wlan.active(True)wlan.connect('WiFi Name', 'WiFi Password')Hey, connecting to WiFi is that simple!
Interrupts and Timers
def button_handler(pin): print("Button pressed!")# Set up interruptbutton = machine.Pin(14, machine.Pin.IN, machine.Pin.PULL_UP)button.irq(trigger=machine.Pin.IRQ_FALLING, handler=button_handler)Giving hardware “ears” and “responses” is a sure thing!
File System Operations
# Read and write fileswith open('data.txt', 'w') as f: f.write('Sensor data')with open('data.txt', 'r') as f: content = f.read()Even micro systems can perform file read and write operations.
Friendly Reminders
- Pay attention to RAM and Flash size when purchasing development boards
- Understand your hardware specifications and the level of MicroPython support in advance
- Not all Python syntax is fully supported, adjustments may be necessary
MicroPython is just that awesome: small yet powerful, making embedded development as fun as building with blocks!
