6. Hands-On Programming Examples with MicroPython
Let’s get our hands dirty with some real-world MicroPython code!
Example 1: Blinking an LED
import machine
import time
led = machine.Pin(25, machine.Pin.OUT)
while True:
led.toggle()
time.sleep(0.5)
This simple code snippet demonstrates how to control an LED connected to pin 25 of a microcontroller. The LED will blink continuously with a 0.5-second delay.
Example 2: Reading Sensor Data
from machine import ADC
import time
sensor = ADC(0)
while True:
reading = sensor.read_u16()
print("Sensor reading:", reading)
time.sleep(1)
This code reads data from an analog sensor connected to ADC channel 0 and prints the readings to the console every second.
7. Diving into MicroPython Bytecode: What You Need to Know
MicroPython doesn’t directly execute your Python code. Instead, it compiles your code into a compact intermediate representation called bytecode.
Here’s the gist:
- Compilation: When you save a MicroPython file (e.g., main.py), it’s compiled into bytecode (e.g., main.mpy).
- Execution: The MicroPython interpreter then executes this bytecode, line by line.
This bytecode representation offers several benefits:
- Compactness: Bytecode is generally more compact than the original source code, saving precious memory on microcontrollers.
- Portability: Bytecode is platform-independent, allowing you to share pre-compiled code across different microcontroller architectures.
- Faster Execution: The interpreter can execute bytecode faster than parsing and executing the original source code.
