In this tutorial learn how to start coding MicroPython using PyCharm with the Raspberry Pi Pico or Raspberry Pi Pico W. This can be advantageous because PyCharm can be a preferable environment to write code for many programmers.
Step 1-) Download PyCharm
The community version is fine for this work.
Step 2-) Install MicroPython on Pico
- Plugin the device into the computer while holding the bootsel button.
- Go to https://micropython.org/download/ and download the latest version for the Pico or Pico W
- Drag the UF2 file onto your Pico once it is done downloading. *It should show up on your Desktop as RP1-RP2.
- Once it is done, the RP1-RP2 will disappear.
- Unplug and replug the Pico (without holding the bootsel). You need to do this so PyCharm can find the device.
Step 3-) Install MicroPython Plugin in PyCharm
- Open PyCharm, go to Plugins, and download the MicroPython plugin.
- Restart the IDE
Step 4-) Write Code
- Go to File > Create Project. Create an environment as shown above.
- Go to Preferences and enable MicroPython as shown here below.
- You can find the device path on a Macbook in the terminal using the command `ls /dev/tty.*`
- On a Windows this would be a COM port.
- You can now run code on the device by right-clicking the file and selecting “Run ‘Flash <filename>‘“
- Add the following code to check if it works by blinking the LED
import machine import time led_pin = machine.Pin("LED", machine.Pin.OUT) # GPIO pin 25 controls the onboard LED while True: led_pin.toggle() # Toggle the LED state time.sleep(0.1) # Wait for 1 second
If you run it and you see the LED blinking you did everything correctly, congrats!
- Very easy to set up, and benefits of IntelliSense in PyCharm
- Good for very simple projects
- You cannot edit files directly on the device with the IDE
- You can only run code in the main.py file
- You cannot run files if you are connected with another IDE like Thonny
