Make sure your Pico is plugged in via USB, and that you have disconnected CoolTerm. have a go yourself, and check the end of the video if you need help! tim2 = Timer() and initialised it to call tick with a different frequency. I wonder what would happen if we declared another timer eg.
tim.init(freq=3.5, mode=Timer.PERIODIC, callback=tick)Īnd with that, our LED blinks with a regular frequency. Now press enter a few times until the prompt returns to normal >įinally, we initialise the timer with a frequency, and set it to call the tick() function we just defined. these are just to show what the terminal will read-back) from machine import Timer We'll import the Timer package, create a timer, and define a function to toggle the LEDĮnter the following code (don't include the.

We have manual control of the LED, now let's set it up to blink automatically. We can also use toggle() which will toggle the state of the LED. The value() function sets the state of the LED: 1 is on, 0 is off. We'll need to import the Pin package to control the pin, and set the pin to an OUTput so it can drive the LED. Now we'll drive the onboard LED connected to pin 25. This interactive programming interface is called the REPL (Read Evaluate Print Loop) - it's super useful for testing out commands and quickly prototyping bits of code. Our Pico has just executed its first line of code! Hello, World! Enter the command print("hello world!") and the Pico should execute the print statement, displaying the text back on the next line. Now we can execute Python code interactively on our Pico. In the Terminal menu, set the Terminal Mode to Line Mode

You can check which port is assigned to your Pico by opening device manager and looking for the USB Serial Device (Windows: Start > Settings > Device Manager) Navigate to where you downloaded CoolTerm and run CoolTerm.exeĬlick Options and select your Pico's port.
