How the micro:bit works with Python, one of the world's most popular programming languages. Python is a text-based language used widely in education, and by professional programmers in areas like data science and machine learning. Supported by a huge community of educators and computing experts, Python makes a great next step after block coding and is a perfect introduction to text-based programming.

Our online Python editor is designed with teachers and learners in mind: you can easily enlarge the text size for sharing on a large screen or whiteboard, download projects as Python text files or.

HEX files ready to flash onto a micro:bit. It also works with micro:bit classroom. Using a modern Chrome browser you can quickly and easily download programs direct to your micro:bit using webUSBand interact directly with your micro:bit using your computer keyboard using the Serial feature.

You can also add Python modules to extend your programs and easily use accessories. Let's start with the basics - making some words and a picture appear on your micro:bit's display.

Flash it to your micro:bit by downloading a hex file and transferring itor flash it by webUSBand see words and pictures appear on your micro:bit. You need to be very precise when coding in text-based languages, and Python is no exception. The spaces at the start of lines 6, 7 and 8 are important. These are called indentationsmade from four space characters or one press of the TAB key.

This is an infinite loop like the forever block in MakeCode or Scratch.

The instructions indented after while True: form part of the loop: your micro:bit will keep carrying out those instructions as long as it has power. Any instructions after while True: that are not indented won't run until the loop has finished. As well as showing a heart icon, you can use lots more built-in images with Python. Try different numbers from 0 to 9 to make each LED darker or brighter.

Not all pins are available to use, in most cases only pins 0, 2, 4, 5, 12, 13, 14, 15, and 16 can be used. The pins are available in the machine module, so make sure you import that first. Then you can create a pin using:. Usually you want to configure the pin to be input or output, and you do this when constructing it.

To make an input pin use:. You can read the value on the pin using:. To make an output pin use:. All pins except number 16 can be configured to trigger a hard interrupt if their input changes. You can set code a callback function to be executed on the trigger. We will make the function just print the pin:. An finally we need to tell the pins when to trigger, and the function to call when they detect an event:. We set pin 0 to trigger only on a falling edge of the input when it goes from high to lowand set pin 2 to trigger on both a rising and falling edge.

After entering this code you can apply high and low voltages to pins 0 and 2 to see the interrupt being executed. A hard interrupt will trigger as soon as the event occurs and will interrupt any running code, including Python code. As such your callback functions are limited in what they can do they cannot allocate memory, for example and should be as short and simple as possible.

Here you can find modules for different devices. Bluetooth module HC Drivers in the MicroPython source tree. These may be found under drivers:. NRF24L01 Provides two way checksummed radio communications with auto-retry in the 2. It also has other code for drones and robots including Madgwick sensor fusion and a driver for the BMP pressure altitude sensor. Now has a driver for the Bosch BNO which supports sensor fusion in hardware.

HDC humidity and temperature sensor. Microchip MCP high precision temperature sensor. MPLA2 barometric pressure sensor. Designed for ease of use. Rotary Encoders. HX load cell amplifier. Radio control wall sockets Sniff the signal from the remote and transmit it from code. EA support includes drivers for the onboard flash memory and LM75 temperature sensor. Touch GUI A touch interface library for the above displays. Cross-platform, uses SPI to minimise pin count.

You can redirect REPL to any framebuffer device. Two projects:. The interface offers guaranteed message delivery while coping with WiFi and server outages.

I later ordered the led matrix but I want to know how to get it to work with micropython and micro:bit. Any help is appreciated. Thanks -Will. There are generally two approaches you can take to write such a driver. The ambitious way and usually giving better results is to search for "max datasheet", download the pdf, read it, figure out what commands need to be sent to the chip to make it work, and do that in the library.

The bottom-feeder approach that I took is to take one or more existing libraries for other platforms, see what they do optionally, using the datasheet, understand whyand do the same thing. I have a MAXbased matrix at hand, so I can help you write the driver, if you want? In the meantime, I tried with a Wemos D1 Pro flashed with micropython.

Matrix8x8 spi, Pin 2 display. The module may be too large, in which case an out-of-memory error is flagged. The removal of pin. Instead of pin. But as I still got an import error, I tried to flash the whole library and I discovered that the module machine does not exists.Pin objects are commonly associated with a physical pin that can drive an output voltage and read input voltages.

The pin class has methods to set the mode of the pin IN, OUT, etc and methods to get and set the digital logic level. For analog control of a pin, see the ADC class. The allowed forms of the identifier and the physical pin that the identifier maps to are port-specific. Possibilities for the identifier are an integer, a string or a tuple with port and pin number. Access the pin peripheral GPIO pin associated with the given id.

If additional arguments are given in the constructor then they are used to initialise the pin. Any settings that are not specified will remain in their previous state. As specified above, the Pin class allows to set an alternate function for a particular pin, but it does not specify any further operations on such a pin. Pins configured in alternate-function mode are usually not used as GPIO but are instead driven by other hardware peripherals. The only operation supported on such a pin is re-initialising, by calling the constructor or Pin.

If a pin that is configured in alternate-function mode is re-initialised with Pin. INPin. OUTor Pin. Re-initialise the pin using the given parameters.

Only those arguments that are specified will be set. The rest of the pin peripheral state will remain unchanged. See the constructor documentation for details of the arguments. This method allows to set and get the value of the pin, depending on whether the argument x is supplied or not.

If the argument is omitted then this method gets the digital logic level of the pin, returning 0 or 1 corresponding to low and high voltage signals respectively. The behaviour of this method depends on the mode of the pin:. If the argument is supplied then this method sets the digital logic level of the pin.

The argument x can be anything that converts to a boolean. When setting the value this method returns None.
