microbit

A few experiments with Microbit and Micropython.

Flashing the Microbit firmware

Micropython for Microbit

Flashing Micropython for the first time

Invoke uflash:

$ uflash
Flashing Python to: /run/media/edrdo/MICROBIT/micropython.hex

To check if everything is OK, now connect to the Microbit using a program like minicom. After connecting hit Control+C, then type help().

$ # Set device name appropriately (/dev/ttyACM0 in this example)
$ minicom -D /dev/ttyACM0  
Welcome to minicom 2.7.1

OPTIONS: I18n 
Compiled on Jul 28 2020, 00:00:00.
Port /dev/ttyACM0, 17:25:18

Press CTRL-A Z for help on special keys
>>> help()
Welcome to MicroPython on the micro:bit!

Try these commands:
  display.scroll('Hello')
  running_time()
  sleep(1000)
  button_a.is_pressed()
What do these commands do? Can you improve them? HINT: use the up and down
arrow keys to get your command history. Press the TAB key to auto-complete
unfinished words (so 'di' becomes 'display' after you press TAB). These
tricks save a lot of typing and look cool!

Explore:
Type 'help(something)' to find out about it. Type 'dir(something)' to see what
it can do. Type 'dir()' to see what stuff is available. For goodness sake,
don't type 'import this'.

Control commands:
  CTRL-C        -- stop a running program
  CTRL-D        -- on a blank line, do a soft reset of the micro:bit
  CTRL-E        -- enter paste mode, turning off auto-indent

For a list of available modules, type help('modules')
