Using the REPL Prompt
Using the Pymakr Plugin, open and connect a device or use serial terminal (PuTTY, screen,
picocom, etc). Upon connecting, there should be a blank screen with a flashing cursor. Press
Enter and a MicroPython prompt should appear, i.e.
>>>
. Let’s make sure it is working with
the obligatory test:
>>> print( "Hello LoPy!" )
Hello LoPy!
In the example above, the
>>>
characters should not be typed. They are there to indicate
that the text should be placed after the prompt. Once the text has been entered
print("Hello LoPy!")
and pressed
Enter
, the output should appear on screen, identical to
the example above.
Basic Python commands can be tested out in a similar fashion.
If this is not working, try either a hard reset or a soft reset; see below.
Here are some other example, utilising the device's hardware features:
>>> from machine import Pin
>>> led = Pin( 'G16' , mode=Pin.OUT, value= 1 )
>>> led( 0 )
>>> led( 1 )
>>> led.toggle()
>>> 1 + 2
3
>>> 5 / 2
2.5
>>> 20 * 'py'
'pypypypypypypypypypypypypypypypypypypypy'
Resetting the Device
If something goes wrong, the device can be reset with two methods. The first is to press
CTRL-D
at the MicroPython prompt, which will perform a soft reset. A message, as following,
will appear:
