Created June 21, 2020 21:22
A python class that allows to control a two-wheel robot with two AC motors on the Calliope Mini.
from calliope_mini import pin28, pin29, pin30
from utime import ticks_us, ticks_add
# Note: as the file is large and has long comments, use pyminifier before uploading to Calliope mini.
# Note: Some abstration is missing here and code is duplicated.
# This happens with a reason:
# MicroPython has only a very limited stack size and thus number of nested
# function calls is low.
# Because of that, code is repeated in different functions

Get Started With Calliope Mini on Windows

TigerJython

  • Download https://www.tjgroup.ch/download/TigerJython.msi
  • install the msi file without admin privileges using install.bat -- modify the target directory in that file
  • Execute <target>/bin/TigerJython.exe
  • Flash CalliopeMini with MicroPython -- this needs to be done only once so that MicroPython is installed on the Calliope
    • Plug in Calliope
    • Tools -> Devices -> micro:bit/Calliope
  • Tools -> Flash Target

Why you should catkin build a pure python package as well.

Why you should catkin build a pure python package as well, although nothing gets compiled:

When you build a package using catkin build, the path to the package is added to some variables in setup.bash. When setup.bash is sourced the next time, these variables are made part of the environment. Thus, tools like rosrun and roslaunch can find the executables/scripts and python may find modules.
