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.

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

# 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

# %%

# Application that displays data on a map and allows to modify the data in a

# Note: This application must not be executed using multiple workers, but only
# single-threaded (i.e. run with `python <name>`).
# See https://dash.plotly.com/sharing-data-between-callbacks for the reason.
