Calliope ML Racer

This project is for the Calliope Mini and uses Machine-Learning to solve a simple car driving game.

How to build

Tested with Windows 10:

Tools

yotta package in Python 2.7 (Anaconda)
GCC 7 arm-none-eabi (gcc-arm-none-eabi-7-2018-q2-update-win32.zip) (use version 7, not 8!)
CMake (cmake-3.14.5-win64-x64.msi)
Ninja (ninja-win.zip, v1.5.3)
SRecord (srecord-1.63-win32.zip)
Eclipse IDE for C/C++ Developers (eclipse-cpp-2019-03-R-win32-x86_64.zip)
Putty (putty-0.71.tar.gz)

URLs:

Install yotta

conda create -n calliope python=2.7
conda activate calliope
pip install -U yotta

run yt update once, it will download all required dependencies

install / unzip binaries

Unzip GCC and add gcc7-arm-none-eabi/bin to your PATH environment variable
install CMake and add CMake/bin to your PATH environment variable
unzip Ninja into a folder and add the folder to your PATH
unzip SRecord into a folder and add the folder to your PATH

Example toolchain setup

In Anaconda shell:

conda activate calliope
set PATH=\CALLIOPE\BIN\srecord163;%PATH%
set PATH=\CALLIOPE\BIN\gcc7-arm-none-eabi\bin;%PATH%
set PATH=\CALLIOPE\BIN\CMake\bin;%PATH%
set PATH=\CALLIOPE\BIN\ninja;%PATH%

Build

cd \CALLIOPE\git\calliope-ml-racer
yotta build

Flash

assume your Calliope device is mounted to "G:"

cd \CALLIOPE\git\calliope-ml-racer
copy build\calliope-mini-classic-gcc\source\calliope-project-template-combined.hex G:\

IDE

Install / unzip Eclipse
Toolchain is found automatically in PATH

Debug-Logging

Output written to ubit.serial.send(...) can be displayed using a serial terminal like PuTTY. Connect the Calliope via USB and look at the device manager, which COM-port is assigned:

Here it is "COM5". Then create a new serial session in PuTTY to COM5 with speed 115200:

Starting the PuTTY sessions opens a black window. As soon, as something is written from the Calliope program using ubit.serial.send("Hello!") this is displayed in this window. The connection is still esablished, if the Calliope is resettet using the reset button.

Ubuntu 18.04
