These steps assume you have installed MIStudio on your development system already. This can be a trial or non-trial installation.

In the step below “Setup the MIX Runtime Directory” you will be transferring all the files from this installation's MIStudioSuite/MIX directory to the “mixruntime” directory on the pi.

ssh into your Raspberry Pi system and check the java version:

java -version

you should see that it runs by printing a version 1.8.xxxxxx

openjdk version "1.8.0_222"
....

if you do not see that it is installed, or if it is not version 8, you will need to install jdk 8. You can install openjdk or corretto.

The serial port library will need to be installed. See http://angryelectron.com/rxtx-on-raspbian/ for more details.

sudo apt-get install librxtx-java

this installs so's into /usr/lib/jni and RXTX jar into /usr/share/java, which is the expected location for the MIX software.

The MIX runtime should run as a dedicated “mix” user with a secure password, but you can test MIX using the default user for your system, for example, for user “pi”.

To test as user “pi” make a directory called “mixruntime” in the pi home directory.

ftp the contents of the MIX directory on your development system to this “mixruntime” directory on the pi.

The mixruntime directory on the pi should have a subdirctory called “scripts”. Copy the runmix.sh file from the scripts directory into the main mixruntime directory. Likewise, there is a log4j directory. Copy the log4j.console.xml file from the log4j directory into the main mixruntime directory.

cp ./scripts/runmix.sh .
cp ./log4j/log4j.console.xml .

Make the file “runmix.sh” executible.
