scratchClient is software especially for raspberryPi which allows scratch 1.4\u00a0 or scratch 2 to use hardware on the pi.
\nscratchClient is written in python, so no compiling step is needed.<\/p>\n
Installation and usage instructions are in the documentation.
\nSamples are in the code distribution.<\/p>\n
Download code distribution: Documentation is included in the download. Here are direct links: Quick install procedure. Please note the quite long line in the script. Be sure to copy till the end of line. Incompatibility Issue:<\/strong> \u00a0If you have tornado 5.0.x and scratchClient before 2018-04-02, then either update scratchClient to latest (be sure to make a backup copy of your configurations) or downgrade tornado to 4.5.3.<\/em><\/p>\n <\/p>\n Change history:<\/p>\n 2018-11-19\u00a0 added MPR121 device.

\npython3 is recommended to run scratchClient.
\npython2 should not be used.<\/p>\ncd ~\r\nwget -O scratchClient.tar.gz http:\/\/heppg.de\/download\/scratchClient\/scratchClient.tar.gz\r\ntar xzf scratchClient.tar.gz\r\nchmod +r -R scratchClient\/\r\nsudo apt-get update\r\nsudo apt-get install python-pip python-dev python-smbus \r\nsudo apt-get install python3-pip python3-dev python3-smbus \r\nsudo pip install tornado mako==1.0.6 spidev pyserial intelhex\r\nsudo pip3 install tornado mako==1.0.6 spidev pyserial intelhex\r\n<\/code><\/pre>\n
\n
\nWith the newest tornado versions 5.0.x, there is an incompatibility with older scratchClient releases.
\nThe problem is: scratchClient is working with scratch 1.4, but data from scratchClient to scratch2 are not transferred.
\n<\/em>How to find out if you are affected: Please check scratchClient version and tornado version
\n<\/em><\/p>\npython3 src\/scratchClient.py -version\r\npip3 freeze | grep tornado<\/em><\/pre>\n
sudo pip3 uninstall tornado\r\nsudo pip3 install tornado==4.5.3<\/em><\/pre>\n
