Thank you. This works and is running. But seen there is nothing new here posted several years now. Not able to read the GPIO.
If tour operating system is the native RaspbianOS It should be available through APT package manager system just likes any Debian based system. Just sudo apt-get install wolfram-*
Ok./. was able to install from the Root . But the WritePin 4 does not bring the led to high . Anyone has this issue?
