maybe it's a good idea to use a small “industrie SDcard“ which should not be too expensive for using only the bootloader. This card combined with the RPi should be the unchangeable system for the Rex-ID.
With Linux on SSD/PiDrive or USB-HDD there is option for writing. Almost the Linux-logs do that and configuring Linux to avoid this costs lot of time (for newbies).
We would start with 2h demo and will license when PiDrive arrives.
With best regards
new verison of the REX Control System is out. At this occasion we have also improved our GitHub examples repository. Download the example projects from https://github.com/rexcontrols/REXexamp ... master.zip and navigate to the UniPi_examples folder. You are encouraged to visit the other folders as well...
