Practical Approaches for Usage of Raspberry Pis in Slow Control Systems — •Maik Biroth, Patrick Achenbach, Werner Lauth, and Andreas Thomas for the A2 collaboration — Institute for Nuclear Physics, Mainz

In nuclear physics single-board computers like Raspberry Pis are enjoying growing popularity for an usage in slow control applications based on a decentralized network infrastructure like EPICS. This work gives an overview of known everyday issues and approaches of detailed electronic solutions. Main topics are: How to convert NIM signals to the LVTTL level that they can be processed by the Raspberry Pi; how to build an uninterruptible power supply to avoid a corrupted file system after breakdown of the voltage; how to use an microcontroller as a front processor to reboot the computer if a software error leads to a crash of the network connection.
