/**
* @brief This is the device handler class for the SUS sensor. The sensor is
* based on the MAX1227 ADC. Details about the SUS electronic can be found at
* https://egit.irs.uni-stuttgart.de/eive/eive_dokumente/src/branch/master/400_Raumsegment/443_SunSensorDocumentation/release
*
* @details Datasheet of MAX1227: https://datasheets.maximintegrated.com/en/ds/MAX1227-MAX1231.pdf
*
2021-05-12 16:38:20 +02:00
* @note When adding a SusHandler to the polling sequence table make sure to add a slot with
* the executionStep FIRST_WRITE. Otherwise the communication sequence will never be
* started.
