* @brief This is the device handler class for the SUS sensor based on the MAX1227 ADC.

|
*
|
|
* @details
|
|
* Datasheet of MAX1227: https://datasheets.maximintegrated.com/en/ds/MAX1227-MAX1231.pdf
|
|
* Details about the SUS electronic can be found at

|
|
* @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.
