sam_grove 0:6219434a0cb5 24 * @brief LSS offers the possibility to inquire and change the settings of certain parameters of the local layers on
sam_grove 0:6219434a0cb5 25 * a CANopen module with LSS Slave capabilities by a CANopen module with LSS Master capabilities via the
sam_grove 0:6219434a0cb5 26 * CAN Network.
sam_grove 0:6219434a0cb5 27 * The following parameters can be inquired and/or changed by the use of LSS:
sam_grove 0:6219434a0cb5 28 * - Node-ID of the CANopen Slave
sam_grove 0:6219434a0cb5 29 * - Bit timing parameters of the physical layer (baud rate)
sam_grove 0:6219434a0cb5 30 * - LSS address (/2/ Identity Object, Index 1018H)
