SPI Round Robin Mode for Single-Cycle MUX Channel Sequencing. SPI round robin mode is an SPI mode applicable for MUX devices control. It allows the MUX output to connect to the next input channel sequentially in just one clock cycle. Configurations can be made such as: clock edge to use (rising/falling), ascending/descending channel sequence, and enabling/disabling the channels to go through. The device supersedes an ADC with built in sequencing and is applicable to multiplexing, switching, instrumentation, process control and isolation applicationwhile retaining SPI device control and operation.

A sensor in a building HVAC system includes a transducer configured to measure a variable in the building HVAC system and to generate a sensor reading indicating a value of the measured variable. The sensor includes a communications interface configured to provide the sensor reading to a control device in the building HVAC system and a near field communication (NFC) circuit separate from the communications interface. The NFC circuit is configured to facilitate bidirectional NFC data communications between the sensor and a mobile device. The sensor includes a processing circuit having a processor and memory. The processing circuit is configured to wirelessly transmit data stored in the memory of the sensor to the mobile device via the NFC circuit, wirelessly receive data from the mobile device via the NFC circuit, and store the data received from the mobile device in the memory of the sensor.

A method for integrating a further bus subscriber into a bus system, and a bus system, having a master module and subscribers disposed in series, includes the temporally consecutive method steps: in a first method step, the further bus subscriber transmits a data packet to the master module in order to log in to the master module, in a second method step, a bus subscriber disposed between the further bus subscriber and the master module stops the data packet and checks whether the bus system has already received a release, in a third method step, the first bus subscriber forwards the data packet to the master module if the bus system has not yet received a release, or in a third, in particular an alternative, method step, if the bus system has already received a release, the bus subscriber stores the data packet and waits until the release of the bus system is revoked and after the release has been revoked, forwards the stored data packet to the master module.
