Abstract: Techniques are described for a lighting system in which light sources are controllable using signals sent over a wireless mesh network. During a commissioning process, a user interface (UI) may present a representation of nodes (e.g., light sources, sensors, controllers, etc.) that are broadcasting a wireless advertising signal. In response to a selection of a particular node, a wireless message may be sent to instruct the selected node to provide a visual indication of its presence, such as a flashing light. The visual indication may enable a user to discern the physical location of the node, such that each node may be added to the mesh network and, in some instances, to a group of nodes. The UI may also enable the definition of scenes, where each scene describes the brightness level or other operating characteristics of particular light source(s) and/or group(s) of light sources when the scene is active.

Abstract: A memory control component outputs a memory write command to a memory IC and also outputs write data to be received via data inputs of the memory IC. Prior to reception of the write data within the memory IC, the memory control component asserts a termination control signal that causes the memory IC to apply to the data inputs a first on-die termination impedance during reception of the write data followed by a second on-die termination impedance after the write data has been received. The memory control component deasserts the termination control signal to cause the memory IC to apply no termination impedance to the data inputs.
