2.4 GHz RF Smart Remote reference design targets TVs and set-top boxes
The reference design includes native support for a multi-gesture TouchPad™, QWERTY keyboard, and motion control that all combine to deliver a rich, intuitive, and engaging end-user experience for advanced control and browsing of all types of modern digital content and services including audio, video, gaming, web browsing, social media, and online shopping.
The nRFready™ 2.4 GHz RF remote control features a multi-touch enabled TouchPad™ from Synaptics, a miniaturized QWERTY keyboard, a 6-axis motion sensing solution from Invensense, an ultra low power accelerometer from STMicroelectronics.
The combination of Nordic’s nRF24LE1 SoC and Gazell™ 2.4 GHz RF protocol stack also ensures a high performance, ultra low power, and cost efficient remote control implementation. Originally designed for PC peripherals, this radio and protocol combination delivers the bandwidth, latency, and co-existence performance necessary to seamlessly support all the nRFready™ RF Smart Remote’s advanced features in even the most challenging 2.4 GHz operating environments. The reference design even features an IR (Infrared) LED that can be used to add support for legacy IR-controlled equipment too.
To let end users easily navigate through the rich content available on Internet-enabled TVs, the Synaptics multi-touch-enabled TouchPad™ provides both a familiar and modern user experience to consumers by supporting standard pointing, scrolling and tapping gestures; a range of more sophisticated multi-touch gestures including scroll, zoom, flick, and rotate; plus custom gestures with an enhanced user interface. This helps to create a fully interactive and intuitive Internet-enabled TV experience.
The ultra low power accelerometer from ST Microelectronics is used by the nRFready™ Smart Remote for intelligent power management, and can also support additional advanced control and browsing features such as orientation detection.
Motion sensing is based on an InvenSense MPU-6050 MotionProcessing™ solution that InvenSense claims is the world’s first and smallest integrated 3-axis gyroscope plus 3-axis accelerometer combination, and includes InvenSense’s Digital MotionProcessor™ and 9-axis MotionFusion™ algorithms built-in. This is said to make it an ideal implementation for the remote control of products such as Smart TVs and game consoles because it enables point-and-click intuitiveness and gesture-based shortcuts for advanced navigation and control. The included InvenSense embedded MotionApps™ software also provides platform support for Microsoft Windows, Linux, and Android.
The nRFready™ 2.4 GHz RF Smart Remote reference design kit (Nordic product code: nRF6920) includes a Nordic Smart Remote baseboard, Smart Remote 2.4 GHz RF radio module, 2.4 GHz RF USB dongle, programming adapter, and a complete set of design files, software source code, and supporting documentation. It is available today.
