Low-Cost TFT Instrument Cluster with Telematics

Overview

This reference design completely meets all customer requirements for an instrument cluster with telematics. It includes connectivity, tell-tale indicators, Wi-Fi mirroring of a mobile screen, Bluetooth® Low Energy (LE) connection, and brightness control of a TFT and camera image display.

System Benefits:

  • Cost-effective, compact, and simple real-world vehicle instrument cluster to achieve graphics and connectivity. ​
  • Sample application software to jumpstart the application development. Sample firmware is Bare Metal C code and does not require any Linux/Android OS know-how to start development.​
  • Ready connectivity options available on the reference board - Wi-Fi, Bluetooth LE, Ethernet, GPS, and GSM-4G.​
  • Independent dual port CAN enables connection with other ECUs on the vehicle bus and also provides a separate interface for a diagnostic port.​
  • Eliminates expensive SerDes camera interface, replacing it with HD Link that interfaces to a low-cost analog camera via Single Twisted Pair [UTP/STP] connection without losing video quality.​
  • Support for cellphone-like UI using popular tools such as Qt, Candera, etc. is available.
