EtherCAT Slave Device and Multi-Protocol Industrial Ethernet Reference Design

This reference design implements a cost-optimized, high-EMC immunity EtherCAT slave (dual port) with an SPI interface to the application processor. The hardware design leverages the AMIC110 industrial communications processor to support multi-protocol industrial Ethernet and fieldbuses. The design is powered by a single 5V supply; the PMIC generates all necessary on-board rails. The EtherCAT slave stack can run on the AMIC110 or on an application processor using the Serial Peripheral Interface (SPI). Using hardware switches, the AMIC110 can be configured to boot EtherCAT slave firmware from SPI flash memory or from the application processor via SPI. The design has been tested for IEC61800-3 EMC immunity with a standard industrial PLC running an EtherCAT master. JTAG interface speeds custom firmware development.

People Counting Reference Design for Demand Controlled Ventilation via 3D Time of Flight (ToF)

The Demand Controlled Ventilation People Counting Reference Design with 3D Time of Flight (ToF) is a subsystem solution that uses TI's 3D ToF image sensor and tracking and detection algorithms to count people in a given area, enabling high resolution and high precision. The sensor technology was developed in standard CMOS, enabling high levels of system integration at low system cost. Because ToF image sensors process visualization data in three dimensions, the sensor can detect the precise shape of the human body and track a person's movement and position (including minute changes in movement) with unprecedented accuracy. As a result, ToF cameras can perform real-time people counting and people tracking functions more efficiently than traditional surveillance cameras and video analytics.

WF111 development kit design information

The WF111 is a fully integrated single 2.4 GHz band 802.11 b/g/n module designed for portable and battery-powered applications requiring Wi-Fi connectivity. The WF111 integrates an IEEE 802.11 b/g/n radio, antenna or U.FL antenna connector, and SDIO host interface. It provides a low-cost and simple Wi-Fi solution for devices running an operating system and an onboard TCP/IP stack, but still offers the advantages of modules - small size, certification and ease of integration. Silicon Labs also provides WF111 drivers for Linux and Android operating systems. WF111 has hardware support for Wi-Fi encryption protocols.
