The SimpleLink SDK includes TI Drivers, a robust set of intuitive, functional APIs that offer portable, feature-rich access to peripherals. The TI Drivers API exposes the functionality of the hardware-specific drivers in the same way across all TI SimpleLink devices, giving developers portable, feature-rich access to a variety of peripherals. TI drivers are open source [Berkeley Software Distribution license (BSD)] and built on a hardware abstraction layer, offering full access to the device’s complete capability.
The SimpleLink™ SDK features POSIX (Portable Operating System Interface), which is a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems. Through POSIX-compliant APIs, developers can maintain 100% application code portability between various OS/kernels.
The SimpleLink SDK comes integrated with TI-RTOS. Checkout the trainings below to learn about multi-threaded applications & the features available with TI-RTOS.
This section covers the basics of mechanical water meters and the principle of operation for impeller based water meters. There are multiple standards for water meters around the world; the EN ISO 4064 is relevant to all European countries and has been adopted under a different name in some other regions as well.
Water and heat meters share multiple system building blocks, such as the metrology sub-system and the application sub-systems, the Wireless communications part, the InfraRed optical port or the power solution. In this section, we will cover a new ultra-low cost single-chip LC-sensing solution utilizing the CC1350 Wireless MCU and its Sensor Controller Engine. Two external LC-tanks with a TI FemtoFET device each implement two rotation detection sensors, which measure the rotation of a half-metal/half-nonmetal disc, often used in mechanical water meters.
Some EU standards like EN1434-3 for heat meters require optical interface as per EN62056-21, where two separate IR LEDs are used (one for receive and one for transmit direction). TIDA-01212 shows an alternative approach, which uses a single IR LED to implement a bi-directional IrDA PHY link with 9.6 kbps in half-duplex mode. The design approach can the system reduce cost of any smart (sub-)metering device by replacing the legacy optical IrDA PHY modules with two separate LEDs.
