The Texas Instruments microcontrollers in the MSP 430 series offer four ways to save power in operation in such a way as to allow for consistent reduction of the electricity consumed. Code Composer Studio programming environment also provides support in making low-power applications. In addition to these, the MSP430FR2433 microcontroller with ferroelectric RAM allows data to be stored even in the absence of power voltage. In view of these properties of the microcontroller, a data logger application has been developed to monitor the quality of the environment in a building. Given that the MSP430FR2433 microcontroller can process both analog and numerical signals, the device monitors the temperature, humidity, carbon dioxide concentration and amount of light present in the enclosure. Thanks to energy-saving mechanisms and the possibility of keeping information for an indefinite period without the need for energy consumption, the ambient quality monitoring device can operate for a long time in places without energy resources. The device has also been tested with good results for autonomous operation using solar energy and has also been used to determine the energy performance of buildings.

“…Due to increasing demands, higher data sharing and decrease of power consumption are expected from wireless communication systems [1]. Moreover, the type of modulation technique used also affects these problems [2]. MSK modulation technique is one of the modulation techniques mostly preferred today in MIMO-OFDM systems, 802.15.4 standard, optical and satellite communication due to its high spectral efficiency [3]- [5].…”

In this paper, we present two novel reformulations (1) and (20) for MSK (Minimum Shift Keying) modulation technique. By using these novel reformulations, we find an additional switching bit, referred to as R-F bit, and propose a novel MSK architecture. Compared to known prior MSK architectures, our architecture offers significant advantages with respect to power consumption and hardware efficiency. Additionally, a pre-computation technique is used to reduce ram bit utilization (RBU) of the proposed modulator. Considering the whole modulation procedure, this approach reduces the RBU of the proposed architecture by 75%. The experimental results show that our architecture is very suitable for MSK modulation.

DALI Bridge FPGA-Based Implementation in a Wireless Sensor Node for IoT Street Lighting Applications

et al. 2020

Smart lighting systems based on the Digital Addressable Lighting Interface (DALI) protocol are the most suitable for street lighting systems, allowing digital lighting control operations. Unfortunately, the microcontrollers, which are commonly used in the Wireless Sensor Network nodes to control the lamps, do not implement this protocol. The DALI protocol implemented by software in the microcontroller consumes hardware resources (timers), processing time and requires a precise temporal analysis of the application, due to the strict bit times and the Manchester coding that it uses. In this work, the design of a bridge is proposed to free the microcontroller from the implementation of the DALI protocol. The novelty of this work is the implementation of the DALI Bridge in a low-cost Field-Programmable Gate Array (FPGA) with low power consumption. The bridge has been described in the hardware description language following the 1076-93 and 1076.3-97 standards, to guarantee its portability. The results of the synthesis show that a minimum amount of logical and routing resources is used, that the power consumption is in the order of tens of mW, that it has a very small latency time and that it supports a high operating frequency, which allows adding new functions. Its operation is verified by implementing a wireless sensor node using an FPGA of the Lattice Semiconductor iCE40 family.
