“…The master FPGA (Red Pitaya) is responsible for receiving orders from PC and control MW source and sampling module (including DAQ and DSP). Except from 3-pin serial peripheral interface (SPI) [ 26 ], the master–slave FPGA is connected by a trigger signal, which could ensure the signal synchronization between signal sampling and microwave generation.…”

In recent years, the nitrogen-vacancy (NV) center in diamonds has been demonstrated to be a high-performance multiphysics sensor, where a lock-in amplifier (LIA) is often adopted to monitor photoluminescence changes around the resonance. It is rather complex when multiple resonant points are utilized to realize a vector or temperature-magnetic joint sensing. In this article, we present a novel scheme to realize multipoint lock-in detection with only a single-channel device. This method is based on a direct digital synthesizer (DDS) and frequency-shift keying (FSK) technique, which is capable of freely hopping frequencies with a maximum of 1.4 GHz bandwidth and encoding an unlimited number of resonant points during the sensing process. We demonstrate this method in experiments and show it would be generally useful in quantum multi-frequency excitation applications, especially in the portable and highly mobile cases.

This work were developed to read and decode a Steering Angle Sensor (SAS) for use information provided by it in future applications. It was made all the bibliographic survey needed by the development of the validation tool. It were shown some concepts about CAN (Controller-Area-Network) Networks, which were used in the connection between the SAS sensor and the validation tool, as well as SPI (Serial Peripheral Interface), the protocol needed to integrate a CAN device and the development board in which were implemented all logics to decode and evaluate data. Using a display, it was programmed an interface for show all the decoded data to user. With the complete development of the validation tool, sensor evaluation were made and it shown satisfactory results after the comparison between the real measurement made by a computational software and the real value.

Serial Peripheral Interface (SPI) is a synchronous serial communication whose data or signal transmission involves Chip Select (CS) or Slave Select (SS) pins, Serial Clock (SCK), Master Out Slave In (MOSI), and Master In Slave Out (MISO). In the Arduino Uno, there are four pins that allow Arduino Uno to perform SPI communication. In this research, SPI communication is implemented to expand the output of the Arduino Uno by using the features of the MCP23S17 IC so that the Arduino Uno, which initially has 20 output pins, can expand to 36 output pins.The results of the research show that the Arduino Uno manages to control 36 output pins. 16 output pins from the MCP23S17, 16 output pins from the Arduino Uno, and 4 pins are used for the SPI communication line. The results of this study also show the form of the SPI communication signal from Arduino Uno in declaring 21 registers on MCP23S17, declaring the MCP23S17 pin register as output, and implementing the output using LEDs.
