Abstract

Purpose

Aims to design a heterogeneous embedded system with CPLD and microcontroller as co‐processors sharing a memory module.

Design/methodology/approach

The system receives external analog input signal, which is applied to the PIC 16F73 microcontroller. Upon converting the data in to digital format using the on‐chip ADC, the PIC stores the digitized version in the SRAM (HCM 6264) chip. SRAM HCM 6264 has been used as a shared memory model, of which both the PIC and CPLD can access all the locations. Once the PIC passes controls to the CPLD, the further processing is carried out by the CPLD without any intervention of the PIC. This is a true example of co‐processing of the architecturally diversified computing modules from completely different vendors with totally different programming suits.

Findings

The board has been tested with IC temperature sensors and also found to be useful for sensor array applications involving three types of processing viz. analog (through instrumentation amplifier), real‐time digital (through microcontroller) and customized reconfigurable digital (with the CPLD).

Practical implications

The system has several potential applications in avionics, military and robotic embedded systems, which have inherent real‐time constraints that need to be supported by the underlying hardware and driver programs.

Originality/value

Discusses the rare and unique combination of diversified processing core to build an embedded system.

Abstract

In this chapter, an attempt has been made to develop a security-based hardware system using an 8-bit single-chip microcontroller in conjunction with some sensor technology and lighting and alarming actuators. The proposed system aims to ensure the security and privacy of a dedicated area in terms of unauthorized human intrusion, hazardous gas leakage, extreme prolonged temperature changes, atypical smoke or vapor content in space and abrupt drop in illumination. The proposed system is capable of detecting any type of physical intervention and hazardous anomalies in the environment of the reserved space. In order to define the operation of the system, programs written in C++ with the special rule of code structuring have been deployed on the microcontroller using the Arduino Integrated Development Environment. The system is like a small container, enclosing all the respective sensor modules, microcontroller board and open connections for actuators. The proposed system is easy to use hardware and does not demand any human intervention for its functioning and can be installed with almost no changes in the infrastructure.

Abstract

Purpose

The purpose of this paper is to describe an approach towards code validation of RISC microcontrollers, which helps to automate software debugging. A static machine code analysis which checks the appropriateness of instructions in a sequence to identify any logical mistakes and also to identify redundant codes appearing in a program for the target processor is presented.

Design/methodology/approach

Validation is done with the help of rules of inferences formulated for the target processor. The rules govern the occurrence of illegitimate/out of place instructions and code sequences for executing the computational and integrated peripheral functions. The stipulated rules are encoded in propositional logic formulae and their compliance is tested in all possible execution paths of the application programs. An incorrect sequence of machine code pattern is identified using slicing techniques on the control flow graph generated from machine code.

Findings

The results explain that the technique is independent of compiler/assembler and contributes to early detection of software bugs that are otherwise hard to detect. Program states are identified mainly with machine code pattern, which drastically reduces the state space creation contributing to an improved state‐of‐the‐art model checking.

Research limitations/implications

Though the technique described is general, the implementation is highly architecture oriented, and hence the feasibility study is conducted only on PIC16F87X microcontrollers.

Practical implications

This validation tool can be integrated to the system development environment resulting in improved software quality and reduced debugging time.

Originality/value

It is a novel and original approach at machine code level applicable to a wide range of processors once appropriate rules are available.

Abstract

Purpose

In the capricious span of this current millennium, there is a deafening roar in the demand for modernization in the sector of robotics and technology to perform tasks in an intelligent manner. Thus to replenish such necessities, the innovations and inventions of researchers came forward as blessings on human civilization due to their sheer ingenuity and relentless and arduous efforts with each nanosecond passed from now onwards. With the same sublime goal, same resilient endeavor, same aggressive demeanor, the paper on obstacle avoiding robots comes forward. The paper aims to discuss these issues.

Design/methodology/approach

It exhibits how to control a differential drive robot wirelessly by analog thumb joystick module with added obstacle avoidance protection. The variations made by the user in the control of analog thumb joystick module are fed as input to the Atmega 16 microcontroller board which further transfers it wirelessly to the robot through the radio frequency (RF) transmitting module. The Arduino mega microcontroller equipped to the robot cross-checks the instructions gained through the RF receiving module and provides power accordingly to the geared motors through the motor driver board for movement along with scanning the environment to avoid obstacles present thereby.

Findings

The improvisation of RF technology in controlling the obstacle avoiding robot has enhanced its application and reliability by leaps and bounds reducing the anxiety and tension of the human controller.

Originality/value

With more advanced algorithm and genuine deployment sensors, the idea behind this research work can be used in humanoid robots which can help immensely in going to the extremely dangerous terrains, war zones and also in human rescue operations.

Abstract

Purpose – The purpose of this research is to design and build a wild animal pest repellent device with combination of passive infrared (PIR) sensor and ultrasonic signal based on microcontroller as system controller. The PIR sensor is used to detect the presence of wild animal objects and ultrasonic signals to interfere with the hearing.

Design/Methodology/Approach – The design of the system is built based on microcontroller as the system controller. The system as a whole includes hardware and software. The design of hardware consists of the system design on the transmitter side and the system design on the receiver side, while the software in the of system are algorithms using C language programming.

Findings – The resulting repellent device can detect animals approaching up to a distance of 5 m and may interfere with its hearing with a 40 kHz ultrasonic frequency up to a distance of 20 m. The system also uses remote monitoring devices using 433 MHz radio frequency up to a distance of 60 m.

Research Limitations/Implications – Each animal has different hearing frequencies, as well as some wild animals, but the hearing frequencies of wild animals are generally at ultrasonic frequencies. The frequency of animal hearing may vary from audio frequency to ultrasonic frequency, so ultrasonic wave emission testing with varying frequencies is required.

Practical Implications – This research combines systems on transmitters and receivers, with real-time monitoring of wild animal positions, and it can be possible to monitor the position of more detailed animals by installing more types of sensors as well as increasing the number of sensors.

Originality/Value – This paper may provide additional insight into the hearing frequencies of animals and may also serve as comparable papers for similar studies.

Abstract

This chapter presents the Smart Irrigation system using the Internet of Things (IoT). IoT Technology is a network of physical objects that are connected with sensors, software, etc. This chapter concludes the project based on the agriculture field that automates the irrigation process and on the agriculture field that automates the irrigation process and solves the challenge of water consumption in those areas. We have developed the system using different sensors like (1) Soil Moisture sensor, which measures the moisture present in the soil, (2) Humidity and Temperature Sensor (DHT11), which traces the temperature change. All these sensors are connected to the Node MCU ESP8266 microcontroller, which is also a Wi-Fi module. It uploads the data to the cloud and displays it in the form of readings detected by the Blynk Application. This sensor's reading values control the pump for emergency purposes, such as stopping the pump for irrigation. Thus, this project can automate the irrigation process by analyzing soil moisture and climatic conditions, covering essential aspects like less labor, power consumption, reliability, and cost.
