Firmware is a form of computer software that provides low-level control over a device’s specific hardware. Firmware can perform all monitoring, control and data manipulation functions as a complete operating system for less complex devices, or as a standard operating system for more complex applications. A few examples of firmware-enabled devices are home appliances, embedded software, computers and their accessories or TV remote controls.
Putting it all together

OSCC software consists of the necessary firmware for all the Arduino boards. Firmware is the embedded software that controls the hardware components. There are also some elements of control software that are designed to work with a standard SDV middleware, such as ROS. The software and firmware is based on PolySync’s Core platform, and full instructions for building and installing are provided on the OSCC wiki. Below, we give an example of how to build the firmware for a petrol Kia Soul. # navigate to the correct directory cd firmware mkdir build cd build # use flags to tell cmake to build for a petrol vehicle and to override operator control cmake .. -DKIA_SOUL=ON -DSTEERING_OVERRIDE=OFF # now build the firmware with make make # alternatively, use make <module-name> to build a specific module make brake make can-gateway make steering make throttle # now you can upload each module. The system expects a single module connected to /dev/ttyACM0 make brake-upload # if you want to upload all the modules at once specify their addresses cmake .. -DKIA_SOUL=ON -DSERIAL_PORT_BRAKE=/dev/ttyACM0 -DSERIAL_PORT_CAN_GATEWAY=/dev/ttyACM1 -DSERIAL_PORT_STEERING=/dev/ttyACM2 -DSERIAL_PORT_THROTTLE=/dev/ttyACM3 # now you can flash all the modules at once make all-upload
Software Quality Management
Published in Jong S. Lim, Quality Management in Engineering, 2019
The definition of firmware by ISO 24765 [ISO 17a] is “combination of a hardware and computer instructions or computer data that reside as read-only software on the hardware device.” In other words, firmware is a computer program, i.e., embedded software in an embedded system that provides smart functions for hardware products. The firmware does not need an operating system like a computer. However, it is able to tell a microcontroller how to work. For example, firmware in the microcontroller of a refrigerator can control complex functions without a computer operating system.
The impact of IoT on manufacturing firm performance: the moderating role of firm-level IoT commitment and expertise

The result shows that IoT implementation (as proxied by IoT adoption) has a negative and insignificant effect on both PBIT and PAT. However, our result is in contrast to the findings of past studies. Scholars have found that only the adoption of digital technologies brings performance benefits for instance, the direct positive effect of cloud computing on economic performance (Schinedejans and Hales 2016), digital technology on economic performance (Li, Dai, and Cui 2020), and data driven supply chain on financial performance (Yu et al. 2018). However, these studies have been based on qualitative reasoning. Our study offers quantitative reasoning to justify the relationship. The reason behind the insignificant negative performance impact is the cost of the functional components and technical complexities of IoT is still a mere burden for firms. Apart from cost, tags, sensors, and actuators IoT systems need an additional mechanism for seamless data transmission. For instance, IoT devices must be connected with the firmware and middleware to interconnect with the physical things and central hub. The network layer comprises a wireless protocol to transfer the data and ensure encryption. The backend infrastructure cloud server facilitates the aggregation, storage, and process of sensor data. The collection of quality data from the layered network architecture and advanced analysis depends on the utilisation of organisational readiness and technical expertise and TMT support (Cranmer et al. 2022).
