A brief intro to capacitive touch and MSP’s capacitive touch solutions
Though Static RAMs and Ferro-Electric RAMs (F-RAM™) can have quite different purposes, with the advent of standard interfaces such as SPI, these technologies have large overlap in their capabilities. This white paper details the common attributes of SRAM and F-RAM, which provided the primary motivation for the replacement of serial SRAM in the design. Considerations that need to be made in the replacement of SRAM with F-RAM are detailed. This document also provides the analysis required to make certain there are no issues. Finally, the paper describes the advantages of migrating to F-RAM, which directly result in customer-visible benefits.
Some decades ago, the embedded industry shifted focus from assembly to C programming. Faster processors and better compilers allowed for raising the level of abstraction in order to improve development productivity and quality. We are now in the middle of a new major shift in firmware development technology. The increasing use of real-time operating systems (RTOS) represents the third generation of embedded software development. By using an RTOS, you introduce a new abstraction level that enables more complex applications, but not without complications.

With the increasing deployment of automated technical solutions in the implementation of automated metering reading (AMR), advanced metering infrastructure (AMI) and smart grid infrastructure, possibilities of security attacks like data hacking, introducing malware in the system and cyber attacks are on the rise as well. Vulnerabilities in AMI devices include non-secure data buses, serial connections or remote access to debug port. The question arises: how can data security and customer privacy in smart meters and smart energy gateways be ensured? This paper talks about how trusted computing helps resolve security issues in implementing the smart grid by providing a clear idea of what elements of the system are trusted—and to what level and why. Freescale solutions that embed trusted computing are also covered.
This whitepaper is for developers new to TI ARM®- based processors, as well as for experienced developers wanting to better understand the various ARM architectures. Beginning with an overview of ARM technology and available processor platforms, this paper will then explore the fundamentals of embedded design that influence a system’s architecture and, consequently, impact processor selection. However, selecting the right processor involves more than just estimating performance requirements. Software often represents a majority of the development investment, both in terms of cost and time, and so the optimal processor for an application also has the right development resources supporting it. Finally, an application-specific perspective is required to determine how the needs of particular markets also affect processor and software requirements. After reading this whitepaper, developers will be able to identify an appropriate ARM processor for their current application, as well as which development resources they need to immediately begin processor evaluation and design.
There are several dimensions to the scalability of general-purpose microcontrollers (MCUs). In addition to the standard peripherals required, a product family will typically offer developers a range of device options across processor speed, memory, GPIO pins, and packaging. With the increasing need for connectivity driven by the Internet of Things (IoT), a new dimension of scalability is required: wireless connectivity technology.
Rising data communication rates are driving the need for very high-bandwidth real-time oscilloscopes in the range of 60-70 GHz.

New uses continue to emerge; for example, you might be able imagine a design for a thermostat using a display powered by gesture recognition or interactive touch.

Next-generation industrial, vision, medical and other systems seek to combine highend graphics and rich user interfaces with hard real-time performance, prioritization and precision.Today’s industrial PCs running 64-bit Windows, complemented by a separate scheduler on multicore multiprocessors, can deliver that precise real-time performance on software-defined peripherals.
The Internet of Things (IoT) is no longer a fanciful vision. It is very much with us, in everything from factory automation to on-demand entertainment. Yet by most accounts, the full potential of interconnected systems and intelligent devices for changing the way we work and live has barely been tapped. Up until now, IoT software solutions have largely had to be built from scratch with a high degree of customization to specific requirements, which has driven up the cost and complexity of development and deterred many prospective entrants to the market. What have been missing are developer tools that alleviate the costs associated with building the foundational infrastructure—the “plumbing” of their solutions—so they can focus on optimizing the core functionality and bring solutions to market more quickly with less cost. Wind River® is addressing these challenges with new solutions that have the potential to expand the market for IoT by reducing the cost and complexity of development. This document outlines the challenges that IoT poses for developers, and how Wind River solutions can help overcome them.
The low-noise system architecture and the tailored frequency response employed in the HDO4000A, HDO6000A, HDO8000A and MDA800A series provides the foundation for enhancing ADC sample rates through additional techniques. In this case, carefully constructed filters combined with a pristine front-end amplifier and a frequency response carefully limited to 1 GHz provide the opportunity to provide more measurement precision than would otherwise be possible. The technique utilized to achieve higher measurement precision is interpolation, and this technique is used by default as an Enhanced Sample Rate up to 10 GS/s. By integrating the Enhanced Sample Rate functionality with the normal Timebase controls for Sample Rate, Time and Acquisition Memory adjustment, the oscilloscopes are optimized for best waveform signal fidelity in all situations.
Capacitive touch as a human-machine interface (HMI) technology is finding its way into more and more applications each year. It is rapidly becoming a popular technology for mechanical button replacement in end equipment such as small and large home appliances, industrial control panels and automotive center stacks. While the technology offers designers new freedoms in how they can differentiate their products via the user interface, it also presents new challenges. The challenges arise from the fact that these markets often share two important characteristics: they are high in electrical noise and they have safety-critical functions controlled by the user interface.
The high-definition multimedia interface (HDMI) standard is the leading standard for the transmission of uncompressed video data within the home. To ensure that all devices using this interface work together seamlessly, the HDMI Forum has defined and compiled a series of tests in a Compliance Test Specification (CTS). These include protocol tests as well as tests of the electrical parameters for an HDMI interface. Because of the technology used for HDMI and the associated high data rates, these tests require complex and cost-intensive T&M equipment. This paper describes an efficient alternative in the form of a sampling oscilloscope. It covers the fundamental principle behind electrical testing of HDMI sources, such as those found in set-top boxes, Blue-ray players, cameras, PCs and smartphones. It additionally discusses the differences as compared to the conventional time-domain analysis methods.

We’re entering a new era of computing technology that many are calling the Internet of Things (IoT). Machine to machine, machine to infrastructure, machine to environment, the Internet of Everything, the Internet of Intelligent Things, intelligent systems—call it what you want, but it’s happening, and its potential is huge. We see the IoT as billions of smart, connected “things” (a sort of “universal global neural network” in the cloud) that will encompass every aspect of our lives, and its foundation is the intelligence that embedded processing provides. The IoT is comprised of smart machines interacting and communicating with other machines, objects, environments and infrastructures. As a result, huge volumes of data are being generated, and that data is being processed into useful actions that can “command and control” things to make our lives much easier and safer—and to reduce our impact on the environment. The creativity of this new era is boundless, with amazing potential to improve our lives. What does the IoT need to become a reality? In this white paper, Freescale and ARM partner to answer that question.
