Marcus Linderoth built a clock using a TI MSP430g2553 microcontroller and a HPDL-1414 display, that is available at Github:
After having ported Contiki to the Launchpad, I was eager on doing something with it. I built this simple clock with a vintage HPDL-1414 “smart four-character 16-segment alphanumeric” display and a msp430g2553.

With Texas Instruments’ WEBENCH Schematic Editor, engineers can customize power-management designs and simulate the circuit created within the WEBENCH environment. According to the company, the new feature reduces design and verification time from hours to minutes. The editing and simulation package maintains a library of over 40,000 components. As a result, it’s possible to incorporate multiple mixed output capacitors, filtering, board parasitics, and snubber circuits into WEBENCH power-supply designs. Then those customized power designs can be simulated (using the WEBENCH Power Designer’s Spice simulator) before they’re exported to CAD development platforms like Cadence OrCAD Capture CIS, Mentor Graphics Xpedition xDX Designer, CADSoft EAGLE, and Altium formats (e.g., Altium Designer). The WEBENCH environment consists of online tools such as Designer and Architect that enable end-to-end analog circuit design.

Texas Instruments unveiled a new Tilt & Roll Pixel (TRP) DLP pico chipset. According to TI, this is the smallest (at 0.3″, which is strange because the previous model was 0.2″) and most efficient DLP chip ever. It support HD resolutions (probably 720p) and can be used in pico projectors and wearable displays, augmented reality displays and other applications. [via]
The new Texas Instruments 0.3″ HD Tilt & Roll Pixel (TRP) DLP® Pico™ chipset is TI’s smallest, most power-efficient HD micro-mirror array and can generate 720p displays from compact applications, including tablets, smartphones, accessories, wearable displays, augmented reality displays, interactive surface computing, digital signage and control panels. The chipset delivers significantly higher levels of brightness and power efficiency, allowing developers to create a wide variety of applications and products in smaller form factors than ever before. The chipset’s fast switching speeds of up to thousands of times per second enable the world’s smallest true color RGB engines with 120Hz video performance.

Over a week ago I’ve got a notice that Texas Instruments (TI) is giving away a 50% coupon for MSP430_FRAM related devices. Without hesitation ordered their MSP-EXP430FR5739 TI experimenters board that price went down to $14.50 including free shipping.
MSP EXP430FR5739 FRAM based microcontroller board is interesting piece of hardware. It features FRAM memory instead of Flash which is claimed to withstand almost unlimited number of Reads and Writes. It is also faster. It can substitute an EEPROM on board. But it is not very popular technology due to different manufacturing. On this development board there is MSP430 microcontroller which has 16KB FRAM, 1KB of SRAM. It carries eight LEDS, MTC thermistor, 3 axis digital accelerometer, optional LDR, couple buttons. So this is great for many uses.

Active analog filters can be found in almost every electronic circuit. Audio systems use filters for frequency-band limiting and equalization. Designers of communication systems use filters for tuning specific frequencies and eliminating others. To attenuate high-frequency signals, every data acquisition system has either an anti-aliasing (low-pass) filter before the analog-to-digital converter (ADC) or an anti-imaging (low-pass) filter after the digital-to-analog converter (DAC). This analog filtering can also remove higher-frequency noise superimposed on the signal before it reaches the ADC or after it leaves the DAC. If an input signal to an ADC is beyond half of the converter’s sampling frequency, the magnitude of that signal is converted reliably; but the frequency is modified as it aliases back into the digital output.

Texas Instruments is one of the most dominant technology companies ever. Behind Intel and Samsung, it is the world’s third largest producer of semiconductors. In addition, they are the largest manufacturer of digital signal processors and analog semiconductors. Young students may just know of TI as producers of their world famous graphing calculators. However, for the older, more experienced students, they quickly learn TI has technology that can be found everywhere. In fact, many of the ICs used for basic electronics are all created by TI.
There is also one additional area TI’s technology excels at. That would be in energy efficient electronics. One of the more popular devices is the MSP 430 microcontroller family. These MCUs allow developers to create embedded applications, which can manage power extremely efficient. The CPU can work with speeds up to 25 MHz or can be lowered to save power in applications. More importantly, the MCU has a low power idle mode. When working in this mode the CPU will draw as little as 1 micro-Amp of current. Along with the low power capabilities, this MCU can also work with all the usual embedded electronics communication protocols and peripherals.

Texas Instruments Incorporated is offering developers a solution to the challenges posed by the Internet of Things (IoT) revolution with the company’s introduction of the SimpleLink Wi-Fi CC3000 module.
The IoT enables devices to be wirelessly connected to the home network and to the cloud. However, headless devices with no keypads or touchscreens including garage door openers, home appliances, lights, thermostats and treadmills can be complicated to connect to a Wi-Fi network.
The self-contained SimpleLink Wi-Fi CC3000 module features the SmartConfig technology, a Wi-Fi configuration process developed by TI that allows multiple in-home devices without displays to connect to a Wi-Fi network via a smartphone or tablet – in just one easy step.

Texas Instruments has developed a new, free real-time operating system (RTOS) based on a pre-emptive multithreading kernel, which will run on the full portfolio of TI microcontrollers, including dual core devices. TI-RTOS includes a deterministic, real-time multitasking kernel (SYS/BIOS) with a TCP/IP stack, including network applications, USB, EMAC, MMC/SD host and device stacks and class drivers, FAT-compatible file system fully integrated with C RTS file I/O functions and Ethernet, USB, UART, I²C and SD device drivers. It also supports low overhead core-to-core communication mechanism for dual-core devices. [via]

element14 has teamed up with top suppliers, including Texas Instruments, Wurth Elektroniks and Cadsoft, to launch a new wireless power microsite. Designed to accelerate the integration of wireless power solutions in popular applications, such as smart phones, digital cameras and more, the site gives engineers access to a wide range of technical experts, complimentary webinars, product roadtests, and safety and compliance standards.
Engineers are invited to learn more by registering for a free webinar – “Charging Innovation – Cut the Cord” – on Thursday, Sept. 20 at 3 p.m. GMT/9 a.m. CDT. Attendees will see a demo of the new microsite, an overview of wireless power reference designs, and an opportunity to have questions answered during a live Q&A session following the webinar.
