Optimized for motor control and smart sensing applications, Analog Devices ADuC7128 microcontroller (MCU) integrates a 32-bit ARM7 RISC processor with high-speed, multi-channel data conversion, and 126 kbytes Flash memory. The unit's 12-bit multi-channel, analog-to-digital converter (ADC) operates at speeds to 1 MSPS (mega-samples-per-second). Motor control specific peripherals include six-channel pulse-width modulation (PWM) with H-bridge mode. An on-chip quadrature encoder provides the speed, position, and direction control required by dc motor controls. In addition, the ADuC7128 has an integrated direct digital synthesizer (DDS), and I/V control making it applicable to a variety of motor control applications. Packaged in a 9 × 9 mm 64-LFCSP (lead-frame chip-scale package), the device is specified over an operating temperature range of -40 to +85C.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
