With the Bolymin BE635 graphic embedded module it´s possible to focus only on software development – hardware is done.

A possibility to interactively adjust various parameters and at the same time to see a “result” of our settings (for example a status of a given device) considerably increases safety and reliability in various industry sectors. That´s probably one of reasons why a graphic output becomes a standard even in devices, where they were recently used very rarely so far.

From the development point of view, one of the key deciding factors is a platform, on which a given system is built (processor, OS).
PIC32 family certainly belongs to popular microcontrollers (32 bit RISC CPU), that´s why the new graphic embedded module Bolymin BE635 addresses all, who know PIC32, or they want to become familiar with it. For everyone, who´ve ever worked with PIC32 family, a development of application will be much easier with BE635, as practically all necessary hardware is on one board and at the same time we get a support in a form of various drivers for communication as well as graphic output. For programming purposes a new Microchip PICkit3 is suitable and SW development can be done in the known environment Microchip MPLAB IDE. BE635 is designed as a universal module, where only a designer decides, how much computing power of a processor will use on which activity (displaying, data processing, external HW control, communication, …), that´s why possibilities of its usage are really very wide.

Compact module (93x67x15mm) with a 3,5“ TFT LCD display (320x240px) is equipped sufficiently, to become attractive. For example:

  • built-in 512kB ISP flash/ 64 kB SRAM/ 16 kB EEPROM
  • support of microSD
  • 1x RS232, 1x SPI, 1x I2C
  • selectable 1x RS232/422/485/USB (depending on a version)
  • 1x 10bit ADC, 12x GPIO
  • libraries for successful programming, drivers for interfaces and a touch panel

BE635 is available in 4 versions, differing by an additional RS232/485/422/USB port. Single supply 5V and easy mechanical assembly by means of a metal frame with mounting holes also belong to pluses of a new BE635. Soon, there will be available also other similar modules with the same functionality but with bigger displays, for example BE657 with a 5,7“ (640x480px) display, thus an application for BE635 will be usable for the BE657 alike.

Detailed information can be found in BE635, BE657 flyers and in the BE635 user manual .

Three physicists have been awarded the Nobel Prize for revolutionizing the way the world is lighted.

The 2014 physics award went to Isamu Akasaki and Hiroshi Amano of Japan and Shuji Nakamura of the University of California, Santa Barbara, for “the invention of efficient blue light-emitting diodes, which has enabled bright and energy-saving white light sources.”

The three scientists, working together and separately, found a way to produce blue light beams from semiconductors in the early 1990s. Others had produced red and green diodes, but without blue diodes, white light could not be produced, the Royal Swedish Academy of Sciences said on Tuesday morning in its prize citation.

Technology from a Taiwanese semiconductor foundry is to bring considerable benefits in performance and power efficiency to big.LITTLE implementations, in the name of FinFET. Hsinchu, Taiwan-based TSMC announced last month it had successfully produced the first fully functional ARM-based networking processor with FinFET technology and explained how TSMC’s 16FinFET process promises speed and power improvements as well as leakage reduction.

MP23AB02B

by Graham Prophet @ edn.com:

STMicroelectronics’ MP23AB02B MEMS microphone maintains ultra-low distortion at less than 10% up to very high external sound-pressure levels, enabling equipment such as smartphones and wearable devices to perform better when placing calls or recording audio in loud environments.

With acoustic overload level of 125 dB SPL and signal-to-noise ratio of 64 dBA, the 3.35 x 2.5 x 0.98-mm microphone employes ST’s dedicated preamplifier design, which prevents saturation of the output signal even when background-noise levels are high, such as in concert venues, bars or clubs, or if the user is speaking loudly close to the microphone. In addition, omnidirectional sensitivity ensures overall performance and versatility in mobile applications.

Whether we care to admit it or not, motors can be found all over in our everyday lives; they just tend to be hidden. Motors are present in cars, printers, computers, washing machines, electric razors, and much more.

However, there are a number of people (which until recently included myself) that would be uncertain of how to make a motor run if they were handed one. So, let’s learn something today. Let’s learn how to use a stepper motor!

MAX9632

This compact Fremont subsystem reference design accurately measures low voltage, 0 to 100mV, single-ended analog signals with a high-accuracy, 16-bit analog front end (AFE) complete with an isolated data path. The design optimizes the functions of an ultra-precision low-noise buffer (MAX9632); a highly accurate ADC(MAX11100); an ultra-high-precision 4.096V voltage reference (MAX6126); a 600VRMS monolithic data isolator (MAX14850); and low-dropout (LDO) regulators providing regulated +6V, +5V, and -5V power rails (MAX1659 and MAX1735).This one-of-a-kind AFE solution works in many applications requiring low-voltage input, high impedance, and high-accuracy analog-to-digital conversion.

I’m continuing working with Juan Brito and Danny Macancela from the blog Desafio Ecuador, developing new boards to bring near the technology and programming languages. Our last work is a board to use with the Raspberry Pi and focused to learn Python. The board has the basic elements to start with this language. Also, with the develop of the PCB we remove the wiring, avoiding troubles with connections, inversion polarity…So with this board you only focused in the software develop, because the hardware side will work!

The LTC2946 is a high or low side charge, power and energy monitor for DC supply rails in the 0V to 100V range. An integrated ±0.4% accurate, 12-bit ADC and external precision time base (crystal or clock) enables measurement accuracy better than ±0.6% for current and charge, and ±1% for power and energy. A ±5% accurate internal time base substitutes in the absence of an external one. All digital readings, including minimums and maximums of voltage, current and power, are stored in registers accessible by an I²C/SMBus interface. The part’s wide operating range makes it ideal for monitoring board energy consumption in blade servers, telecom, solar and industrial equipment, and advanced mezzanine cards (AMC).

by Steve Taranovich @ edn.com:

A circuit or system designer’s job is a difficult one. Fraught with design compromises to be made and challenges to overcome that are sometimes seemingly insurmountable. That’s why our personalities are programmed to solve problems and “Think outside the box”. The best designers don’t even know there is a box!

I see so many new product offerings every day that “fill a hole in our line” or are simply another op amp or regulator for the portfolio among a sea of analog and power devices out there. I turn away the great majority of these so-called “new” products because my readers need innovative solutions with options that can meet their many and varied design needs. Time to market is the mantra in the industry.
