The IEEE 802.15.4 standard is the fourth task group of the IEEE 802.15 working group, which defines Wireless Personal Area Network (WPAN) standards. The IEEE 802.15.4 market has the following advantages; low power consumption, low cost, low offered message throughput, supports large network orders up to 65k nodes, low to no QoS guarantees, and flexible protocol design suitable for many applications. The purpose for this standard is to empower simple devices with a reliable, robust wireless technology that could last for years on standard primary batteries. It is designed to allow developers to effectively use and benefit from radios based upon the standard.

This reference design is a low cost System-on-Chip (SoC) solution for the IEEE 802.15.4 standard that incorporates a complete, low power, 2.4GHz radio frequency transceiver with TX/RX switch, an 8-bit HCS08 CPU, and a functional set of MCU peripherals into a 48-pin LGA package. This product targets wireless RF remote control and other cost-sensitive applications ranging from home TV and entertainment systems to medical and supports all ZigBee node types. The Freescale’s MC13237 is a highly integrated solution, with very low power consumption. The MC13237 contains an RF transceiver that is an 802.15.4 standard 2006 compliant radio that operates in the 2.4GHz ISM frequency band. The transceiver includes a low noise amplifier, 1mW nominal output Power Amplifier (PA), internal Voltage Controlled Oscillator (VCO), integrated transmit/receive switch, on-board power supply regulation, 12-bit ADC and full spread-spectrum encoding and decoding.

This design is not only limited for remote controls. It can also be used as the basis for wireless devices and other sensor-controlled application that used IEEE 802.15.4 standard. The IEEE 802.15.4 radios have the potential to be the cost-effective communications backbone for simple sensory mesh networks that can effectively carry data with relatively low latency, high accuracy, and the ability to survive for a very long time on small primary batteries.

MC33814AE

An industrial plant is designed with different control systems in which it varies according to the equipment to be controlled. This design is a general-purpose engine control system, which handles fueled or electrically supplied small engines of industrial plant. It features a 1.0A power relay control, 2.0A relay for fuel pump control, and a lamp driver. The system is also capable of start-up/shut-down control with power sequence logic. It has independent fault protection against surges and possible fluctuations.

The design is comprised of a MC33814 engine control analog power IC, a USB to SPI dongle interface, and power conditioning circuitry. It drives the engine electrically or fueled through relays. It also drives the fuel injector that runs the equipment during fueled operation. All 5V VCC power required by the circuit is obtained from the MC33814 built-in power regulator. A 12V VBAT supply provides the power to the three internal voltage regulators. A PC communicates to this project through a USB/SPI dongle (KITUSBSPIDGLEVME) connected to the PC’s USB port. The Freescale SPIGen program provides the user interface to the MC33814 SPI port and allows the user to send commands to the IC and receive status from the IC.

This project is designed to drive several industrial engine functions, a set of screw terminals are designated for control outputs: tachometer output, lamp output, water heater output, two relay outputs, two injector outputs, and two ignition outputs. This kind of control system is very useful in machineries that are usually used in industrial plants for the convenience of the plant operators.

Freescale have introduced a new range of 3-axis accelerometers offering high sensitivity at low power consumption. According to Freescale the FXLN83xxQ family is capable of detecting acceleration information often missed by less accurate sensors commonly used in consumer products such as smartphones and exercise activity monitors. In conjunction with appropriate software algorithms its improved sensitivity allows the new sensor to be used for equipment fault prognostication (for predictive maintenance), condition monitoring and medical tamper detection applications.

There is cool contest for EEs, with actual prizes running right now.  EEWeb.com is running the “2014 European Design Freedom Contest”  (at http://www.eeweb.com/freedomcontest) and the prizes include iPads and iPods as well as a football table, espresso machine, or bike.  You’ll get to design projects using the Freescale Freedom Kinetis ARM based development platform.

The contest uses free online tools from Digi-Key.  The first part of the contest uses Scheme-It for you to generate a block diagram of your contest entry that uses one of the 10 available Freescale Freedom Platforms; the project can be a solution to a real problem or something novel.  This first phase of the contest runs through the end of June.

In the second phase, create a PCB design of your project.  You can also go with a software submission using ARM mbed studio online software (mbed.org).  The 2nd phase runs through Oct 10th.

Freescale Freedom Boards are a series of ultra-low-cost development platforms featuring the Kinetis family of MCUs based on the ARM Cortex M Series Cores. The boards are compact In a size a little bit bigger than a credit card. It can provide easy access to the MCU I/O pins, low-power operation and an open standard embedded serial and debug adapter (Open SDA).  Other added features include two USB Mini-B type connectors where one is labeled K20 that acts as a USB host and the other is labeled SDA for a built-in debug interface for flash programming and run-control.

In the video is the K20D50M Evaluation Board that comprises a K20 Processor based on the ARM Cortex-M4 processor. Some other features of the board include an accelerometer, ambient light sensor, RGB LED and a capacitive touch slider.  K20D50M I/O pins are also routed out in such a way that it is compatible with Arduino Shields, a third-party expansion board. This also means that K20D50M can be supported by a range of Freescale and third-party development software. Read the rest of this entry »

Do you want to many processors on one board? Check this out. UDOO is an open hardware, low-cost computer equipped with an ARM i.MX6 Freescale processor for Android and Linux, alongside Arduino DUE’s ARM SAM3X, both CPU integrated on the same board! UDOO takes your DIY projects to the next level and it’s a powerful tool for education and creativity. UDOO could run either Android or Linux, with an Arduino-compatible board embedded.

We are delighted to announce a new mini-Pc board, UDOO, which integrates two processors, ARM i.MX6 by Freescale (for Android & Linux) and ARM SAM3X of Arduino DUE in a single board measuring 4.33 inch x 3.35 inch (11cm x 8.5cm).

On April 9th we launched a Kickstarter campaign which already reached the target of $27,000 in barely 2 days and keeps growing having raised 1700% over its target.

UDOO was conceived to both expedite the rapid prototyping of professional solutions and to support teaching activities in the field of physical computing, internet of things and interaction design. With the goal of promoting the use of the board in these domains we have built an international network of 5 universities: Carnegie Mellon University, USA; Aarhus University, DK; Siena, IT; OCADU Toronto CA;  University of California San Diego, USA in order to share teaching experiences and to present solutions to create an open community accessible to everyone.

To learn more about UDOO, and to support our project, please visit kickstarter following http://kck.st/XBthCV and check out our website http://www.udoo.org/ to stay up to date with newsabout UDOO.

The Kinetis L Microcontroller board from Freescale. The board features a Cortex-M0+ ARM processor, a suspiciously familiar minty-fresh board silhouette, and headers that remind me of summers in Ivrea. From EDA360: [via]

There are two major reasons for reading this blog post:
A 32-bit microcontroller that sells for as little as $0.49 in 10K quantities and consumes 50µA/MHz
A $12.95 development board to be available late in September

These are two of the salient attributes of the Freescale Kinetis L microcontroller, previewed at Design West in San Jose back in March and now announced at the Freescale Technology Forum in San Antonia with alpha samples shipping. The target for this product is the vast sea of products and applications that currently incorporate 8- and 16-bit microcontrollers—mainly for reasons of legacy code, legacy familiarity, and cost. It will take a compelling product to hurdle these barriers and the low prices for the Kinetis L silicon and development board will help to jump those hurdles.
