NXP Semiconductors - Microcontrollers
NXP's ARM solutions from a basic microcontroller, a more advanced Digital Signal Controller (DSC), or a dedicated application processor. Types Cortex Set, ARM7, and ARM9.
KNX - Solutions for Home & Building Control Applications
The stability and flexibility of KNX make it a tremendously popular choice for intelligent wired home and building automation networks. This evaluation board will help developers create cost-efficient KNX designs very quickly, while taking advantage of the very low active power consumption of the NXP Cortex-M0 microcontroller, as well as its powerful 32-bit architecture.
NXP (for Next eXPerience) Semiconductors is the name for the semiconductor company founded by Philips.

Arduino Open-source Electronics Prototyping
The Arduino Uno is a microcontroller board based on the ATmega328 (datasheet). It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button.
It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.
The Ethernet differs from other boards in that it does not have an onboard USB-to-serial driver chip, but has a Wiznet Ethernet interface. This is the same interface found on the Ethernet shield.

When you look at the History of Operating Systems, you will see that that an OS that meant serious business was UNIX. It was the anvil for the creation of the C Language and AWK. Now we have Linux, the evolved Unix like OS, which is comfortable and versatile for Networking and Clustering.
Embedded Linux Wiki for the embedded product design community.
Gadgets and Appliances are become increasingly complex. More memory and CPU power for small devices are commonplace. Linux is one OS that can be muntzed to the smallest size. This helps developers make something like a super-firmware. Just what you need for that device, can be the OS.
Touchscreens for Home Appliances, wireless networking and web enabled consumer electronics make Linux an excellent escalation from "Firmware". For tiny systems a firmware is the OS. For complex devices today, Linux is user configured firmware.

Measure: Voltage, Freq, Time - and also - Run/Stop data acquisition
OsciPrime - Android Oscilloscope and Data Acquisition
The hardware consists of two parts: the analogue front-end where a signal is tapped and adjusted for the A/D conerters and a digital front-end where the data is quantified and prepared for USB transmission. Key components are a Xilinx Coolrunner CPLD and a Cypress FX2 microcontroller.
Using USB, the hardware plugs into Android devices that support USB Host. Together with the OsciPrime Android oscilloscope application it turns a tablet or mobile phone into a high speed data acquisition system.
- 2x Analogue Input @ 8bit/6Msps
- 5 analogue gain levels
- 3.3 MHz - 8.0 MHz Bandwidth (gain dependant)
- Range +/- 1.5 V up to +/- 16 V
- 5 us/Div max - 1 ms/Div min
- V-Offset, Time-Offset, Calibration
- Trigger Falling/Rising Edge, CH1/CH2

Transistor-Based Variable Current Drive for LED Calculator
"The idea is to expand on a simple LED tester by allowing the user to plug in an LED, dial in the LED brightness, and then read information on an LCD showing the LED voltage drop, the current current, and the value of current-limiting resistor to use in a target circuit. "

Vault Information Services LLC
In October 1985, VIS founder Craig Steiner started a Bulletin Board System (BBS) in Denver, Colorado called "The Vault." This BBS was operated using an Atari 8-bit computer and was an important and innovative system in the Denver BBS scene at the time--especially in the Atari sector. Many features and additions were made throughout the life of the Atari-version of the BBS that kept The Vault on the cutting edge in Denver.

VirtualBreadboard(VBB) is for designing and testing embedded software in high-level interactive circuit simulations and rapidly prototyping hardware from those designs.
Compared to other simulators many people find the high level approach taken VBB easier to use and much faster to model and test out new ideas and circuit variations.
|From Design Gopher - Electronic Product Development|
VBB electronic circuit components are modeled at the function block level and are wired together to create a real-time interactive circuit simulation representing the whole embedded application.
VBB does not use SPICE. SPICE is better suited to subcircuit designs whereas VBB is concerned with merging multiple subcircuits treating each subcircuit as a self contained function block.

Touch Screen Interface - Eurek
EK 280 EK280 is a Linux touch screen designed and optimized for being used on machines and industrial applications. It is based on i.MX27L 400 MHz and Linux 2.6 (Qt 4.6, SDL, FLTK/Nano-x, SQLite) Freescale processor. Thanks to a resolution of 800×480 pixels and a 7’’screen is suitable to create graphical user interfaces (GUI) for all kinds of sophisticated automation.
EK280 is a compact and thin module, provided with a plastic base and spacers to be easily mounted behind a panel using only 4 screws. The touch-screen is resistive, and is operable even with gloves; it can be superimposed by an adhesive film for a perfect aesthetic finish and to make the panel washable.
