Linduino

Linduino is Linear Technology’s Arduino compatible system for developing and distributing firmware libraries and example code for Linear Technology’s integrated circuits. The code is designed to be highly portable to other microcontroller platforms, and is written in C using as few processor specific functions as possible. The code libraries can be downloaded by clicking the Downloads tab above and used as-is in your project or individual code snippets may be viewed in the Code section of a supported part. The Linduino One board (Demonstration Circuit DC2026) allows you to test out the code directly, using the standard demo board for the particular IC.

The Linduino One board is compatible with the Arduino Uno, using the Atmel ATMEGA328 processor. This board features a 14-pin “QuikEval” connector that can be plugged into nearly 100 daughter boards for various Linear Technology parts, including Analog to Digital converters, Digital to Analog Converters, high-voltage power monitors, temperature measurement devices, RF synthesizers, battery stack monitors, and more.

An LTM2884 USB Isolator breaks the ground connection to the PC, allowing projects to operate at a different ground potential than the computer that is controlling it.

Linduino is Linear Technology’s Arduino compatible development platform. Linduino is a package; it is a complete solution. Linduino has a board, the Linduino One. The Linduino One is a Arduino Uno compatible development board, with a twist, it comes with a LTM2884 uModule that provides full USB isolation. Even more importantly the board also comes with a 14 pin QuikEval connector that allows the Linduino One to directly connect to hundreds of LTC QuickEval compatible demo boards, already in existence.

However, the board is only part of Linduino. The real meat of Linduino is not the demo board but the library of example firmware that comes backing the One. The main goal of the Linduino program is to provide customers with example firmware to help them interact with Linear Tech’s parts. The Linduino One is merely there to provide a consistent development platform for the end customer. This library of code is intended to compile in any standard C compiler, we have taken steps to try to make the examples as portable as possible. As a matter of fact, the code is fully Arduino compatible, so if you have a spare Arduino Uno and the will to solder a couple of connections, you’re already ready to play. The goal of this entire package of goodies that we’ve built is to save time.

The idea is that a hardware engineer trying to interface a 24 bit ADC such as the LTC2449 into his circuit is a couple clicks away from loading the running, tested code into a microcontroller and talking to the part. Once the engineer is done with their testing, the example code snippets that were used can be ported over to the processor they are using for their end product. This should greatly shorten their development time.

Raspberry Pi

The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to learn programming.

Picture 1: Raspberry Pi

Basic Features:

1. SD card
• Minimum size 4Gb; class 4 (the class indicates how fast the card is);
• We recommend using branded SD cards as they are more reliable.

2. HDMI to HDMI / DVI lead
• HDMI to HDMI lead (for HD TVs and monitors with HDMI input) or HDMI to DVI lead (for monitors with DVI input);
• Leads and adapters are available for few pounds -- there is no need to buy expensive ones.

3. RCA video lead
• A standard RCA composite video lead to connect to your analogue display if you are not using the HDMI output.

4. Keyboard and mouse
• Any standard USB keyboard and mouse should work;
• Keyboards or mice that take a lot of power from the USB ports, however, may need a powered USB hub. This may include some wireless devices.

5. Ethernet (network) cable [optional]
• Networking is optional, although it makes updating and getting new software for your Raspberry Pi much easier.

6. Power adapter
• A good quality, micro USB power supply that can provide at least 700mA at 5V is essential;
• Many mobile phone chargers are suitable—check the label on the plug;
• If your supply provides less than 5V then your Raspberry Pi may not work at all, or it may behave erratically. Be wary of very cheap chargers: some are not what they claim to be;
• It does not matter if your supply is rated at more than 700mA.

7. Audio lead [optional]
• If you are using HDMI then you will get digital audio via this;
• If you are using the analogue RCA connection, stereo audio is available from the 3.5mm jack next to the RCA connector.

Siemens SIMEAS P Power Meter

SIMEAS P is a power meter for panel mounting with graphic display and background illumination. The major application area is power monitoring and recording at MV and LV level. The major information types are measured values, alarms and status information. Power monitoring systems with SIMEAS P, a permanently installed system, enables continuous logging of energy-related data and provides information on operational characteristics of electrical systems. SIMEAS P helps identify sources of energy consumption and time of peak consumption. This knowledge allows you to allocate and reduce energy costs.
Measured values include r.m.s values of voltages (phase-to-phase and/or phase-to-ground), currents, active, reactive and apparent power and energy, power factor, phase angle, harmonics of currents and voltages, total harmonic distortion per phase plus frequency and symmetry factor.

This digital power meter for panel mounting can be used in Measurement Circuit for 3-phase AC Power.

The SIMEAS P comes with two binary outputs, which can be configured for energy pulses, limit violations or status signals. The unit is also able to trigger on settable limits. This function can be programmed for sampled or r.m.s. values. SIMEAS P generates a list of minimum, average and maximum values for currents, voltages, power, energy, etc. lndependent settings for currents, voltages, active and reactive power, power factor, etc. are also possible. In case of a violation of these limits, the unit generates alarms. Up to 6 alarm groups can be defined using AND/OR for logical combinations. The alarms can be used to increase counter values, to trigger the oscilloscope function, to generate binary output pulses, etc. The inputs and outputs of the Simeas P Power Meter are shown on Picture 2.
