Microchip announced a new family of PIC32MX1/2 microcontrollers (MCUs) in 256/64 KB Flash/Ram configurations. These new MCUs are coupled with comprehensive software and tools from Microchip for designs in digital audio with Bluetooth®, USB audio, graphics, touch sensing and general-purpose embedded control.

This is the CPU board with a 8-bit microcontroller PIC12F629, a 20MHz crystal and a bypass capacitor to reduce the noise. This little board goes into a 70-210mm f/2.8 lens and an identical one is made for a 28mm f/1.8 lens. There is an internal oscillator but can only run at 4 MHz which is too slow for this application.
With only 35 instructions to learn the Microchip PIC microcontroller assembler language is considered very efficient and easy to learn; you will not find such as Atmel AVR microcontroller CP (compare) and BRNE (branch if not equal) or BRGE (branch if greater or equal) on the PIC microcontroller assembler language dialect, instead it’s just provide us with a very simple bit test and skip one line instruction.

Microchip announced an expansion of its 8-bit PIC® microcontroller (MCU) portfolio, with the peripheral-rich, low pin count PIC16(L)F161X family. These new MCUs expand the offering of Microchip’s Core Independent Peripherals (CIP), which offload timing-critical and core-intensive tasks from the CPU, allowing it to focus on other application tasks. Additionally, this family integrates fault-detecting hardware features to assist engineers in developing safety-critical applications. For more info, visit: www.microchip.com/get/VLDM

Microchip Technology's PIC18F87J72 Single-Phase Energy-Meter Reference Design (Part # ARD00280) features a shunt-based single-phase meter with energy-calculation firmware and GUI-assisted software calibration, the reference design enables calculation of active/reactive energy, forward/reverse energy, active/reactive/apparent power and RMS current/Voltage. Customers can reuse or customize the free firmware for their needs, which further shortens time to market and enables them to differentiate their products in the marketplace.
Microchip Technology Inc., a leading provider of microcontroller, analog and Flash-IP solutions, today announced its first instrumentation amplifier, the MCP6N11. The new instrumentation amp features Microchip’s unique mCal technology, which is an on-chip calibration circuit that enables low initial offset voltage and a means to control offset drift, which results in higher accuracy across time and temperature. The MCP6N11’s low-power CMOS process technology enables low power, while providing a gain bandwidth product of 500 kHz, and it features a hardware shutdown pin for even more power savings. The device’s low, 1.8V operation allows two 1.5V batteries to be drained beyond typical use, and its rail-to-rail input and output operation enables full-range use, even in low-supply conditions.
Each wheel has three optical sensors, an Arduino microcontroller board, an audio amplifier and a battery pack. They play generative music as the wheel turns.

One of the advantages using the Microchip PIC microcontroller Pulse Width Modulation or PWM for short is; this PWM peripheral circuit is designed to control the DC motor using the full bridge mode PWM feature. The PWM peripheral works by supplying the correct signal to the H-Bridge DC motor circuit such as speed controlling and changing the DC motor direction.

The PIC16F75X family of 8-bit microcontrollers (MCUs) featuring intelligent analog and core-independent peripherals, making them ideal for general-purpose applications, as well as power supplies, battery charging, LED lighting, power management and power control/smart energy applications. The new PIC16F753 MCU builds on the success of the popular PIC12F752. The PIC16F753 offers all the key features of the PIC12F752, such as the integrated Complementary Output Generator (COG) peripheral that provides non-overlapping, complementary waveforms for inputs such as comparators and Pulse Width Modulation (PWM) peripherals, while enabling dead-band control, auto shutdown, auto reset, phase control and blanking control. Additionally, the PIC16F753 offers an Op Amp with 3 MHz of Gain Bandwidth Product (GBWP), and a slope compensation circuit to help in Switch Mode Power Supply applications.

The Arduino Uno is a microcontroller board based on the ATmega328
It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz crystal oscillator, 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.

Talks and performances by people doing strange things with electricity
Fri 23 March 2012, 6.30-10pm with interval at the Showroom Cinema, Sheffield.
Dorkbot is a meeting of people interested in electric/electronic art in the broadest sense; robotics, kinetic art, microcontrollers, interactive art, algorithmic music, net.art... The only real conditions are that it is a bit strange and involves electricity in some way. It is really defined by whoever turns up, be it engineers who want to be artists, artists who want to be engineers, or the otherwise confused.
This MEGADORK event features a cabaret of talks and performances from among the UK's dorkiest, to entertain and amaze:
Paul Granjon - A strange performance from the world renowned self-styled robot artist.
Patrick Tresset - Talks about his drawing robot Paul (on show as part of the Alan Turing: Intuition and Ingenuity exhibition).
Daniel Jones and James Bulley - talking about generating live music from patterns of weather.

Sarah and Jenny Angliss - playing robot music from past futures.

Sergi Jorda - talks about the Reactable tangible tabletop music playground (which you'll be able to try out at the Central Library Saturday 24 March)
Dan Stowell - Demonstrates his use of the Risset illusion in techno music.
Silicone Bake - Live coded pop songs about love, death and counterfeit watches, where all lyrics are taken from spam emails.
Megadork is curated by Alex McLean.
Dorkbot started in New York, spread to London, and now dozens of cities around the world, including several active UK chapters; Sheffield, Bristol, Anglia, Newcastle, Cardiff and Alba (Scotland). Find out more at: www.dorkbot.org

I2C (read as I Square C) bus first introduced by Philips in 1980, because of its simplicity and flexibility the I2C bus has become one of the most important microcontroller bus system used for interfacing various IC-devices with the microcontroller. The I2C bus use only 2 bidirectional data lines for communicating with the microcontroller and the I2C protocol specification can support up to 128 devices attached to the same bus.
