Starter kit for Qtouch library - QT600

The QT600 is a starter kit and development system for Atmel's AVR 8-Bit and 32-Bit RISC Flash microcontrollers.

ATMEL QTouch Library is a royalty free software library (available for GCC and IAR compiler tool chains) for developing touch applications on standard AVR and SAM microcontrollers.

The Library can be used to develop single chip solutions for control applications which have touch sensing capabilities, or to develop standalone touch sensing solutions which interface with other host or control devices.
  • USB Interface to PC
  • QT600 is powered by a USB interface
  • 3 MCU-boards (ATtiny88, ATmega324PA, ATxmega128A1)
  • 3 sensor boards for up to 64 channels
New Starter kit for Qtouch library

ATMEL QTouch provides a simple to use solution to realize touch sensing solutions on a range of supported ATMEL AVR Microcontrollers. The QTouch libraries provide support for both QTouch and QMatrix acquisition methods.

System-on-Chip - SoC - IP

When a product has to be made small, the board real estate is limited or it has to be manufactured in large numbers.... SoC is the Answer. A Microprocessor evolved into a Microcontroller by packing many external chips into one chip. Now uC Card along with the other blocks like A-D, Port Drivers, Networking elements, Display Driver and other peripherals can be packed into one chip.

System on a chip - Wiki

"A system on a chip or system on chip (SoC or SOC) is an integrated circuit (IC) that integrates all components of a computer or other electronic system into a single chip. It may contain digital, analog, mixed-signal, and often radio-frequency functions—all on a single chip substrate. A typical application is in the area of embedded systems."
System-on-Chip - SoC - IP

Some Power Supply and RF blocks cannot be easily added inside as they have a silicon processing more specific to their applications. Laser trimmed Instrumentation Op-Amps, high accuracy resistor arrays, high value capacitors, magnetics and supporting chips are placed outside on the PCB.

RS232 Serial Port and Terminal Emulation

You have to be familiar with serial interface and the traditional RS232 to understand basics of data communications. Have a desktop PC even an old one with serial and parallel ports for experimentation. Then work on USB, Ethernet and Wi-Fi Interfacing. Step by Step.
