The ATtiny series features a small package microcontroller with a limited peripheral set available. Main article: ATtiny microcontroller comparison chart Flash size The AVR is a modified Harvard architecture machine, where program and data are stored in separate physical memory systems that appear in different address spaces, but having the ability to read data items from program memory using special instructions.ДЄVRs are generally classified into following: The Arduino platform, developed for simple electronics projects, was released in 2005 and featured ATmega8 AVR microcontrollers. By 2003, Atmel had shipped 500 million AVR flash microcontrollers. The AVR 8-bit microcontroller architecture was introduced in 1997. The polarity of the RESET line was opposite (8051's having an active-high RESET, while the AVR has an active-low RESET), but other than that the pinout was identical. ДЄmong the first of the AVR line was the AT90S8515, which in a 40-pin DIP package has the same pinout as an 8051 microcontroller, including the external multiplexed address and data bus. The designers worked closely with compiler writers at IAR Systems to ensure that the AVR instruction set provided efficient compilation of high-level languages. When the technology was sold to Atmel from Nordic VLSI, the internal architecture was further developed by Bogen and Wollan at Atmel Norway, a subsidiary of Atmel. It was known as a ОјRISC (Micro RISC) and was available as silicon IP/building block from Nordic VLSI. The original AVR MCU was developed at a local ASIC house in Trondheim, Norway, called Nordic VLSI at the time, now Nordic Semiconductor, where Bogen and Wollan were working as students. Note that the use of 'AVR' in this article generally refers to the 8-bit RISC line of Atmel AVR microcontrollers. However, it is commonly accepted that AVR stands for Alf and Vegard's RISC processor. The creators of the AVR give no definitive answer as to what the term 'AVR' stands for. ДЄtmel says that the name AVR is not an acronym and does not stand for anything in particular.

The AVR architecture was conceived by two students at the Norwegian Institute of Technology (NTH), Alf-Egil Bogen and Vegard Wollan. 5 Development tools and evaluation kits.(Why Peter Fleury chose not to name the header file the same as the source file is a mystery for me, but that's another thing.

if you plan to use the twimaster/i2cmaster functionality in more than one project you might not want to have copies of the files in each project, so placing them (together) in a separate folder might be sensible. Exactly what folder that should be depends on things that are not known or spoken out in this thread. Still, understanding what goes on behind the scenes is worth a lot.) AVR Studio has a splace in the project settings/properties where you can specify include-file search paths (and Studio will use them to pass -IДЇor the question of placement of the include file: Since i2cmaster.h contains the prototypes etc for twimaster.c it makes sense that both files should reside in the same directory (or folder, in Windoze speak). (Yes, I realize that for someone going only with AVR Studio (v4 or v5) it might not be obvious that behind Studio the avr-gcc compiler is run and being passed options and arguments - hence the smilie. When everything else fails - read the documentation :wink:.
