The Atmel AVR instruction set is the machine language for the Atmel AVR, a modified Harvard architecture 8-bit RISC single chip microcontroller which was developed by Atmel in 1996. The AVR was one of the first microcontroller families to use on-chip flash memory for program storage.
debugWIRE is supported by all modern hardware debuggers from Microchip.This includes Atmel-ICE, [3] JTAGICE3, AVR Dragon, JTAGICE mkII, and SNAP. [4] It is also possible to build a cheap debugWIRE hardware debugger [5] based on an open-source Arduino sketch, [6] using a general USB-Serial adaptor or ATtiny85 board, [7] or a CH552 microcontroller.
The AVR Dragon provides in-system serial programming, high-voltage serial programming and parallel programming, as well as JTAG or debugWIRE emulation for parts with 32 KB of program memory or less. ATMEL changed the debugging feature of AVR Dragon with the latest firmware of AVR Studio 4 - AVR Studio 5 and now it supports devices over 32 KB of ...
C Programming for Microcontrollers, a book for learning to program AVRs using C, was written for the Butterfly as development platform. [6] [7] The Butterfly Logger is an open source data logger based on the AVR Butterfly. [8] The Butteruino project is a set of libraries to integrate the AVR Butterfly with the Arduino development environment. [9]
MicroPython is a software implementation of a programming language largely compatible with Python 3, written in C, that is optimized to run on a microcontroller. [2] [3] MicroPython consists of a Python compiler to bytecode and a runtime interpreter of that bytecode.

ATmega328 is commonly used in many projects and autonomous systems where a simple, low-powered, low-cost micro-controller is needed. Perhaps the most common implementation of this chip is on the popular Arduino development platform, namely the Arduino Uno, Arduino Pro Mini [4] and Arduino Nano models.
Note that for (A0)+ and −(A0), the actual increment or decrement value is dependent on the operand size: a byte access adjusts the address register by 1, a word by 2, and a long by 4. PC (program counter) relative with displacement Relative 16-bit signed offset, e.g. 16(PC). This mode was very useful for position-independent code.
