Atmel SMART | SAM V7: Cortex-M7 Tutorial Using the SAMV7 Xplained ULTRA evaluation board ARM Keil MDK 5 Toolkit Summer 2017 V 1.83 [email protected] Introduction: The latest version of this document is here: www.keil.com/appnotes/docs/apnt_274.asp The purpose of this lab is to introduce you to the Atmel Cortex®-M7 processor using the ARM® Keil® MDK toolkit featuring the IDE μVision®. We will demonstrate all debugging features available on this processer including Serial Wire Viewer and ETM instruction trace. At the end of this tutorial, you will be able to confidently work with these processors and Keil MDK. We recommend you obtain the new Getting Started MDK 5: from here: www.keil.com/gsg/. Keil Atmel Information Page: See www.keil.com/atmel. Keil MDK supports and has examples for most Atmel ARM processors and boards. Check the Keil Device Database® on www.keil.com/dd2 for the complete list. Additional information is listed in www.keil.com/Atmel/. Linux: Atmel ARM processors running Linux and Android are supported by ARM DS-5™. http://www.arm.com/ds5. Keil MDK-Lite™ is a free evaluation version that limits code size to 32 Kbytes. Nearly all Keil examples will compile within this 32K limit. The addition of a valid license number will turn it into a commercial version. Contact Keil Sales for details. Atmel 8051 Processors: Keil has development tools for many Atmel 8051 processors. See www.keil.com/Atmel/ for details. Atmel | Start: µVision is compatible with the Atmel | START configuration program. -

Introduction to AVR®
Introduction to AVR® By BiPOM Electronics, Inc. Revision 1.02 © 2011 BiPOM Electronics, Inc. All rights reserved. All trademark names in this document are the property of their respective owners. AVR® History · The AVR® architecture was conceived by two students at the Norwegian Institute of Technology. · The original AVR® was known as μRISC (Micro RISC). · Among the first of the AVR® line was the AT90S8515, which in a 40-pin DIP package has the same pinout as an 8051 microcontroller. · The creators of the AVR® give no definitive answer as to what the term "AVR" stands for. AVR® Features · Some 8-bit, some 32-bit · TinyAVR, megaAVR, XMEGA, FPSLIC · Harvard Architecture for 8-bit devices: Separate code and data space · Flash, EEPROM and SRAM are all on a single chip, eliminating the need for external memory. · All code executed by the AVR® core must reside in the on-chip flash. · Most instructions take just one or two clock cycles. · The AVR family of processors were designed with the efficient execution of compiled C code in mind. Why AVR® ? · The AVR® instruction set is more powerful than PIC or 8051. · The AVR® runs instructions very fast (can execute 1 instruction in 1 machine clock cycle) · AVR® is a good choice for industrial projects. Frequently Asked Questions Can AVR® run an OS? - Yes, AVR32 can run Linux core 2.6.XX with BusyBox What programming languages are for programming AVR® microcontroller? - There are many different languages but most commonly used are C and BASCOM BASIC. Does BiPOM offer AVR® design services ? – Yes,
