What is the Atmel AVR assembler?

4.1 Introduction Welcome to the Atmel AVR Assembler. This manual describes the usage of the Assem- bler. The Assembler covers the whole range of microcontrollers in the AT90S family. The Assembler translates assembly source code into object code.

Do I need to learn assembly language to program AVRS?

Many people that are deeper into programming AVRs and use higher-level languages in their daily work recommend that beginners start with learning assembly language. The reason is that sometimes, namely in the following cases:

How does an assembler work?

Most important for understanding assembler is to understand how the CPU works. The CPU reads instructions (instruction fetch) from the program storage (the flash), translates those into executable steps and executes those. In AVRs, those instructions are written as 16 bit numbers to the flash storage, and are read from there (first step).

Is assembler easy to learn?

Assembler is easy to learn. It is not true that assmbly language is more complicated or not as easy to understand than other languages. Learning assembly language for whatever hardware type brings you to understand the basic concepts of any other assembly language dialect. Adding other dialects later is easy.

How difficult is it to correct typing errors on Atmel chips?

To correct typing errors is as easy or complicated as in any other language. Basic design errors, the more tricky type of errors, are also as complicated to debug like in any other computer language. But: testing programs on ATMEL chips is very easy.
