With appreciable program memory it can satisfy most EMBEDDED SYSTEMS. With various sleep modes it can work on MOBILE EMBEDDED SYSTEMS. Along with 32 programmable Input/Output pins, it can interface many peripherals easily. With Watchdog timer to reset under error it can be used on systems with no human interference. With so many features with each appreciating other we can implement ATMEGA32 in many control systems. How to Use ATMEGA32 Using ATMEGA32 is similar to any other microcontroller. Similar to them it is not Plug and Play digital ICs. For working of ATMEGA32, first we need to save the appropriate program file in the ATMEGA32 FLASH memory. After dumping this program code, the controller executes this code to create the response. Entire process of using an ATMEGA32 goes like this: • List the functions to be executed by ATMEGA32 • write the functions in IDE programs using relative language (Usually Atmel Studio 6.2 for Windows7, Atmel Studio 7 for Windows10 (For these IDE the functions should be written in ‘C’ language) • After writing the desired program compile for error elimination using IDE. • Opt the IDE application to generate HEX file for the written program. • Choose the programming device (usually SPI programmer made for AVR controllers) which establishes communication between PC and ATMEGA32 • Run the HEX file dumping software which is related to the chosen programming device. • Choose the appropriate program HEX file in the SPI or other programmer software. • Burn the HEX file of program in ATMEGA32 flash memory using this program. • Disconnect the programmer, connect the appropriate peripherals for the controller and power the sytem. Applications There are thousands of applications for ATMEGA32. • Temperature control systems • Analog signal measuring and manipulations. • Embedded systems like coffee machine, vending machine. • Motor control systems. • Digital signal processing. • Peripheral Interface system.
