Atmel AVR STK500 Communicating with a User Manual Host PC and Temperature Sensor 4 Application Programming 4 2 Uploading an Application Programming the Board It is important to remember that the target microcontroller installed on the STK500 is what is actually being programmed Only HEX file programs can be uploaded to the flash memory of the target MCU and only HEX or ROM file programs can be uploaded to the EEPROM memory of the target MCU The flash memory of AVR microcontrollers is typically what is programmed because of its available space and relatively unlimited read and write life cycles EEPROM memory has a limited write life cycle so only programs that will be used frequently and remain relatively unchanged are reserved for EEPROM 10 This project focuses on the use of the flash memory only The STK500 PCB has a specific RS 232 communication protocol that requires data to be received for in system programming using eight data bits one stop bit and no parity at 115 2 kbps i e at a rate of 115200 baud 14 The following subsections describe two ways of using this protocol to upload an application to an STK500 board 4 2 1 Using a Command Line Utility to Program the STK500 The microcontroller installed on an STK500 can be programmed using the Windows command line utility CMD The CMD session must be in the same directory as the Stk500 exe program which is located in C Program Files Atmel AVR Tools STK500 when AV

R Studio is installed in its default directory The Stk500 exe program is an STK500 DOS programmer provided by Atmel It can be copied and pasted to any desired location after AVR Studio is installed The HEX file that will be programmed to the board must either be in the same location as the Stk500 exe program or its directory must be provided in the command line used to program the board the preceding option is recommended and is used for the sample DAQ project provided in this document Any pre existing HEX file can have its name changed without it losing its functionality A list of all applicable commands is given in the STK500 User Guide 1 Being able to use CMD allows for a batch file bat to be created that automatically programs the board when the file is opened A batch file is simply a text file that contains CMD commands that will be executed line by line within a CMD session as soon as the file is opened The batch file given in Vincent A Rosa Florida Gulf Coast University Page 1 of 11 Spring 2009 Atmel AVR STK500 Communicating with a User Manual Host PC and Temperature Sensor Appendix section A 2 2 3 provides an example of how the command utility can be used to program the STK500 The following list of commands and how they are used accompany the instructions that provided an example of how to use the CMD to program an ATmega8515L MCU when it is installed in a target socket on an STK500 Before performing the following instructi
