AVRdude is bundled with WinAVR compiler and is a command line program for burning hex code into AVR ICs.
Before starting the Avrdude , connect the Usbasp programmer to your PC.
Press WIN+R to open up the Run dialog box.Type cmd.exe to open the Terminal window.Navigate to the folder where we created our .Hex & other files.In our case it is C:\LED_TEST.
to view the list of options used with avrdude.
-c : Indicates the programmer type (use usbasp as argument)
-p : Processor. (We are using ATmega16, hence type m16 as argument ).
-U : memtype:op:filename[:format]
-U is the command to fuse .hex file on to AVR’s memory. Multiple ‘-U’ options can be speciﬁed in order to operate on multiple memories on the same command-line .
Here is the command we use to program our blinkled.hex file.
Take care of casing of letters (small or capital letter), as the command is case sensitive.
C:\LED_TEST> avrdude –c usbasp –p m16 –u –U flash:w:blinkled.hex
