Hello, I am using the Simulink Support Package for Arduino Hardware (Matlab R2013b). It is programming the code to the target successfully. How can I find the size of the program written for the UNO?

Comparably, when I use the Arduino IDE, after programming the hardware, the log window will state something like: "Binary sketch size: 1,082 bytes (of a 32,256 byte maximum)" . I would like to know the size of what Simulink is programming so that I have an understanding of how much space is still available.

Hi Scott Garabedian,

The size of the of program, deployed onto the board, is displayed on the MATLAB Command prompt from MATLAB 8.3 (R2014a) onwards.

For previous releases, you may have to use the 'avr-size' utility present in arduino-x.x/hardware/tools/avr/bin. The format to use it in system command prompt is :

avr-size filename.elf

Hope it helps, Abhishek

Thank you for the help. Here is the response it gave me:

   text    data     bss     dec     hex filename
  25632     352     276   26260    6694 Arduino_Blink.elf

So the program size is text + data + bss = 26260 bytes? 26260/32256 = 81.4% full? Am I understanding this correctly?

Hi Abhishek, can you confirm my calculation in the previous comment? Is the program 81.4% full?
