HEX size Problem

[SSBISHT]

Hi Mikroelectronika Team,

I am using mikroC PRO for dsPIC30/33 and pic24 ver 5.8.1, my program is complied successfully and working fine.

But my problem is the generated hex file size is 387KB whereas I am using PIC24FJ256GA110 (PROGRAM MEMMORY SIZE 256K Bytes)
how this file has been fitted into this program memory. I am sure generated file is smaller than 256KB but why it is showing 387KB in project folder.

Another confusion after compilation massage says

Used ROM (bytes): 70106 (40%) Free ROM (bytes): 104990 (60%)

If we add 70106 + 104990 = 175096 but should be 262144 (256KB).

Best regards

Sunny

The size of the hex file is at least the double of the size of the actual code. The hex file is a textfile: every byte is shown a 2 characters in addition to the addresses, checksums etc. that are also present in the hexfile.

Hi Dany,

Thanks for prompt response, could you please explain me about
this massage generated by compiler.

Yes.
The reason for this is that the unit used is not "bytes" but something else (approx 1.5 bytes), so if you multiply the figures with 1.5 you will get the right numbers in bytes.
