DSPIC HEX FILE
PostPosted: Tue Nov 18, 2014 7:34 am     Reply with quote
Hello,

I am using a DSPIC33FJ64GP802.

I would like to know if I place this in the code:

Code:
const int Test[]={125,126,127,128};


Can I find these values in the hex file so that I can modify them without having to re compile?

Thanks!

You can #org it at a specified address. See this thread:
http://www.ccsinfo.com/forum/viewtopic.php?t=51976
Then you can look in the hex file at that address.

Hello and thanks for the reply.

I used
Code:
#ROM 0XA000 = {0X0A,0X0B,0X0C}


and I can see the values in the hex file.

Now, how can I read these values during runtime?

Not as easily as a variable. You have to use the read_program_memory command.
Look at the #ORG solution, PCM_Programmer has already given. Makes the code a lot simpler.
You can also find 'where' a const is without ORG, by using 'label_address', which will tell you where it is, but this is only useable in the code.
