hi,

there is an issue came up during my project. please help me.
we have decided to use the microcontroller PIC24HJ256GP610 for our project. for this micro do we really need MICROCHIP REAL ICE for debugging?? will ICD2 alone will do? what is the diofference between the working of REAL ICE and ICD2?
can we set hardware breakpoints using ICD2?
regards,
deepa
 

ice vs icd

Most of the PIC projects could be done with simple serial or parallel port programmers. If you have complex program with interupt driven tasks it can get complicated and ICD is limited compared to full blown ICE, as ICD uses some of hardware resources of PIC to perform it's function. You can find more detail on Microchips site. Going through your code and isolating parts of it usually solves misteries of goblins and ghosts that appear in otherwise perfect coding :)
 
real ice icd2

Hi!

ICD and REAL-ICE uses are debuggers for pics, both of them uses the internal hardware of pic for debug, but real-ice can go faster than icd2 (ICD2 is full speed usb, 12Mb/s, REAL-ICE is high speed usb, 480Mb/s).

With REAL-ICE you can see variable values in real time, you can implement more complex breakpoints (as breakpoint when a variable has certain value, etc), etc...

But is not a real emulator, if the pic only has 1 icd-breakpoint, you only can implement 1 breakpoint...

Regards,
