Debugging C function with external key press?

[abid_ms]

Hi,

Can anybody tell me the solution....?

I have a C function running in Keil IDE. This will be invoked with any key press of the external keypad. Now, how can I debug the code in my function with key press?

I mean, how can any debug a C prog with external interrupts in keil; because we will be downloading the created .hex file through serial communication which is no way conneteced to my keil IDE.

Suggesstions and solutions are welcome in this regard.

Thanks in advance,
abid.

It's possible with a JTAG emulator.

In my opinion, I think simulation on PROTEUS (http://www.labcenter.co.uk)
can help you.
