Hi all,

I recently received the LPCXpresso 1343 board. Before that I downloaded the LPCXpresso IDE.
I wonder if it possible to show the elapsed execution time in the Xpresso IDE during debugging?

Can anyone help me with this issue please,

Thanks!

Hi,

In the Core Registers window, you will see 2 registers:
Cycle
- this is the total number of cycles executed by the processor (since Reset). If you know the clock speed, you can simply calculate the execution time.
Cycle Delta
- this is similar to Cycle, but is the number of cycles executed since the last debug event (e.g. breakpoint). Again, it is simple to calculate the executaion time from that.

Note that these registers are only available in Cortex-M3 processors (LPC17, LPC13)
