Hi everyone,

Is it possible to display the execution time of sections of code within DAVE 4 ?

For example the time to execute a function.

Thank you very much

You can toggle an output at start and end of your code. This way you can measure with a scope how long it takes.

good luck.

Jesus, thanks for the blog link. Have you tried this method on the Infineon XMC parts ?

NIcky, thanks for the suggestion, it's exactly what I do normally. It's very reliable but means modifying code with the risk of forgetting to delete it prior to code release and it finding it's way into production.

Best regards

The cycle counter is an standard feature of all ARM Cortex-M4, therefore all XMC4 support it.
For XMC1 you can go with the system timer which runs at the same frequency as the CPU, although it is "only" 24bit timer.
