Other Parts Discussed in Thread: TMS320F2812, CONTROLSUITE

Good Day,

I used TMS320F2812 eZdsp to perform ADC. The results from the ADC is used to perform a mathematical computation.

I would like to know how to get the processing time from the start of the program up to i finish execute my program.

Thank you. Appreciate any help.

Regards,

Hi LinE,

the simplest way to measure execution time is to set a GPIO pin @ programstart and clear it when your program finishes. Observe this pin with a scope.
If you work with DSP/BIOS there are other possibilities.... but don't ask me how to do it as I am not using BIOS!

Best regards

Andreas

I'm using non-bios. I'm quite new for GPIO. How do i set a GPIO pin @programstart? Could you explain briefly how to perform this?

Thank you

download the controlsuite software from ti - there are a lot of examples available how to work with the peripherals...
