Part Number: TMS320F28P659DK-Q1

Dear experts,

May I know the maximum speed from the ESC's mailbox to the memory? How much resources (MIPS, memory....) will cost when ESC run in C28 core? Thank you.

Hi Sahil,

Any update? The other question is have you evaluate the performance if customer use one C28 core to complete etherCAT communication and motor control? Any risk? Thank you.

Hi Angela,

I have not been able to dedicate bandwidth to this as I would have liked. I will get back to you on this by Wednesday, 24th April at the latest.

Thanks.

Angela,

Apologies for the late response but I really hoped to do some benchmarking now which I wasn't able to do.

Here are the results of some tests that were done previously that are available in the Example User Guide.

Hope this helps.

Thanks.
