when KEA EEPROM Emulation , the frame period of message CAN is affected.

[ericka]

when I use KEA128 ,if I WriteEeprom  ,MCU will Close the interrupt  and then affects timer timing.

So the frame period of message CAN is affected.

How can I do about this,thanks!

Hi Yang liu,

    As I know, the KEA128 don't have the eeprom, I think you mentioned the flash writing, yes, when do the flash operation, it's better to close the interrupt, otherwise, the flash operation may be failed.

   So, I think, in the application side, you need to consider the relationship between the CAN and the flash operation.

   Maybe you don't need to write flash very quickly, after collect enough data, then write to the flash together, in the CAN communication side, you also need to consider the flash write time, just design the app logic, minimize the flash operation influence to the CAN.

Have a great day,
Kerry
