FlexCAN module with FIFO in MK60F12

tiborsomogyi — Fri, 30 Mar 2018 09:07:53 GMT

Hello,

I try to use the the CAN module of the MK60FN1M0VLQ12 ( on the TWR-K60F120M board ). The manual - K60F_K60P144M150SF3RM.pdf - says that FlexCAN supports the reception via FIFO, but when I select the FIFO option with Processor Expert, it displays an error saying "the component does not support this setting".

So, to be or not to be... :-) ... Could someone clarify this issue, please ?

Thanks and regards

Tibor

Hi,

Yes, the Processor Expert IDE or the Processor Expert on CW IDE only support the feature for MSCAN device.

As workaround you could use "Message buffers" or freeze the code of this component and implement it manually. Please make this post as a reference: https://community.nxp.com/message/351971

Hi,

Thank you for your response and for the reference - and really sorry, but the issue is still not clear for me. I understand now that the Processor Expert CAN component does not support the FIFO operation, however I still uncertain about whether the FlexCAN module of the MK60FN1M0VLQ12 MCU itself can work in FIFO configuration or not. Could you clarify this, please ?

Thanks and regards

Hello, Tibor

Yes, the K61 FLEXCAN support FIFO from hardware itself.

Hello,

Thanks for your post… and sorry, but still not completely clear about the issue: you wrote that the K61 FLEXCAN supports the FIFO from hardware… but I am using the K60 MCU… does the K60 FLEXCAN support the FIFO, as well ?

Thanks and regards

Hi, Tibor

Sorry, my fault. Same case for K60.

Hi Fang,

Thanks for the clarification… now it is crystal clear … and so I start to implement the CAN reception via the FIFO….

Cheers
