imxrt1050 Flexcan Polling, FIFO and Masking

[michaelsmorto]

I have been working with Flexcan on the imxrt1050 and the interrupt examples works with no problem.  Also modified it to work so it receives and transmits with out interrupts but still uses the same basic masking and setup for tx and rx.

Now I have a three part question:

1.  Do you have any examples for setting up flexcan for polling mode?

2.  Do you have any examples for setting up flexcan in fifo mode?

3.  Masking set up is confusing the heck out of me.  For instance how to do you set the mask up in any of the modes to accept any msg.id?  Especially since it is also driven by "    FLEXCAN_SetRxMbConfig(EXAMPLE_CAN, RX_MESSAGE_BUFFER_NUM, &mbConfig, true);"  So what would this be to receive any msg.

Thanks in advance.

Hi Michael Smorto,

Thank you for your interest in NXP Semiconductor products and for the opportunity to serve you.
Q1) Do you have any examples for setting up flexcan for polling mode?
-- Until now, there's the similar demo in the SDK library now, it needs the developer to modify the current the FlexCan demo.
Q2)  Do you have any examples for setting up flexcan in fifo mode?
-- Until now, there's the similar demo in the SDK library now, it needs the developer to modify the current the FlexCan demo.
If you have any further questions about the modification, please feel free to contact me.
Q3)  Masking set up is confusing the heck out of me.  For instance how to do you set the mask up in any of the modes to accept any msg.id?  Especially since it is also driven by "    FLEXCAN_SetRxMbConfig(EXAMPLE_CAN, RX_MESSAGE_BUFFER_NUM, &mbConfig, true);"  So what would this be to receive any msg.
-- Actually, I'm not very clear with this question, whether you can clarify it.
Have a great day,
TIC
