Hi Team,

I have saw thread

This thread provide a method to transmit more than 64 bytes.

But I have 2 more questions:

Does Task_sleep(1) means 1us or 1ms delay in SDK OOB demo? What's the default value in OOB demo.
If I want to transmit data continuous without any sleep, does it has a sign can point out the data has already transmitted by CANFD? So we can start transmit next data package.

Thanks for your help.

Regards,

Wesley

Hi,

Please check the RTOS documentation for units of Task_sleep(1).

So, you would like to send CAN FD data based on an interrupt?

Thank you
Cesar

Wesley, the BIOS function Task_sleep() is in units of clock ticks. The real delay will be bigger of course, due to overhead reasons. Have you tried it without a task sleep? Or possibly inserting a NOP?

Hi:

I tried to use transmit interrupt to contious CAN data, but I want to turn off global interrupt when I push a can data in my own FIFO, where can I find the global interrupt control API? Thank you!

Please see chapter 20 of www.ti.com/.../swru522a.pdf.

There are registers that all you to CAN disable interrupts.
