AWR1843BOOST: To increase the time between each CAN Frames

Rehman
Intellectual 255 points
Part Number: AWR1843BOOST
Other Parts Discussed in Thread: AWR1642

Tool/software:

Hai,

In MRR demo currently the CAN is sending frames at a very high speed. In PCAN View the cycle time is showing 0.2.

Is there any way to increase the time interval between CAN output frames.

We tried to add Task_Sleep inside the Can_Transmit_Schedule() function, but the radar is getting stuck.

Regards,

Rehman

    Hi,

    The demo must send the processed data every frame. If I remember correctly, for MRR mode, the frame duration is 30ms.

    The function Can_Transmit_Schedule() is called for every results buffer we want to send.

    Thank you

    Hai ,

    Actually what i meant is , i wanted delay after each CAN message. Each TLV may contain some given number of CAN(8 bytes data) messages on the basis of the number of objects detected.

    But what we want is a to get a controlled delay between each CAN output message.

    Regards,

    Hi,

    If you are trying to delay internally the CAN transmission, than I recommend searching for more resources on the internet. The CAN TX used in our device is standard and similar to other embedded devices. So information will apply to our device. 

    Unfortunately our team does not have much experience with CAN because most of our customers are experts with this peripheral

    thank you

    Hai,

    But for Chinese Radars the cycle time in PCAN view is showing 50 and ours it's showing 0.2.

    The  Chinese Radars are using AWR1642.

    Yes, probably the software is not identical to MRR available on  Radar Toolbox.

    Unfortunately our team is not expert on the CAN peripheral.

    I recommend searching the e2e forum using google site search for similar questions

    For example

    site e2e.ti.com AWR CAN cycle time

    Thank you
