AWR1642BOOST: How to transmit data through CAN bus

Katherine Wang

Part Number: AWR1642BOOST

Hi Team,

I am currently using the lab0002_short_range_radar in mmwave_automotive_toolbox_3_6_0 for development and add CAN code in accordance with the following example.

https://www.ti.com/lit/an/spracg9/spracg9.pdf?ts=1676271953707&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FAWR1642%253Futm_source%253Dgoogle%2526utm_medium%253Dcpc%2526utm_campaign%253Depd-null-null-gpn_en-cpc-pf-google-tw%2526utm_content%253Dawr1642%2526ds_k%253D%25257b_dssearchterm%25257d%2526DCM%253Dyes%2526gclid%253DEAIaIQobChMI3KmVw_eR_QIVzlBgCh2zbQ90EAAYASAAEgKiFvD_BwE%2526gclsrc%253Daw.ds

https://www.ti.com/lit/an/spracf7/spracf7.pdf?ts=1676274810242&ref_url=https%253A%252F%252Fwww.ti.com%252Fproduct%252FAWR1642%253Futm_source%253Dgoogle%2526utm_medium%253Dcpc%2526utm_campaign%253Depd-null-null-gpn_en-cpc-pf-google-tw%2526utm_content%253Dawr1642%2526ds_k%253D%25257b_dssearchterm%25257d%2526DCM%253Dyes%2526gclid%253DEAIaIQobChMI3KmVw_eR_QIVzlBgCh2zbQ90EAAYASAAEgKiFvD_BwE%2526gclsrc%253Daw.ds

But I encountered many problems meanwhile, such as the parameter 'undefined' in the function.

I would like to know

1. How to define these parameters (socHandle, DCAN_APP_INPUT_CLK, DCAN_APP_BIT_RATE...)? Is there any documentation available for reference?

2. Is it feasible to observe whether AWR1642BOOST has transmitted correct data through CAN analyzer?

ex.

If it is possible, is there a sample project or sample code that can transmit data through CAN? (I have tried lab0005_object_data_over_can, but it cannot work normally.)

Thanks and regards,

Katherine

    Hi,

    The examples provided in the documents mentioned use probably older versions of the SDK.

    You would need to make the updates for the SDK being used.

    The

    mmwave_automotive_toolbox_3_6_0\labs\lab0002_short_range_radar uses the SDK 3.5 as mentioned in the release notes.

    The canfd unit test provides an example how to initialize the can driver

    C:\ti\mmwave_sdk_03_05_00_04\packages\ti\drivers\canfd\test\xwr18xx\main.c

    This example shows how to initialize the CAN FD driver for SDK 3.5

    Regarding the "lab0005_object_data_over_can" this lab has been tested and it is working.

    It supports SDK 2.1.0.4

    mmwave_automotive_toolbox_3_6_0\labs\lab0005_object_data_over_can

    The canfd unit test included in SDK 2.1.0.4 also shows how to init the canfd driver with this SDK

    C:\ti\mmwave_sdk_02_01_00_04\packages\ti\drivers\canfd\test\xwr16xx\main.c

    Thank you

    Hi Cesar,

    Currently, the SDK I'm using is mmwave_sdk_03_06_00_00-LTS.

    If I want to use C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\drivers\canfd\test\xwr16xx\main.c for CAN data transmission test, could you tell me how to generate bin file to program to AWR1642BOOST?

    Because the sample program in C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\drivers\canfd\test\xwr16xx\main.c is not a CCS project, the bin file cannot be generated through the Build Project.

    In addition, I would like to whether the role of the sample code 'C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\drivers\canfd\test\xwr16xx\main.c' is to transmit the following data through CAN bus?

    Regards,

    Katherine

    Please follow the instructions in the mmwave user guide, section "Building drivers/control/alg components"

    C:\ti\mmwave_sdk_03_06_00_00-LTS\docs\mmwave_sdk_user_guide.pdf

    In order to build the canfd example you will need to use the makefile provided in

    C:\ti\mmwave_sdk_03_06_00_00-LTS\packages\ti\drivers\canfd

    Unfortunately there is no ccs project available

    Yes, this data is transmitted through CAN. However these are loopback examples

    thank you
