TMS320F28075: deprecated file

Howard Zou

Part Number: TMS320F28075
Other Parts Discussed in Thread: C2000WARE

Hello, in our CAN example project.

It's using can.c,  and it's located in deprecated file.

C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2807x\common\deprecated\driverlib

We also have F2807x_can.c which is in 

C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2807x\common\source

1. Why we are using deprecated file?

And we have Deprecated_F2807x_DRL_UG in 

C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2807x\common\deprecated

we also have F2807x_DriverLib_Users_Guide in

C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2807x\docs

2. which should I refer to ?

    There are currently 3 different ways to interact with CAN:
    - The deprecated drivers (these were a small set of developed drivers and are no longer getting updated)
    - The bit field struct headers
    - The new driver library

    Unless you want to use bit fields, I highly recommend using the new driver library. You can find this in the /driverlib root directory of C2000Ware. The documentation for this is what you referred to in device_support\f2807x\docs

    Best regards

    So the deprecated drivers should not be used.
    But in our example project.
    C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2807x\examples\cpu1\can_loopback
    there will be a can.c file from
    C:\ti\c2000\C2000Ware_1_00_06_00\device_support\f2807x\common\deprecated\driverlib

    Not from
    C:\ti\c2000\C2000Ware_1_00_06_00\driverlib\f2807x\driverlib

    And the two can.c files are not the same.

    Yes, we've continued to include those examples for anyone still previously using those deprecated functions.
    For CAN examples using the new driverlib, they are next to the new driverlib directory at C:\ti\c2000\C2000Ware_1_00_06_00\driverlib\f2807x\examples

    Best regards
