BOOSTXL-DRV8320RS: Need guidance on labs for DRV8320RS MotorControl SDK with TMS320F280049C

Part Number: BOOSTXL-DRV8320RS
Other Parts Discussed in Thread: DRV8320

I am using the Instaspin projects and Lab User's guide .

In lab3 section, it says below.
Step 1: Declare a PWMDAC object in “is03_hardware_test.c”.
Step 2a: Set the correct offset and gain for each PWMDAC channel.
Note: Follow step 2a to monitor the ANGLE_GEN for rotor angle and SVGEN for PWM output.

What should I do for step1?
What should I do for step2? Should I modify the values of offsets and gains if needed? Do you have any guidance on how to go about doing that?

It is very unclear to me, how to perform the PWMDAC steps. What should I do for step1, step2a etc… I need more details on how to see the output waveforms of the PWMDACs are as shown in Figure 28.

    The PWMDAC function can't be used on the LuanchPad-F28049 with BOOSTXL-DRV8320RS since there is no circuit for PWMDAC on the LuanchPad-F28049.  It's just for the high voltage kit with F280049C control card. Please ignore this PWMDAC function.

    What about DATALOG_DMA?

    In InstaSPIN Projects and Labs User’s Guide, the table that summarizes all the projects are available and apply for Boost8320. Is this partially not true?

    Can you please let me know what else will not apply so that I don't waste my time.

    The PWMDAC is disabled and Datalog is enabled in all the example labs of the DRV8320 if you have tried to run some labs with CCS. Sorry for confusing you, the table that shows the supporting lab on the kit, not the detailed function on the kit.

    Btw, both the PWMDAC and datalog are just for ease debugging the project, it doesn't affect running the motor as well if you disable both functions in the project.
