MSPM0G3507: When to use DL_DAC12_startCalibration()?

Part Number: MSPM0G3507
Other Parts Discussed in Thread: SYSCONFIG

Tool/software:

Hi Champs,

I am asking this for our customer.

1. Does TI boot code use DL_DAC12_startCalibration()?

2. Does the user need to do DL_DAC12_startCalibration()?

If yes, when should the user use it?

3. Will Sysconfig for DAC12 uses it by default?

    Hi Wayne,

    1) The device does not automatically run this function while starting up, you must call it manually. The devices are already trimmed / calibrated when we manufacture them so calibrating each time on start-up is not necessary.

    2) The user only needs to use this if they want to perform their own calibration. This is described in section 14.2.11 in the device's technical reference manual. So a user does not need to use this function just because they are using the DAC.

    3) Sysconfig does not use it by default. The user would need to call this function manually. You can see the code that Sysconfig generates to check something like this by clicking the "<>" symbol in the top right of the sysconfig window. Then you can select the files and view the code. If you do this after adding the DAC12 you can see that this function is not called by the sysconfig generated code.
