SPC5643L question summary

yulong — Mon, 23 Oct 2023 03:46:03 GMT

Hi NXP team，

I have some question about SPC5643L

I use CW 10.6，Matlab 2015a, use MBD but not NXP MBDT

At present, my operation efficiency is much lower than the previous scheme, so I have several questions to confirm

1.I need to use single precision floating-point, is my setting optimal? Do you need to set up floating point libraries elsewhere

My setting：C/C++ Build ->Settings-> Floating Point->SPFP_Only

2.Do you have a CW version of the PWM triggered AD DMA collection routine

3.I use Matlab 2015a, Can I use NXP MBDT? Is this a free tool? Is there a version of SPC5643L for my version?

Hello,

1.I need to use single precision floating-point, is my setting optimal? Do you need to set up floating point libraries elsewhere

My setting：C/C++ Build ->Settings-> Floating Point->SPFP_Only

See following thread:

https://community.nxp.com/t5/CodeWarrior-Development-Tools/enable-floating-point/m-p/462312

2.Do you have a CW version of the PWM triggered AD DMA collection routine

If you are asking about example code. Then I do not find any for such scenario.

3.I use Matlab 2015a, Can I use NXP MBDT? Is this a free tool? Is there a version of SPC5643L for my version?

I dont think you can use it with v 2015a. But you can have a look at release notes of MDBT.

In case you wont find information in release note, please rise a question on MDBT forum, they could give you the most accurate answer.

Yes, it is free of charge.
