S32DS don' t has MPC5746R ePTU's SDK.

Hello, everyone
I'm using the S32DS compiler and I didn't find any etPU module in the SDK I used. Can you help me find an SDK with MPC5746R eTPU? Thank QQ图片20200914174123.pngyou.

Hi, eTPU use is different and SDK is not involved. NXP's eTPU libraries you may use with SDK project as well. I am linking example project showing integration of old eTPU functions into S32DS:

Below you may find a general answer introducing use of eTPU:

-----------

eTPU is an complex I/O co-processor. You can use it two ways:

1) with using of eTPU functions prepared by NXP

2) to create your own function or modify NXP’s function

 

Ad 1)

For using eTPU functions pre-prepared by NXP (the ones you can download by eTPU Function Selector) without modification you don’t need any eTPU compiler. See

http://www.nxp.com/webapp/etpu/

 

Also there is some new version, currently containing only some functions:

http://www.nxp.com/webapp/etpu_cw/

 

Only download them, configure by eTPU graphical configuration tool (GCT), include all needed files to CodeWarrior or other compiler and use it.

 

GCT is the tool which is intended to configure most of functions prepared by NXP that can be downloaded as a pack here:

http://www.nxp.com/webapp/sps/download/license.jsp?colCode=ETPUGCT&Parent_nodeId=1311258915317726989...

 

Here you can example procedure how to use eTPU PWM function, step by step:

http://www.nxp.com/files/soft_dev_tools/doc/app_note/AN4687.pdf

 

Every eTPU FUNCTION has its own descriptive documents (application note), its software attachment usually contains some simple example code:

Ad 2)

If you cannot fit our existing eTPU function to your application you can write your own function or modify the existing one you will need eTPU compiler and simulator.

 

Currently there are 2 options (preferred solution is no.1):

1) Ashware solution (compiler + simulator)

2) NXP eTPU2 Development Suite (compiler + simulator)

http://www.nxp.com/products/automotive-products/microcontrollers-and-processors/32-bit-power-archite...

 

Buying of following book could be good start point for developing you own eTPU function or library:
