MC33774ASP1AE & S32K311NHT0MPAST Interfacing example code with SPI

db_1008 — Sat, 14 Sep 2024 10:34:19 GMT

For 18 cell Lithium Ion BMS , using MC33774ASP1AE & S32K311NHT0MPAST . Is there any example code of interfacing the MCU with AFE on SPI?

Found this MC33774A Communication - NXP Community, but its on S32K344, is there any example code for testing on MC33774ASP1AE & S32K311NHT0MPAST ?

Dear Deepak,

We currently do not have examples for the S32K311 direct SPI with the MC33774A. At this time, our evaluation boards do not support direct SPI communication with the MCU. This boards with MC33774A are designed exclusively for TPL (isolated daisy chain) communication and cannot be used for SPI communication.
To interface between SPI and TPL, a gateway such as the FRDM665SPIEVB is required. Unfortunately, the software for direct communication between the S32K311 and the MC33774A have not been developed.

I apologize for any inconvenience.

With Best Regards,

Jozef

Dear Jozef,

Thanks for info.

I could see one reply on this post with code attachement : MC33774A Communication - NXP Community

Is it removed, or did it had any bug in it?

Dear Deepak,

I don't see any answer either in the MC33774A Communication - NXP Community. It was probably removed.

With Best Regards,

Jozef
