Interfacing MC33771B with Arduino UNO using SPI

ashutosh_saxena — Wed, 09 Nov 2022 04:17:13 GMT

I want help with interfacing MC33771B with Arduino UNO using SPI communication. I am trying to receive the cell values of my battery pack, but I am unable to do so. Can anyone help me with example codes or if someone has already worked on the same, can you please share the code.

Our company has signed NDA with NXP earlier.

We have already downloaded BCC driver software and it is not helping us to establish SPI communication/ fetch data.

You can try to directly download it!

The examples given in the BCC driver folder are for NXP MCU and NXP AFE. I want to configure NXP AFE (MC33771B) with Arduino UNO.

If I have S32K144 evaluation board, will I be able to establish SPI successfully? Is it the same programming that is available in S32 DS ARM IDE.

It shows Arduino as an option in Eval GUI, but it is not selectable. How can I solve this?

You can try to re-set the jumper in the FRDM33771BSPIEVB.

Tried that multiple times, but it is not acknowledging Arduino even after updating the port in device manager.

What's your control board? KL25Z? S32?

As of now I am using Arduino as control board and MC33771B as AFE (Cell controller).

You can refer to below picture showed code, this GUI design based on KL25Z.
