UM11310 ( MC33771C) Simulink TPL Connection

Hi .

I have device RD33771CNTREVM (UM11310) . I'm working from simulink for this device. Since there is no MC33771C support in Simulink tools, I applied the special code adding method.

https://community.nxp.com/t5/NXP-Model-Based-Design-Tools/How-to-use-your-own-C-code-in-our-Toolbox-Battery-Management/ta-p/1119004

I want to establish a TPL connection.

I tried many times but still couldn't communicate with MC33771C.

I made the LSPI settings according to here. :

https://community.nxp.com/t5/NXP-Model-Based-Design-Tools/Battery-measurements-with-Simulink-on-UM11310-HV-BMS/m-p/1179620#M5290

I don't think these settings are suitable for me. (bcc peripheries.h)

Where am I doing wrong. How should the settings be?

Hello @MuhammedAhmet

At first sight, it looks that you are on the right track. You have enabled two SPI instances and yes, you have to modify the bcc_peripheries for the driver to call the instances/ chip selects you use for the board.

More than that, the article How-to-use-your-own-C-code... is handling the MC3377xB which has a different driver and different settings than the ones for the MC3377xC. So you need to use also the driver from here: EMBEDDED-SW-MC33771C

What setup are you using? the one from the UM11310?
