Embedded SW: Battery Cell Controller Software Driver for MC33771B/MC33772B

EMBEDDED-SW-BCC

This embedded software solution provides high-level support for listed NXP analog parts (MC33771B and MC33772B).

Included embedded driver provides access to all features of Battery Cell Controllers such as writing/reading registers, configuring daisy chains, handling faults, doing diagnostics and measuring voltage, current and temperature.

Implementation of the BCC software driver is generic, allowing to use any suitable 32-bit microcontroller with SPI modules and enough number of GPIO pins. Example projects for S32K144 microcontroller are part of the package.

There are two packages with BCC SW driver available: Full version and Lite version. Lite version is available directly from nxp.com web pages (without NDA required) but does not provide an implementation of diagnostic functions.
