This embedded software solution provides high-level support for MC33771C and MC33772C .

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.
