Looking for an L9963E C STM32 Library

[antonio_capone]

Hi everyone,

I'm currently working on a project where I need to interface an STM32 with the L9963E BMS IC from ST. Before developing my own driver, I wanted to check if anyone has already written a C library for this IC and would be willing to share it or provide some guidance.

If you have experience with the L9963E and have developed a driver, I'd appreciate any insights, code references, or suggestions you can provide.

Thanks in advance!

Hi Andrew,

I have already seen this page. The evaluation board's firmware source code is not provided.

The L9963E is an automotive device whose software is usually only available from your local distributor or STMicroelectronics office.

Hope that helps?

Regards

I am developing a dedicated application in which I need to interface an STM32 microcontroller with the L9963 integrated circuit. The IC datasheet is very clear on how to use/program it and therefore I was looking for an already developed (and maybe open source) driver for STM32. Thank you anyway for the reply.

I’m closing this thread as I’ve decided to develop my own open-source driver, that will be accessible from https://github.com/antoniocapone/l9963-open . For reference, there is also an existing driver that supports the use of the L9963T transceiver (and for now it works only with the transceiver), https://github.com/squadracorsepolito/L9963E_lib.

Special thanks to every people that answered to my question.
