BQ78350-R1: My C code can not read bq78350 back. Anyone has the driver example?

Other Parts Discussed in Thread: BQ78350, BQ40Z50

I am using the IO to simulate the SMBus communication. But I were fighting with it for three days already, still can not read any register value back -- no any response.

Any body have a example driver for my reference to test? Really appreciate! Thanks!

Hi David,

Thanks. We checked the sequence of the timing, bq78350 ACK after the device address. But no response after that (for the register address....).

We need some code for reference. Thanks for your support!

Hi Sam,

You might be able to find a good example from other users on sites like Github. Here is the link to example code for the BQ40Z50 which also uses SMBus. Hopefully this will be helpful. github.com/.../bq40z50

This app note may also be a good reference to help debug the issue: www.ti.com/.../slua475

Best regards,
Matt

Hi Matt,

Thank you for your support! But there is no low level read and write byte in the bq40z50 sample code.

Anyway, thanks for your slua475. Enjoy your holiday!
