Other Parts Discussed in Thread: BQ27Z746, BQSTUDIO
How do I write data into the System Data of the BQ34Z100 and BQ27Z746?
I tried writing, but it was unsuccessful. Are there any additional conditions or requirements for writing?
The attached image is a screenshot I captured from BQStudio.
When I attempted to write, the lower left corner displayed the message: "A read of data written failed comparison."
At the same time, I’ve also attached the data captured using a logic analyzer.
