Hi Team,

BQ27621_RS_Battery.xls

With using EVM, set up the battery parameter as attached Excel file.

then I export dolden image and use this file on sample board, it happened data error from 30 row(C: AA 60 E5)

Q1) Can you share the reference code?

Q2) do we have to input delay time(200ms)? data writing time is so long.

Q3) Can you check the source code as below?

Please use the delays (X: commands) that are embedded in the gm.fs file.
We will release an applications note with reference code this month but it is not available yet.

Hi Dominik

delay term must use at code. Am I correct?
Can you check the C source as attacehd before thred?
Also Can you share the reference code by mail earlier? Please review the attached Source code

Especially, below part has error.

Something seems to go wrong with the check-sum.

I recommend the following:

* read the whole subclass data block (32 bytes) into a buffer
* change the parameters that you want to update in this buffer
* calculate the check-sum for the whole 32 byte buffer
* write the whole subclass data block
* write the check-sum
* wait
* verify the check-sum

Hi Dominik,

I have additional questions.

After POR(power on reset), how much time does need it to control data memory?

Or simply, SET_CFGUPDATE -> read flags register -> set "1" for CONFIG UPDATE bit -> to control data memory ?

BRs,

Nate

Nate,

After POR, wait for the INITCOMP bit (7) in CONTROL_STATUS. Once this is set you can start updating the data memory.

Regards,
Dominik.

Hi Dominik,

Very thanks

I have 2 more questions.

Q1) In quickstart guide, there is commented 100ms delay time at flowchart. Can it changed to 10ms?

what is minimum delay time?

Q2) For BlockData() writing, we have to 32-byte. As below, Can I delete data written 00 ?

For example, yellow row - After AA 40, there is 32 byte data. just write 02 26 00 00 32 then after date is deleted.

To do this question, I try to reduce checksum time.

A1: Please use the X:10 delays from the FlashStream file
A2: This is possible if the previous data in this subclass is all zero. Otherwise the check-sum isn't correct (you have to calculate the check sum of the whole 32-byte block).
