Other Parts Discussed in Thread: BQSTUDIO
目前在熟悉和学习,有两个问题:
1.BQstudio 软件,data memory的设置界面,有不同的项目和参数可以配置,但后面的单位和注释有多个,我想了解最后一列的“native units”和前面的unit单位有何区别,以及设计参数,我该以哪个为准;截图如下:
2.部分单位bq studio软件和文档不符,以哪个为准?
3.部分单位bq studio软件和文档不符2,以哪个为准?

您好,设计以native unite为准,比如shutdown voltage BQSTUDIO显示的是x10 以后的值。
If you enable the advanced views in BQStudio you will see both the value and units displayed (default 6000 mV) as well as the physical address, data length, row, offset and the native units which are 10 mV. If you take the 0x9241 physical address and read it in the bq769x2 Command Sequence window from a default part you get back 0x0258 or 600.

您好,The issue here is that BQStudio is displaying the value in mV, but the real units are in 2mV steps. So if you want a value of "5" which is 10mV, you just type in 10 in the BQStudio Data Memory window and it automatically writes "5" to the device.
For example, I write 10 mV to the Data Memory Window and then read the actual register value from the Command Sequence Window below. You can see the actual value in the register is "5".
There are multiple parameters like this where BQStudio tries to be user friendly. The CC Gain and Capacity Gain parameters for example. You can export a hex dump file if you want to see the actual bits written in data memory.
