Original question:

BQ34110: BQ34110

BQ34110: data sheet question

Part Number: BQ34110

Hi Team, 

May I ask the following questions:

1. The internal physical address of BQ34110 should be in 16-bit format. Is the specific address which mentioned in P66 (3.1 Command Summary)?

2. If the communication format of I2C is stated in P64  (2.15 Communications), but CMD[7:0] is only 8-bit address, how should this be operated?

3.In datasheet (2.15 Communications---quick read) . The return value is the value pointed to in the data address pointer, but how to determine the specific address of the data pointer?

4. In datasheet P103 (5.3) the method of factory calibration is given. What do the parameters in I2CWriteWord(0x00, 0x002D, 100) respectively mean? What do 0x00/0x002D/100 mean?

5. I wonder if there are any sample programs for reference in TI for this IC.

Thanks!

    hi Andy,

    Thanks for your reply！

    In order to communicate easier, please see my translate as following：

    Thanks!

    1.BQ34110内部物理地址应该是16位格式，具体的地址是否为P66页，3.1中Command Summary表述

    2.I2C进行通讯时，具体的通讯格式如果按照P64页，2.15Communications中表述，CMD[7:0] 仅仅为8位地址，这个应该如何操作

    3.2.15Communications中表述quick read方式，返回值是数据地址指针中指向的值，但是如何判定具体的数据指针指向何处地址？

    4.在P103页，5.3中给出了工厂校准的方式，请问下I2CWriteWord(0x00, 0x002D, 100)里面的参数分别代表什么意思？

    5.不知此款IC的是否有范例程序可供参考。

    I believe this is a repeat thread. I'm closing this out.
