TI中文支持网Other Parts Discussed in Thread:BQ78Z100
BQ78Z100读电流或电压时，只读2个字节，怎么确定数据是对的呢，有没有校验和什么的机制？
Star Xu：
您好，查到的信息如下：
The bqStudio tool, like (some) other gas gauge tools will use PEC if the address is selected as 17, it will not use PEC if the address is sent as 16. The address on the bus is 0x16 for write, 0x17 for read. These are used regardless of the address selected in the tool window, the address in the tool window just switches the mode of the tool to send and check the extra data or clocks for data. The tool hides the extra protocol, but you can see it with a scope or I presume a protocol analyzer. This could be useful for comparison. This is a tool feature and I presume documented somewhere for the tool, it is not in the TRM since it is a tool feature.
