When sending any command using SPI, the data read is 0x8500. Why is this?

Hi 富豪,

 

Refer to datasheet:

0x8500 means no error if you are in reset state.

Please check if you are in reset state according to datasheet 20.

Thanks,

Xiangrui

Thank you very much for your reply.

The problem with SPI has been resolved

I have another problem now: I can output the current normally, but I want to read the current value, and the value I read is always zero, which is why?

I look forward to your reply.

Hi Fuhao,

Thanks for the question. 

But it's better to create a new discussion for current sensing. 

And please check and provide your schematic (refer to figure 21) and current supervision steps, i.e input and output SPI commands (refer to figure 22) in new discussion, if needed.

Thanks,

Xiangrui
