BMP388 MULTIPLE DEVICES USING SAME SPI BUS

[BSTRobin]

Hello Honoju,

Please check sensor power supply (current/voltage), record the waveform by oscilloscope or logic analyzer.

And let us know your check result.

Hello Honoju,

Have you tried to check it?

Hello BSTRobin,

Sorry for the long time with no response, I have been away from work.

We recently acquired a regulated voltage supply, I'm going to try it and get back to you when it is done.

Regards,

Hello BSTRobin,

We are now considering designing our own PCBs to overcome the failure.

Thanks for your help,

Hello Honoju,

Okay.

In the new hardware design, the SPI line should be as short as possible, and the power supply should be enough.
