It's been a little while since I've had these modules on my desk!

I'll see what I can turn up for you.

Tom,
I have few of these modules, how do you access them?
What is the I2C configuration?
I've looked at the board and it looks like it connect to pins 6 & 11, but twi scanner can't find it.

Hi Dariusz,

Pretty much every peripheral I/O (with the exception of the NFC and analog peripheral I/O) can be routed to any of the available pins on the package.

See here for details;

https://devzone.nordicsemi.com/f/nordic-q-a/14055/nrf52-pinout-or-dedicated-pins?ReplyFilter=Answers&ReplySortBy=Answers&ReplySortOrder=Descending

It has been some time since I used the modules, so I do not have the specific configuration to hand for that module I am afraid.

If you are referring to this specifc module, let me know, and I'll dig out my target board and try get some mappings for you!

Hi tom-fleet

Which pins of nrf are used for I2C?

RE: nRF52832 with BMX055

tom-fleet — Wed, 12 Dec 2018 17:51:52 GMT

Hi All,

I just received a few of these modules, and can report that the table above is incorrect.

Pin 7 (PS) of the BMX055 is tied to *ground*, which means the device expects to operate in I2C mode, and should be addressed as such.

I have data streaming from the board, with code based on one of the several BMX055 examples on github.

BR,

Tom

The more interesting thing is how did you write the SPI read/write functions for the BoschSensortec library? The library does not provide these functions for you, as these are platform specific. The file bma2x2_support.c show an example of how to implement this.

Have you implemented your own read/write functions?

Oh sorry, following your question

- I read value by RX and it is -127. I tried to change value of CS pin but it did not work

- value is -127 and never change

- I don't know how to check error codes (I'm newbie :( )

- yes, i did. But can't find anything

- No

Hard to say, I can't see the implementation of read_accel functions in your above code. Please post this code as well, or prefereably upload the entire project. This way we can help you debug the issue.

I would also ask you to answer the rest of the questions from my previous comment.

thanks for reply!

When i call function read accelerometer data, I read value by RX and it is -127. I tried to change value of CS pin but it did not work. Have I wrong something???

RE: nRF52832 with BMX055

Jørgen Holmefjord — Wed, 01 Aug 2018 12:27:54 GMT

You need to provide some more details on what the issue is that just "I can't read data out of BMX055".

What is not working? What have you tried to fix it?
How do you see that you are not able to read any data?
Are you checking error codes returned from all function calls?
Have you tried debugging, to see if any errors are reported?
Have you checked the SPI lines using a logic analyzer, to see if any data is transmitted?
