BME688 sensor API

[Rosso9]

Hi, I'm using  the BME688 sensor for a new project with Nordik nRF52832. I find on github the API for using the sensor. The problem is that API's files include the library coines that I'm not able to find anywhere. I would like to ask you if you have it or if you have a structure of the library to implement (because I do not understand what the various functions do). Thanks for your helps

Here is my answer for below your question. 

coines_config_i2c_bus(COINES_I2C_BUS_0, COINES_I2C_STANDARD_MODE);

- Set I2C communication. This function is to set i2c for our platform. 
coines_set_shuttleboard_vdd_vddio_config(3300, 3300); (both in the interface_init function)

- coines_set_shuttleboard_vdd_vddio_config handles our board power source. In your case, no need to apply. 

coines_soft_reset(); - Please remove it. bme68x_coines_deinit is not necessary for test. 
coines_delay_msec(1000); - mili second delay function. 

Thank you. 
coines_close_comm_intf(COINES_COMM_INTF_USB);

Thanks for helping.

Now I try to adapt the code.

One further question. If I have already initialized the I2C communication in my project (I use it with other sensors), does I need to use this command  coines_config_i2c_bus(COINES_I2C_BUS_0, COINES_I2C_STANDARD_MODE);

or can I avoid it?

No you don't have to do. 

It's our i2c configuration code, so you don't need it 🙂

Thanks again for the answer.

I have a last (I hope) question.

I was looking the API code and I saw that a lot of functions refer to SPI comunication (for example in get_regs function there is a mask called BME68X_SPI_RD_MSK even though in the previous if the condition is I2C interface). I use I2C comunication, does it create a problem?

Thanks again

Hi Rosso, 

You should do use I2C or SPI without any problem in BME688 API. 

All SPI functions should be called only if you select BME68X_SPI_INTF. 

Please let me know if you have any questions. 

Thank you.
