How to I2C communication method

[y001]

Hi,

I am using fatfs of nRF5_SDK_15.0.0_a53641a.

I am writing a program with keil.

I am currently doing SPI communication with BLENanov2(nRF52832) and SD card with fatfs.

Therefore,BLENanov2 and sensors also want I2C communication.

(I want to write data from sensor to SD card via BLENanov2.)

Do you know sample code for I2C communication?

Currently I am using fatfs, please tell me to write to fatfs if possible.

Thank you!

BLENanov2

It would be helpful to provide a link to this - rather than expect everyone to just know what you're talking about, or to have to google it themselves.

I guess you mean this: https://redbear.cc/product/ble-nano-2.html ?

Is it possible to perform two SPI communications from BLENanov2?

What does its documentation tell you?

The above web page tells you it has an nRF52832

The nRF52832 Product Page is here: https://www.nordicsemi.com/eng/Products/Bluetooth-low-energy/nRF52832

It says, in the list of Features: 

• 3 x Master/Slave SPI

Thank you for reply!

I am sorry for lack of explanation.

It is a product of the street of that link.

It is possible to have three SPI communications!

If you know that there is a code that allows two SPI communications in the SDK,please let me know.

The nRF52 has TWI peripherals (I2C compatible two-wire interface master with EasyDMA). For most intents and purposes TWI == I2C, and there are several TWI samples in the SDK and the TWI drivers are documented here.

IS the forum playing up, or has y001  totally changed the OP ?!

The text which I quoted in my previous reply no longer exists in the OP, and the OP is now all about I2C - not SPI !

I'm Confused!!
