How to connect temperature sensor to NRF52832 via i2c

[asabuncuoglu13]

Hello,

Here is a newbie question:

I have NRF52832 (sparkfun breakout board) and ADT7410 temperature sensor and, I want to create a data logger. But, i could not understand how to use i2c interface. I think we will assign the pins manually, but I could not understand how to assign them or use them.

Thank you for your help

Hello asabuncuoglu13

You can find examples of how to use the I2C by looking at the TWI examples that comes with the SDK. You can find these in the [SDK Folder]\examples\peripheral folder. Description of the SDK13 examples can be found at the infocenter here.

The choice of pins is made when the TWI is initialized, where a config variable of type nrf_drv_twi_config_t is created. Here you have the .scl and .sda variables which will contain your pin numbers.

Best regards
