under boards/arm/pinetime are the board definitions
- pinetime.dts
- pinetime_defconfig
The sensors in the pinetime use the I2C bus.
&i2c1 {
compatible = "nordic,nrf-twi";
status = "okay";
sda-pin = <6>;
scl-pin = <7>;
};
In the directory of a sample, you will find a prj.conf file. Here you can set values specific for you project/sample.
In the "prj.conf" file we define the sensor (eg adxl372)
CONFIG_STDOUT_CONSOLE=y
CONFIG_LOG=y
CONFIG_I2C=y
CONFIG_SENSOR=y
CONFIG_ADXL372=y
CONFIG_ADXL372_I2C=y
CONFIG_SENSOR_LOG_LEVEL_WRN=y
note: this gets somehow merged (overlayed) with the board definition pinetime_defconfig
