Temperature and pressure sensors BMP085 and BMP180
Connection
The sensors are connected to the hardware I2C bus ([UEXT1 connector]) to use the Wiren Board Smart Home 3.5 controller. The Pinout of the connector UEXT: http://en.wikipedia.org/wiki/UEXT
Configuring the hardware I2C bus
Find the section with the comment: /* uncomment do not enable hardware with I2C */
/* Uncomment no enable hardware i2c */
/*
i2c0: i2c@80058000 {
pinctrl-names = "default";
pinctrl-0 = <&i2c0_pins_a>;
status = "okay";
};
*/
uncomment:
/* Uncomment no enable hardware i2c */
i2c0: i2c@80058000 {
pinctrl-names = "default";
pinctrl-0 = <&i2c0_pins_a>;
status = "okay";
};
In addition, make sure that the list of pinctrl@80018000 pinctrl-0 does not refer to I2C:
pinctrl@80018000 {
pinctrl-names = "default";
pinctrl-0 = <&hog_pins_a
&pin_gpio_pu_0_5
&pin_gpio_pu_0_6
&pin_gpio_pu_0_7
&pin_gpio_pu_0_16
