Tomasz Bursztyka e18fcbba5a device: Const-ify all device driver instance pointers Now that device_api attribute is unmodified at runtime, as well as all the other attributes, it is possible to switch all device driver instance to be constant. A coccinelle rule is used for this: @r_const_dev_1 disable optional_qualifier @ @@ -struct device * +const struct device * @r_const_dev_2 disable optional_qualifier @ @@ -struct device * const +const struct device * Fixes #27399 Signed-off-by: Tomasz Bursztyka <tomasz.bursztyka@linux.intel.com>		2020-09-02 13:48:13 +02:00

MS5837 Sensor Sample
####################

Overview
********

This sample application retrieves the pressure and temperature from a MS5837
sensor every 10 seconds, and prints this information to the UART console.

Requirements
************

- `nRF52840 Preview development kit`_
- MS5837 sensor

Wiring
******

The nrf52840 Preview development kit should be connected as follows to the
MS5837 sensor.
