From 8f98839255b6bdccd21610454818b0d75e40414e Mon Sep 17 00:00:00 2001 From: Tomasz Michalec Date: Wed, 19 May 2021 17:00:33 +0200 Subject: zephyr: Add BMA255 emulator Add BMA255 emulator which is emulated device on i2c bus. Emulated accelerometer properties are defined through device tree, but they can be changed in runtime through BMA255 emulator API. It allows to set custom handlers for write and read messages to emulate more complex scenarios or malfunctioning device.
