|
Overview
|
||
|
|
********
|
||
|
|
The X-NUCLEO-IKS01A3 is a motion MEMS and environmental sensor expansion board
|
||
|
|
for the STM32 Nucleo. It is equipped with Arduino UNO R3 connector layout, and
|
||
|
|
is designed around the LSM6DSO 3D accelerometer and 3D gyroscope, the LIS2MDL
|
||
|
|
3-axis magnetometer, the LIS2DW12 3-axis accelerometer, the HTS221 humidity and
|
||
|
|
temperature sensor, the LPS22HH pressure sensor, and the STTS751 temperature sensor.
|
||
|
|
|
||
|
|
The X-NUCLEO-IKS01A3 interfaces with the STM32 microcontroller via the I2C pin,
|
||
|
|
and it is possible to change the default I2C port.

Hardware Configuration
|
||
|
|
**********************
|
||
|
|
|
||
|
|
X-NUCLEO-IKS01A3 board connects the various devices on two separate I2C bus:
|
||
|
|
|
||
|
|
- LIS2DW12 and LSM6DO are on I2C2
|
||
|
|
- LIS2MDL, LPS22HH, HTS221 are STTS751 are on I2C1
|
||
|
|
|
||
|
|
X-NUCLEO-IKS01A3 board can be configured in two different ways: Mode 1 and Mode 2
|
||
|
|
|
||
|
|
|
||
|
|
Mode 1: Standard Mode
|
||
|
|
=====================
|
||
|
|
|
||
|
|
In standard I2C mode the two buses are connected together. As a consequence, all devices on the shield
|
||
|
|
reside on the same I2C bus and are accessible from the main board thru I2C bus.
|
||
|
|
|
||
|
|
The jumper configuration to activate this mode is:
|
||
|
|
|
||
|
|
- JP7 => 1-2, 3-4 (I2C1 = I2C2, I2Cx=GND)
|
||
|
|
- JP8 => 1-2, 3-4 (I2C1 = I2C2, I2Cx=GND)
|
||
|
|
|
||
|
|
|
||
|
|
Mode 2: SensorHub Mode
|
||
|
|
======================
|
||
|
|
|
||
|
|
In SensorHub mode LSM6DSO and LIS2DW12 are connected to I2C2 and are accessible from the main board.
|
||
|
|
All the other devices are connected to LSM6DSO master thru I2C1.
|
||
|
|
|
||
|
|
The jumper configuration to activate this mode is:
|
||
|
|
|
||
|
|
- JP7 => 2-3 (I2C1 = I2Cx)
|
||
|
|
- JP8 => 2-3 (I2C1 = I2Cx)
|
||
|
|
|
||
|
|
