Hello everyone,
I have an X-NUCLEO-IKS4A1 expansion board connected to the STM32F401RE Nucleo board. The LIS2DUXS12 sensor on the expansion board incorporates a Qvar sensor capable of detecting changes in electrical charge near the external electrodes connected to the device. I have a detachable STEVAL-MKE001A board connected to the 2 x Header 3pin SMD for QVAR electrode.
To activate the Qvar channel I set the AH_QVAR_EN bit to 1 in the AH_QVAR_CFG register (31h) and I set the INT1_ON_RES bit to 1 in the CTRL1 register (10h) so that the INT1 and INT2 pins are used to connect the electrodes to detect the Qvar signal.
The problem is that the signal I read does not vary when I touch the electrodes as it happens when the LSM6DSV16X sensor as Qvar controller.
Did I skip any steps by chance? It looks like the INT1 and INT2 pins of the sensor are not connected to QVAR1 and QVAR2
