Working modes
The STEVAL-MKI0xxV1 demonstration board is designed to be used in two different
working modes:
- Analog working mode (AWM): the microcontroller on the board is disabled and the analog
outputs of the device are available to the user on the dedicated connector
This is the default working mode when power is applied either through the USB connector or
through the supply connector
-Digital working mode (DWM): the microcontroller on the board is enabled and allows the
user to digitally acquire the output signals of the device, to see them on the PC through the
dedicated GUI and to manage the control pins of the device.
Each working mode requires a board setup, which is done by correctly setting the jumpers
labeled JP4, JP5, JP7 (see ref 1, ref 2 and ref 3, respectively, in
labeled JP1 and JP6 (see ref 4 and ref 5, respectively, in
Analog working mode (AWM)
AWM is the working mode activated by default when the board is connected to a PC by USB
or when the power supply is applied to J10. The microcontroller on the board is disabled and
board behavior can be controlled through the dedicated jumpers.
In this working mode, the power down (PD), self-test (ST) and high-pass filter reset (HP)
functions are respectively managed by JP4, JP5 and JP7 as described below (see
to identify the jumpers):
Table 1.
Analog output signals can be measured respectively through pin 3 (marked Out1), pin 4
(marked Out2, for single-axis devices only) and pin1 (GND) of the J3 header (see
ref 7).
The JP1 and JP6 jumpers allow the user to select which output signal is available on J3.
