Introduction
This user manual gives an overview of the use of STEVAL-IFS001V1 kit with MEMS (Micro-
Electro-Mechanical System) evaluation board.
As shown in the next section, this evaluation board consists of the DK3420 (uPSD
evaluation board) and the ST-MEMS-xx-EVAL (MEMS evaluation module). When connected
together as an evaluation kit, MEMS applications can be evaluated and measured through a
USB connection to a PC. A brief introduction to the MEMS software, MEMS USB Reader
7.x, is also provided.
MEMS can be used in a variety of vibration sensor and intelligent movement estimator
situations, for example:
■
Vibration analysis
– Motor control
– High buildings
■
Control of position
– Stability system for caravans
– Stability for cable cars
■
Sport
– Sport shoes
– Speedometers
■
Automotive
– Black box
– Intelligent driver sensors
– Car alarms
■
Navigation
– Dead-reckoning for GPS
■
Logistics
– Blackbox for containers (sensoring)
■
Robotics
– Control of robot arms (welding robots)
■
Security
– Vibration detection (broken window alarm)

Page 8: Recommendations For I2C Use
I2C and SPI use STEVAL-IFS001V1 Recommendations for I C use ● With I C, the use of R36 & R37 pull-up resistors (4k7) is advised ● The use of resistor R34 (10k) is not normally necessary as uPSD has an internal pull- up of around 100k. -
Page 9: Upsd Software Use
STEVAL-IFS001V1 uPSD software use uPSD software use Digital or analog module The program automatically detects whether a module is digital or analog. The recognition is based on the value on pin P3.3. A digital module has this pin unconnected which is the same as logic ‘1’ because of an internal uPSD pull-up. Analog modules must employ a pull-down resistor to enable the detection of logic ‘0’. -

STEVAL-IFS001V1 On-line measurement During on-line measurement, data is read from MEMS and sent via USB to the PC. Logically, all three LEDs should blink. In this mode, the buttons have the following meanings: ● no button is pressed uPSD sends data from MEMS to the PC (a packet with MEMS data) ●... - Page 11 STEVAL-IFS001V1 uPSD software use values translate as <-1,-1,-1> readings on the PC MEMS USB Reader, which should be considered to detect both false readings and end of Flash data. ● BUT6 is pressed No effect. ● BUT7 is pressed No effect.
