STMicroelectronics EK3LV02DL

Overview

EK3LV02DL from STMicroelectronics is an evaluation kit designed to enable rapid functional validation and interface development for the LIS3LV02DL - a low-power, 3-axis digital-output MEMS accelerometer with SPI interface, ±2g/±6g selectable full-scale range, and integrated self-test and high-pass filter. The kit includes the sensor mounted on a PCB alongside an ST7-USB microcontroller acting as a USB-to-SPI bridge, enabling real-time register access, direction detection, and continuous acceleration data acquisition up to 640 Hz via virtual COM port.

For engineers reviewing the EK3LV02DL datasheet, EK3LV02DL pinout, EK3LV02DL application, or EK3LV02DL equivalent, this kit supports hands-on evaluation of motion-triggered interrupt behavior, tilt-based UI control, MEMS pointer implementation, and embedded system integration with Windows XP–based host software and GUI tools.

Technical Context

The EK3LV02DL implements a hardware-software co-design: the LIS3LV02DL MEMS sensor provides configurable ODR (1Hz–640Hz), programmable thresholds for direction detection, and self-test activation via dedicated registers; the ST7-USB MCU handles USB enumeration, SPI transaction translation, and firmware-level command parsing (e.g., Start, Debug, Registers Read/Write, Zon/Zoff).

It delivers real-time acceleration data in 12-bit resolution per axis, supports both single-shot and continuous acquisition modes, and enables gravity-compensated orientation sensing via its onboard high-pass filter - all accessible through a Windows GUI that maps physical board axes (X/Y/Z) to visual plots, bar charts, inclinometer displays, and map browsing demos.

FAQ

What operating systems does the EK3LV02DL GUI support?

The official EK3LV02DL Graphical User Interface requires Microsoft Windows XP (SP1 or later) and Microsoft .NET Framework 1.1 or higher. It is not compatible with Windows Vista or newer OS versions due to driver architecture changes and discontinued Virtual COM support for the ST7-USB firmware stack.

Does the EK3LV02DL include the LIS3LV02DL sensor?

Yes - the EK3LV02DL evaluation board integrates one LIS3LV02DL 3-axis accelerometer as its primary sensing element, mounted with defined X/Y/Z axis orientation per Figure 16 in UM0285, and directly connected to the ST7-USB microcontroller via SPI bus.

Can I use the EK3LV02DL without the provided GUI?

Yes - the board responds to ASCII-based serial commands (e.g., "Start", "Registers read", "Zon") over the Virtual COM port, allowing custom host software to perform register access, data acquisition, and direction detection control without the ST GUI.

Is the ST7-USB microcontroller reprogrammable?

No - the ST7-USB firmware is pre-flashed and locked; it functions exclusively as a USB-to-SPI bridge with fixed command protocol. ST does not provide source code, debug interfaces, or programming headers for user firmware modification on this evaluation kit.
