Hardware Overview (2/2)

•The X-CUBE-TOF1 software package is a STM32Cube

expansion for the expansion boards of the Time-of-

Flight product family (including the X-NUCLEO-53L8A1)

for STM32. The source code is based on STM32Cube

to ease portability and code sharing across different

STM32 MCU families. A sample implementation is

available for the STM32 Nucleo ranging sensor

expansion board (X-NUCLEO-53L8A1) plugged on top

of an STM32 Nucleo development board (NUCLEO-

F401RE or NUCLEO-L476RG).

Setup & Demo Examples

SW prerequisites

Setup & Demo Examples

NUCLEO Kit driver installation

1. Connect the P-NUCLEO to the PC through USB

•Wait for the board to be recognized;

the drivers are installed automatically)

•If Windows cannot install automatically the

STLINK driver, please follow step 2

2. Install the PC USB port driver to detect the Nucleo board

•Download STSW-LINK009 from www.st.com

• Unzip and double click on “stlink_winusb_install.bat” to install the driver

Setup & Demo Examples

VL53L8CX GUI software installation

•Perform the offset and Xtalk calibration and visualize calibration data

•Change key parameters of VL53L8CX

•Display real time the data (distance, signal, ambient rate)

•Get data logging and replay a datalog (.csv file)

•Perform HW installation and connect the X-NUCLEO-53L8A1 expansion board + Nucleo F401RE to the PC

•Install the GUI SW for VL53L8CX Demo and configuration settings

•STSW-IMG041, downloaded from www.st.com

•Run the installer with Admin privileges

GUI is generally the first and easy tool to evaluate the device
