Product overview
Description
The STSW-IMG043 is the software package of the VL53L7CH and the VL53L8CH. The CNH innovative data output is specially designed for AI applications requiring multizone, raw data from a high performance, multizone, ToF sensor.
The same, unique software package supports both sensors. The software includes a complete development ecosystem with drivers, intuitive GUI, and basic Python scripts that give reduced design times. An STM32 project source code running on the STM32F401 completes the software package. A Linux driver can be used in the user space or kernel thanks to compilation keys.
The IR signal measured in each zone is sent as raw data to the host through each bin of the histogram. Highly configurable, the user can program the resolution of the sensors in up to 64 zones (8x8 zones). It is also possible to define the bin width, and modify the histogram resolution in up to 128 bins. All CNH data and standard ToF sensor data (ranging distance, signal level, and reflectance) are transmitted to the host at speeds of up to 30 Hz. Transmission is through I²C in the VL53L7CH, and through SPI in the VL53L8CH.
The CNH data transform the STMicroelectronics' ToF ranging sensor into a versatile optical sensor. This development enables endless AI-based applications. The ability to send both CNH raw data and standard ranging data to the host, opens the door to many new applications beyond simple distance measurements. From solid material (including carpet, wood, glass, and mirror) to gas or liquid (water, oil, and chemicals), it becomes possible to sense the floor material for robotics, to detect the location and size of a cup in a coffee machine, and to develop advanced shape, motion, or hand posture recognition.
