Introduction The VL53L5CX system consists of a hardware module and an ULD software (VL53L5CX ULD) running on the host. The hardware module contains a Time-of-Flight (ToF) sensor. ST provides a software driver, referred to as the “driver” in this document, which describes the functions of the driver that the host can access. These functions control

Preface In this article, we will explain how to use the CDC (Communication Device Class) in USB to create a virtual COM port (VCP) for communication. On the one hand, for the host computer, it appears as a serial port, and all operations are still based on serial port operations. On the other hand, the

Preface Currently, ST has two sets of USB drivers. One is the early independent version USB driver, referred to as the Legacy library in official training materials. The other is the driver for its Cube series, which may vary depending on the chip used. Please refer to the corresponding Cube driver package for the specific

一、introduction 1、Principle We use a 940nm Vertical-Cavity Surface-Emitting Laser (VCSEL) to emit laser light, which reflects back when it hits an obstacle and is then received by the VL53L0X. The time it takes for the laser to travel in air is measured to obtain the distance. Knowledge about VCSEL. 2、Parameter 二、HW Connection layout, I2C lines

An Introduction to USB-HID A Descriptor is a complete data structure that can be implemented through programming languages such as C, and stored in a USB device. It is used to describe all the attributes of a USB device, and the USB host requests this information through a series of commands. There are 5 standard

FreeRTOS Architecture Official website：http://www.freertos.org/FreeRTOS is a relatively small operating system compared to other operating systems. The minimal FreeRTOS core includes only 3 .c files (tasks.c, queue.c, list.c) and a few header files, totaling less than 9,000 lines of code, including comments and blank lines. A typical compiled binary is less than 10 KB. The FreeRTOS
