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 When using the ST FOC motor control library with Hall signals as the position feedback, synchronous electrical angle data must be input based on the characteristics of the motor being used. This data synchronizes the electrical angle with the Hall signal at each signal change. If the angle deviation is large, it may affect

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

Preface I2C has two different modes of operation: master and slave mode. In most cases, when controlling sensor MCUs, the master mode is used for operation. Some EEPROMs may require the MCU to operate as a slave. However, when using the slave HAL, a known length is required for normal operation. Here, we will introduce

Preface A position sensor is a sensor that facilitates measurement of mechanical position. The AS5600 is an easy to program magnetic rotary position sensor with a high-resolution 12-bit analog or PWM output. The AS5600 is also equipped with a smart low power mode feature to automatically reduce the power consumption. Design Note The AS5600 has some important hardware setup points. The

Preface The previous post described the main program structure generated by the STM32 Motor Control Workbench. Here we will continue to explain the three core task flows and structures that depend on the main structure, which are mainly divided into three parts: safety tasks, medium frequency tasks, and high frequency tasks. The safety task mainly

Preface Here, there are many online resources available for reference, such as the video tutorials on FOC control principles and motor application development based on STM32. This discussion focuses on the code generated by ST’s Workbench after setting up the parameters, mainly on the program architecture and important code explanations. After understanding the architecture, users

Preface On the ST side, Motor Profiler and MotorControl Workbench are introduced to facilitate the complete construction of the underlying program and provide basic APIs for applications. They are relatively easy to use for beginners and have the advantage of having all their code fully open for viewing, including the writing methods of each API.

Introduction Position Sensor A position sensor is a sensor that facilitates measurement of mechanical position. A position sensor may indicate absolute position (location) or relative position (displacement), in terms of linear travel, rotational angle, or three-dimensional space. Comparison Chart Currently, there are six main types of sensors commonly used for position sensing, including Inductive, Hall Effect, and Magnetic Encoder.
