Preface We were operating the SPI, but strange phenomena occurred when the SPI speed exceeded 10MHz and the CPOL/CPHA became mismatched. After researching various methods, we found the trick was in the GPIO settings. Here, we provide detailed instructions for setting the GPIO SPEED SETTING to avoid such issues, which is applicable not only to […]

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

QSPI Introduction QSPI stands for Queued Serial Peripheral Interface, an extension of the SPI interface introduced by Motorola. QSPI has wider applications than SPI due to the enhanced functionality provided by Motorola, including the addition of a queued transmission mechanism. This led to the development of the Queued Serial Peripheral Interface Protocol (QSPI protocol) based

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

TouchGFX TouchGFX Key Features TouchGFX provides support for System structure Preparatory work – Installation and Configuration As we are using H750, we will need an external plugin for the flash part, so the initial configuration will be relatively complex. Here, we will directly focus on the memory configuration and provide detailed instructions. Install TouchGFX via

Preface IWDG (Independent watchdog) is used to detect and solve faults caused by software errors. When the counter reaches a given timeout value, it triggers an interrupt or generates a system reset. The independent watchdog clock is its dedicated low-speed clock (LSI), so it can continue to work even if the main clock has problems.

Basic introduction to DMA DMA, short for Direct Memory Access, allows data to be transferred from one address space to another without CPU intervention. It provides high-speed data transfer between external memory or between registers without the need for CPU involvement. DMA transfers can quickly move data without CPU intervention. DMA mapping Since the WB

Preface In MC SDK 5.x, there are two control loops, the current loop and the speed (torque) loop. Some applications require the use of a position loop, such as motor control for UAV gimbal or subway gates. This article will explain how to add a simple position loop on top of the existing ST motor

Preface Sometimes it’s necessary to share a compiled .lib file instead of the C source code when giving others access to your code. So, how can we use CubeIDE to compile a project into a .lib file and then utilize the .lib file? This tutorial will guide you through the process of creating a .lib
