The PWM output mode of GD32F4xx controls the transformation of the lamp

Introduction to PWM principle PWM basics 1. Introduction to PWM PWM (Pulse Width Modulation) is a very effective technology that uses the digital output of a microprocessor to control an analog circuit. PWM is a method of digitally encoding the level of an analog signal. Through the use of high-resolution counters, the square wave duty […]

Voxelization of 3D CAD models

Have you searched how to convert a Cad model to a python ready numpy array but didn’t get any clear answer? Me too. After long research and trying a lot of software and python libraries, I was finally able to convert a 3D STEP file into a 3D numpy array. If you want to do […]

Example explanation of redis using pipeline mode to write performance tuning under Java Springboot

Instance of redis write pipeline mode performance tuning under Springboot 1. Real scene In the process of producing real projects, it is necessary to write the data of the database to redis synchronously, and encounter the bottleneck of writing to redis during this process. Every time the project is started, the database data must be […]
