代码说明:

 RS485、CAN这类总线型通信方式,由于抗干扰能力强、结构简单、组网方便、实时性好、支持多种现场总线协议,因此被广泛应用于工业现场。但是较低的通信速率、较小的组网规模、繁多的通信接口和通信协议还是限制了总线接口通信的发展进程。本例程主要介绍了通信原理

  • MeshLab_v100_src
    MeshLab is an open source, portable, and extendible system for the processing and editing of unstructured 3D triangular meshes. The system is aimed to help the processing of the typical not-so-small unstructured models arising in 3D scanning, providing a set of tools for editing, cleaning, healing, inspecting, rendering and converting this kind of meshes.(MeshLab is an open source, portable, and extendible system for the processing and ed iting of 3D unstructured triangular meshes.
