  • Programming system for device control
    Patent number: 10095209
    Abstract: A programming system for device control is disclosed. The system includes a development board scanning module, a web server, and a working host. An application programming interface packaging module in the working host is a key part to translate high-level programming language codes into low-level programming language codes. Thus, using high-level programming language or interface to implement equipment control or development work becomes feasible.
