Link IoT Edge provides SDKs for the C, Node.js, and Python programming languages. These SDKs allow you to develop custom drivers to connect devices. The SDKs are known as Link Edge Device Access (LEDA) SDKs. An example is used to describe how to develop a custom driver. In this example, a custom driver is developed to connect an LED lamp to Link IoT Edge.
The available official drivers cannot connect the LED lamp to Link IoT Edge. Therefore, a custom driver must be developed.
The following topics describe how to use the SDK for the C programming language to develop the custom driver.
