INTEGRATION¶
Introduction¶
Note
In this section, we introduce how to integrate the DHT11 driver into the project.
Create a New Component¶
Warning
Before you create a component in the driver directory, make sure you have incorporated the driver directory into the project by adding the path to the driver directory to the EXTRA_COMPONENT_DIRS variable in the project-level CMakeLists.txt file.
Open the project in VSCode, open the integrated terminal, and type in
to actiate the ESP-IDF environment. Then type in the following command to create a new component named node_th_dht11:
The command above means to create a new component named node_th_dht11 in the driver directory. After executing the command, you will see a new directory named node_th_dht11 in the driver directory. And the command will automatically generate the CMakeLists.txt file for the new component, as well as the node_th_dht11.h and node_th_dht11.c files.
Alternatively, you can mannually create the node_th_dht11 directory in the driver directory, and then create the CMakeLists.txt, node_th_dht11.h, and node_th_dht11.c files in the node_th_dht11 directory.
Replace the Code¶
Component Level
Replace the code in this section into the CMakelists.txt, node_th_dht11.h, and node_th_dht11.c files under the component.
Project Level
Replace the code in main.c/cpp with the corresponding code. No need to change the CMakeLists.txt file at the project level.
Compile and Flash the Project¶
Open the project in VSCode, open the integrated terminal, and type in
Then you will see the feedback from the serial monitor.
