INTEGRATION¶

Introduction¶

Note

In this section, we introduce how to integrate the timer 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

get_idf

to activate the ESP-IDF environment. Then type in the following command to create a new component named node_timer:

idf.py -C driver create-component node_timer

The command above means to create a new component named node_timer in the driver directory. After executing the command, you will see a new directory named node_timer in the driver directory. And the command will automatically generate the CMakeLists.txt file for the new component, as well as the node_timer.h and node_timer.c files.

Alternatively, you can manually create the node_timer directory in the driver directory, and then create the CMakeLists.txt, node_timer.h, and node_timer.c files in the node_timer directory.

Replace the Code¶

Component Level

Replace the code in this section into the CMakeLists.txt, node_timer.h, and node_timer.c files under the component.

Project Level

Replace the code in main.c or main.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

idf.py build flash monitor

Now, you will see the LED blinks at the interval of 1s, which is set by the timer period.
