- Basic Example:
ADF defines a series of common display patterns from a functional point of view. In different hardware environments, you can use the interface display_service_set_pattern to set display patterns. Currently, ADF allows you to drive LEDs with PWM, AW2013, IS3x, and WS2812.
This example demonstrates how to set LED mode and checks whether all LEDs are working properly. For more information, please refer to ADF Get Started.
This example runs on the boards that are marked with a green checkbox in the table. Please remember to select the board in menuconfig as discussed in Section Configuration below.
This example supports IDF release/v5.3 and later branches. By default, it runs on ADF's built-in branch $ADF_PATH/esp-idf.
The default board for this example is ESP32-Lyrat V4.3. If you need to run this example on other development boards, select the board in menuconfig, such as ESP32-Lyrat-Mini V1.1.
menuconfig > Audio HAL > ESP32-Lyrat-Mini V1.1Build the project and flash it to the board, then run monitor tool to view serial output (replace PORT with your board's serial port name):
idf.py -p PORT flash monitorTo exit the serial monitor, type Ctrl-].
See ESP-IDF Programming Guide for full steps to configure and build an ESP-IDF project.
After the example starts to run, the LEDs loop through different display patterns in order. The log is as follows:
