JLed ESP-IDF example (ESP32)

This example shows how to use the embedded JLed library with the ESP-IDF framework.

#include <jled.h>

extern "C" void app_main(void);

void app_main(void)
{
    auto led = JLed(LED_PIN).Breathe(1500).Forever();

    while(1) {
        led.Update();
    }
}

Project Structure

• main/ - example sketch with the program entry point
• components/ - Library dependencies - contains JLed as git submodule
• build/ - build artefacts

Build

• Prerequisite: install and activate ESP-IDF SDK from https://github.com/espressif/esp-idf
• make sure to check out this repo with submodules by using e.g. git clone --recursive https://github.com/jandelgado/jled-esp-idf-example
• Inspect the CMakeLists.txt file and adjust the LED_PIN #define to your needs (GPIO where a LED is connected, e.g. 2 for the builtin LED of the ESP-WROOM-32 board).

The following commands are used to configure, build and flash the image:

• run idf.py build to compile the example
• run idf.py flash to flash the example on an ESP32
• optionally run idf.py menuconfig to configure the image (see (sdkconfig)[sdkconfig])
• run idf.py clean to clean up intermediary files
