Changes To Accommodate Esp-idf V5

by ADMIN 34 views

Introduction

The ESP-IDF (Espressif IoT Development Framework) is a popular open-source framework for developing IoT applications on ESP32 and ESP8266 microcontrollers. With the release of ESP-IDF v5, several changes have been introduced to improve the framework's stability, security, and performance. However, these changes also require modifications to existing components to ensure compatibility. In this article, we will discuss the changes required to accommodate ESP-IDF v5 in the esp32-rotary-encoder-example component.

Unsupported Component

The esp32-rotary-encoder-example component does not support ESP-IDF V5. To resolve this issue, we need to modify the CMakeLists.txt file in the esp32-rotary-encoder-example/components/esp32-rotary-encoder directory.

Modifying CMakeLists.txt

The CMakeLists.txt file is used to configure the build process for the component. To modify it for ESP-IDF v5, we need to update the following lines:

idf_component_register(SRCS "rotary_encoder.c" INCLUDE_DIRS include PRIV_REQUIRES driver)

#set(COMPONENT_ADD_INCLUDEDIRS include)
#set(COMPONENT_SRCS "rotary_encoder.c")
#register_component()

We need to remove the commented lines and update the idf_component_register function to include the PRIV_REQUIRES option. The updated code should look like this:

idf_component_register(SRCS "rotary_encoder.c" INCLUDE_DIRS include PRIV_REQUIRES driver)

GPIO Configuration Changes

In addition to modifying the CMakeLists.txt file, we also need to update the GPIO configuration code to accommodate the changes introduced in ESP-IDF v5. Specifically, we need to replace the gpio_pad_select_gpio function with gpio_reset_pin.

Updated GPIO Configuration Code

The original GPIO configuration code looked like this:

// configure GPIOs
//gpio_pad_select_gpio(info->pin_a);
gpio_pad_select_gpio(info->pin_a);
gpio_set_pull_mode(info->pin_a, GPIO_PULLUP_ONLY);
gpio_set_direction(info->pin_a, GPIO_MODE_INPUT);
gpio_set_intr_type(info->pin_a, GPIO_INTR_ANYEDGE);

//gpio_pad_select_gpio(info->pin_b);
gpio_pad_select_gpio(info->pin_b);
gpio_set_pull_mode(info->pin_b, GPIO_PULLUP_ONLY);
gpio_set_direction(info->pin_b, GPIO_MODE_INPUT);
gpio_set_intr_type(info->pin_b, GPIO_INTR_ANYEDGE);

We need to update this code to use gpio_reset_pin instead of gpio_pad_select_gpio. The updated code should look like this:

// configure GPIOs
gpio_reset_pin(info->pin_a);
gpio_set_pull_mode(info->pin_a, GPIO_PULLUP_ONLY);
gpio_set_direction(info->pin_a, GPIO_MODE_INPUT);
gpio_set_intr_type(info->pin_a, GPIO_INTR_ANYEDGE);

gpio_reset_pin(info->pin_b);
gpio_set_pull_mode(info->pin_b, GPIO_PULLUP_ONLY);
gpio_set_direction(info->pin_b, GPIO_MODE_INPUT);
gpio_set_intr_type(info->pin_b, GPIO_INTR_ANYEDGE);

Conclusion

In conclusion, to accommodate ESP-IDF v5, we need to modify the CMakeLists.txt file and update the GPIO configuration code. By making these changes, we can ensure that the esp32-rotary-encoder-example component is compatible with ESP-IDF v5. We hope that this article has provided you with the necessary information to make these changes and get your component up and running with ESP-IDF v5.
