TLE92466ED ESP-IDF Component

This directory contains the ESP-IDF component configuration for the TLE92466ED driver.

Overview

This component wraps the TLE92466ED driver for use as an ESP-IDF managed component, making it easy to integrate into ESP32 projects.

How It Works

Component Resolution

The component automatically locates the TLE92466ED driver source files:

  1. CI/Build Environment: Looks for src/ and include/ in the project root
  2. Development Environment: Looks for ../../src/ and ../../include/ (driver root)

Source Files Included

  • src/TLE92466ED.cpp - Main driver implementation

Headers Included

  • inc/TLE92466ED.hpp - Driver class
  • inc/TLE92466ED_Registers.hpp - Register definitions
  • inc/TLE92466ED_CommInterface.hpp - Communication interface

Usage in Projects

In ESP-IDF Component Manager

This component can be used with the ESP-IDF Component Manager by adding it to your project’s dependencies.

In Local Projects

The component is automatically discovered by ESP-IDF when located in the components/ directory of your project.

Requirements

Add to your main component:

cmake idf_component_register( SRCS "main.cpp" INCLUDE_DIRS "." REQUIRES tle92466ed-espidf # Add this requirement ) text

Configuration

The component provides compile-time definitions based on the target:

  • TLE92466ED_TARGET_ESP32 - ESP32 classic target
  • TLE92466ED_TARGET_ESP32C6 - ESP32-C6 target
  • TLE92466ED_TARGET_ESP32S3 - ESP32-S3 target
  • TLE92466ED_TARGET_ESP32C3 - ESP32-C3 target
  • TLE92466ED_MCU_FAMILY_ESP32 - ESP32 family marker

Build Features

C++23 Standard

The component is configured to use C++23 standard:

cmake target_compile_features(${COMPONENT_LIB} PRIVATE cxx_std_23) text

Compiler Optimizations

  • Link Time Optimization (LTO): Enabled when configured
  • Function/Data Sections: For better code size optimization
  • No RTTI: -fno-rtti for smaller binary size
  • No Exceptions: -fno-exceptions for embedded systems

Compiler Flags

text -Wall -Wextra -Wpedantic -O2 -g -ffunction-sections -fdata-sections -fno-rtti -fno-exceptions text

Component Manager

Publishing to Component Registry

To publish this component to the ESP-IDF Component Registry:

  1. Update version in idf_component.yml
  2. Create git tag matching version
  3. Follow ESP-IDF Component Manager publishing guidelines

Local Installation

The component is automatically available when building the examples from the examples/esp32 directory.

Build Messages

During build, the component will display:

text TLE92466ED Driver - ESP32 Component Configuration Project Root: /path/to/project Source Root: /path/to/driver Found source: /path/to/TLE92466ED.cpp === TLE92466ED Driver Component Summary === Component configured successfully Included 1 source files Target MCU: ESP32-C6 C++ Standard: C++23 Driver Version: 2.0.0 Optimization: LTO enabled (if configured) ========================================== text

Troubleshooting

Source Files Not Found

Issue: “Source file not found” warnings

Solution: Verify the driver is in the correct location:

  • Development: ../../src/TLE92466ED.cpp relative to component
  • CI: ${PROJECT_ROOT}/src/TLE92466ED.cpp

C++23 Not Supported

Issue: Compiler doesn’t support C++23

Solution: Update to:

  • GCC 12.0 or later
  • Clang 16.0 or later
  • ESP-IDF v5.5 or later

Component Not Found

Issue: “Component ‘tle92466ed-espidf’ not found”

Solution: Ensure the component is in the components/ directory of your ESP-IDF project.
