* Fails with ESP32 (standard) and ESP-IDF v5.2 With IDF 5.2 master it works with esp32-s3 but fails with esp32 standard, and has two problems: First is that when compiling it does not find the function: ets_delay_us'. implicit declaration of function 'ets_delay_us'; Second that it fails to initialize xlock. camera_xclk: ledc_timer_config failed, rc=103 The solution is to add #define ets_delay_us esp_rom_delay_us when the idf version is greater than 5 and initialize the variable timer_conf.deconfigure = false; * Build fails with ESP32 (Standard) and does not run with ESP-IDF v5.2 With IDF 5.2 master it works with esp32-s3 but fails with esp32 standard, and has two problems: First is that when compiling it does not find the function: ets_delay_us'. implicit declaration of function 'ets_delay_us'; Second that it fails to initialize xlock. camera_xclk: ledc_timer_config failed, rc=103 The solution is to add #define ets_delay_us esp_rom_delay_us when the idf version is greater than 5 and initialize the variable timer_conf.deconfigure = false; * Fails with ESP32 (Standard) and not run with ESP-IDF v5.2 With IDF 5.2 master it works with esp32-s3 but fails with esp32 standard, and has two problems: First is that when compiling it does not find the function: ets_delay_us'. implicit declaration of function 'ets_delay_us'; Second that it fails to initialize xlock. camera_xclk: ledc_timer_config failed, rc=103 The solution is to add #define ets_delay_us esp_rom_delay_us when the idf version is greater than 5 and initialize the variable timer_conf.deconfigure = false; --------- Co-authored-by: Me No Dev <me-no-dev@users.noreply.github.com>
