esp-idf 5.0: periph_module_enable() not found (AIV-467)

[pius-braun]

Thank you all for this great repository.

I just installed ESP-IDF 5.0 and then compiled the latest version of "examples/human_face_detection/terminal", prompting a compiler error "implicit declaration of function". With esp-idf 4.3, it compiled successfully.

I'm on WIndows 10, my target is the AI-Thinker esp32-cam. This is a snippet of the error messages.

...
C:/ESP32/esp-who/components/esp32-camera/target/esp32/ll_cam.c:281:5: error: implicit declaration of function 'periph_module_enable'; did you mean 'esp_intr_enable'? [-Werror=implicit-function-declaration]
     periph_module_enable(PERIPH_I2S0_MODULE);
     ^~~~~~~~~~~~~~~~~~~~

     periph_module_enable(PERIPH_I2S0_MODULE);

         periph_module_enable(PERIPH_I2S0_MODULE);
         ^~~~~~~~~~~~~~~~~~~~

My workaround: I added to C:\ESP32\esp-who\components\esp32-camera\target\esp32\ll_cam.c

#include "esp_private/periph_ctrl.h"
#include "soc/periph_defs.h"

and to C:\ESP32\esp-who\components\bus\i2s_lcd_esp32_driver.c

#include "esp_private/periph_ctrl.h"

It does look wrong, to include from an "esp_private" directory. Any other fix?

@pius-braun It seems the ESP-IDF change some API names in the master branch, the esp-idf 5.0. Would you mind switching esp-idf to v4.4-dev?

[pius-braun]

It worked with v4.4.

C:\ESP32\esp-who\examples\human_face_detection\terminal>idf.py --version
ESP-IDF v4.4-beta1

Thanks.
