Compiling for ESP32-cam, using PlatformIO in 2023

[aranFish]

Dear Pierre,

Thank you for sharing your code to link an OV7725 image sensor with an ESP32-CAM. I am attempting to do the same task using your code, but am struggling to get the code to compile correctly using PlatformIO.

If I compile your code 'as-is', I get three main types of error:

src/ov2640.c:578:14: error: 'TAG' undeclared (first use in this function); did you mean 'YAVG'?. This error occurs in nearly all the .c files in the src folder, that contain these lines of code:

src/main.cpp:92:33: error: 'union arduino_event_info_t' has no member named 'disconnected'; did you mean 'eth_connected'?. This error occurs in main.cpp

src/main.cpp:111:56: error: cannot convert 'esp_interface_t' to 'wifi_interface_t, again in main.cpp.

I am using an ESP32-CAM AI-Thinker board. Thank you for your help, and already sharing your code - it's giving me a great head start.

Hi !
It's been a while since I opened this project. I remember I also had trouble to compile it.
I'll try to find a bit of time next weekend to reload this project with the last PlatformIO version, and let you know here.
Thanks a lot for your nice words ! I remember tried a lot of tweaks to have the OV7725 working, motivated by the better sensitivity of this sensor.
Cheers,
Pierre

Thanks Pierre, I really appreciate it :) Perhaps I'm biting off more than I can chew - - - onboarding myself onto a new microcontroller (ESP32), as well as a new development environment (PlatformIO) after years of using Arduino!
