You request the use of a +header file in your project source file (C, C++, etc) located in `src` folder +by including it, with the C preprocessing directive `#include'. + +```src/main.c + +#include "header.h" + +int main (void) +{ + ... +} +``` + +Including a header file produces the same results as copying the header file +into each source file that needs it. Such copying would be time-consuming +and error-prone. With a header file, the related declarations appear +in only one place. If they need to be changed, they can be changed in one +place, and programs that include the header file will automatically use the +new version when next recompiled. The header file eliminates the labor of +finding and changing all the copies as well as the risk that a failure to +find one copy will result in inconsistencies within a program. + +In C, the usual convention is to give header files names that end with `.h'. +It is most portable to use only letters, digits, dashes, and underscores in +header file names, and at most one dot. + +Read more about using header files in official GCC documentation: + +* Include Syntax +* Include Operation +* Once-Only Headers +* Computed Includes + +https://gcc.gnu.org/onlinedocs/cpp/Header-Files.html diff --git a/lib/README b/lib/README new file mode 100644 index 0000000..2593a33 --- /dev/null +++ b/lib/README @@ -0,0 +1,46 @@ + +This directory is intended for project specific (private) libraries. +PlatformIO will compile them to static libraries and link into executable file. + +The source code of each library should be placed in an own separate directory +("lib/your_library_name/[here are source files]"). + +For example, see a structure of the following two libraries `Foo` and `Bar`: + +|--lib +| | +| |--Bar +| | |--docs +| | |--examples +| | |--src +| | |- Bar.c +| | |- Bar.h +| | |- library.json (optional, custom build options, etc) https://docs.platformio.org/page/librarymanager/config.html +| | +| |--Foo +| | |- Foo.c +| | |- Foo.h +| | +| |- README --> THIS FILE +| +|- platformio.ini +|--src + |- main.c + +and a contents of `src/main.c`: +``` +#include +#include + +int main (void) +{ + ... +} + +``` + +PlatformIO Library Dependency Finder will find automatically dependent +libraries scanning project source files. + +More information about PlatformIO Library Dependency Finder +- https://docs.platformio.org/page/librarymanager/ldf.html diff --git a/platformio.ini b/platformio.ini new file mode 100644 index 0000000..60e2867 --- /dev/null +++ b/platformio.ini @@ -0,0 +1,17 @@ +; PlatformIO Project Configuration File +; +; Build options: build flags, source filter +; Upload options: custom upload port, speed and extra flags +; Library options: dependencies, extra library storages +; Advanced options: extra scripting +; +; Please visit documentation for the other options and examples +; https://docs.platformio.org/page/projectconf.html + +[env:esp32cam] +platform = espressif32 +board = esp32cam +framework = arduino +monitor_speed = 115200 + +lib_deps = https://github.com/eloquentarduino/EloquentEsp32cam.git \ No newline at end of file diff --git a/src/main.cpp b/src/main.cpp new file mode 100644 index 0000000..106a06c --- /dev/null +++ b/src/main.cpp @@ -0,0 +1,94 @@ +#include +/** + * Run motion detection at low resolution. + * On motion, capture frame at higher resolution + * for SD storage. + * + * BE SURE TO SET "TOOLS > CORE DEBUG LEVEL = INFO" + * to turn on debug messages + */ +#include +#include + +using eloq::camera; +using eloq::motion::detection; + + +/** + * + */ +void setup() { + delay(3000); + Serial.begin(115200); + Serial.println("___MOTION DETECTION + SWITCH RESOLUTION___"); + + // camera settings + // replace with your own model! + camera.pinout.aithinker(); + camera.brownout.disable(); + camera.resolution.vga(); + camera.quality.high(); + + // see example of motion detection for config values + detection.skip(5); + detection.stride(1); + detection.threshold(5); + detection.ratio(0.2); + detection.rate.atMostOnceEvery(5).seconds(); + + // init camera + while (!camera.begin().isOk()) + Serial.println(camera.exception.toString()); + + Serial.println("Camera OK"); + Serial.println("Awaiting for motion..."); +} + +/** + * + */ +void loop() { + // capture picture + if (!camera.capture().isOk()) { + Serial.println(camera.exception.toString()); + return; + } + + // run motion detection + if (!detection.run().isOk()) { + Serial.println(detection.exception.toString()); + return; + } + + // on motion, perform action + if (detection.triggered()) { + Serial.printf( + "Motion detected on frame of size %dx%d (%d bytes)\n", + camera.resolution.getWidth(), + camera.resolution.getHeight(), + camera.getSizeInBytes() + ); + + Serial.println("Taking photo of motion at higher resolution"); + + camera.resolution.at(FRAMESIZE_UXGA, []() { + Serial.printf( + "Switched to higher resolution: %dx%d.
