# _Sample project_
(See the README.md file in the upper level 'examples' directory for more information about examples.)
This is the simplest buildable example. The example is used by command `idf.py create-project`
that copies the project to user specified path and set it's name. For more information follow the [docs page](https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/build-system.html#start-a-new-project)
## How to use example
We encourage the users to use the example as a template for the new projects.
A recommended way is to follow the instructions on a [docs page](https://docs.espressif.com/projects/esp-idf/en/latest/api-guides/build-system.html#start-a-new-project).
## Example folder contents
The project **sample_project** contains one source file in C language [main.c](main/main.c). The file is located in folder [main](main).
ESP-IDF projects are built using CMake. The project build configuration is contained in `CMakeLists.txt`
files that provide set of directives and instructions describing the project's source files and targets
(executable, library, or both).
Below is short explanation of remaining files in the project folder.
```
├── CMakeLists.txt
├── main
│   ├── CMakeLists.txt
│   └── main.c
└── README.md This is the file you are currently reading
```
Additionally, the sample project contains Makefile and component.mk files, used for the legacy Make based build system.
They are not used or needed when building with CMake and idf.py.

# ESP32 Camera Driver
[![Build examples](https://github.com/espressif/esp32-camera/actions/workflows/build.yml/badge.svg)](https://github.com/espressif/esp32-camera/actions/workflows/build.yml) [![Component Registry](https://components.espressif.com/components/espressif/esp32-camera/badge.svg)](https://components.espressif.com/components/espressif/esp32-camera)
## General Information
This repository hosts ESP32 series Soc compatible driver for image sensors. Additionally it provides a few tools, which allow converting the captured frame data to the more common BMP and JPEG formats.
### Supported Soc
- ESP32
- ESP32-S2
- ESP32-S3

## Important to Remember
- Except when using CIF or lower resolution with JPEG, the driver requires PSRAM to be installed and activated.
- Using YUV or RGB puts a lot of strain on the chip because writing to PSRAM is not particularly fast. The result is that image data might be missing. This is particularly true if WiFi is enabled. If you need RGB data, it is recommended that JPEG is captured and then turned into RGB using `fmt2rgb888` or `fmt2bmp`/`frame2bmp`.
- When 1 frame buffer is used, the driver will wait for the current frame to finish (VSYNC) and start I2S DMA. After the frame is acquired, I2S will be stopped and the frame buffer returned to the application. This approach gives more control over the system, but results in longer time to get the frame.
- When 2 or more frame bufers are used, I2S is running in continuous mode and each frame is pushed to a queue that the application can access. This approach puts more strain on the CPU/Memory, but allows for double the frame rate. Please use only with JPEG.
## Installation Instructions
### Using with ESP-IDF
- Add a dependency on `espressif/esp32-camera` component:
```bash
idf.py add-dependency "espressif/esp32-camera"
```
(or add it manually in idf_component.yml of your project)
- Enable PSRAM in `menuconfig` (also set Flash and PSRAM frequiencies to 80MHz)
- Include `esp_camera.h` in your code
These instructions also work for PlatformIO, if you are using `framework=espidf`.
### Using with Arduino
#### Arduino IDE
If you are using the arduino-esp32 core in Arduino IDE, no installation is needed! You can use esp32-camera right away.
#### PlatformIO
The easy way -- on the `env` section of `platformio.ini`, add the following:
```ini
[env]
lib_deps =
esp32-camera
```
Now the `esp_camera.h` is available to be included:
```c
#include "esp_camera.h"
```
Enable PSRAM on `menuconfig` or type it direclty on `sdkconfig`. Check the [official doc](https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-reference/kconfig.html#config-esp32-spiram-support) for more info.
```
CONFIG_ESP32_SPIRAM_SUPPORT=y
```
## Examples
This component comes with a basic example illustrating how to get frames from the camera. You can try out the example using the following command:
```
idf.py create-project-from-example "espressif/esp32-camera:camera_example"
```
This command will download the example into `camera_example` directory. It comes already pre-configured with the correct settings in menuconfig.

// jpge.cpp - C++ class for JPEG compression.
// Public domain, Rich Geldreich <richgel99@gmail.com>
// v1.01, Dec. 18, 2010 - Initial release
// v1.02, Apr. 6, 2011 - Removed 2x2 ordered dither in H2V1 chroma subsampling method load_block_16_8_8(). (The rounding factor was 2, when it should have been 1. Either way, it wasn't helping.)
// v1.03, Apr. 16, 2011 - Added support for optimized Huffman code tables, optimized dynamic memory allocation down to only 1 alloc.
// Also from Alex Evans: Added RGBA support, linear memory allocator (no longer needed in v1.03).
// v1.04, May. 19, 2012: Forgot to set m_pFile ptr to NULL in cfile_stream::close(). Thanks to Owen Kaluza for reporting this bug.
// Code tweaks to fix VS2008 static code analysis warnings (all looked harmless).
// Code review revealed method load_block_16_8_8() (used for the non-default H2V1 sampling mode to downsample chroma) somehow didn't get the rounding factor fix from v1.02.
