## General Information
This repository hosts ESP32 compatible driver for OV2640 and OV3660 image sensors. Additionally it provides a few tools, which allow converting the captured frame data to the more common BMP and JPEG formats.

## Installation Instructions
### Using esp-idf
- Clone or download and extract the repository to the components folder of your ESP-IDF project
- Enable PSRAM in `menuconfig`
- Include `esp_camera.h` in your code
### Using PlatformIO
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
```
**Make sure to append** [this `Kconfig`](./Kconfig) content into the `Kconfig` of your project. Then, choose the configurations according to your setup.
### Kconfig options
| config | description | default |
| --------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------ | ------------------------------ |
| CONFIG_OV2640_SUPPORT | Support for OV2640 camera | enabled |
| CONFIG_OV7725_SUPPORT | Support for OV7725 camera | disabled |
| CONFIG_OV3660_SUPPORT | Support for OV3660 camera | enabled |
| CONFIG_OV5640_SUPPORT | Support for OV5640 camera | enabled |
| CONFIG_SCCB_HARDWARE_I2C | Enable this option if you want to use hardware I2C to control the camera. Disable this option to use software I2C. | enabled |
| CONFIG_SCCB_HARDWARE_I2C_PORT | I2C peripheral to use for SCCB. Can be I2C0 and I2C1. | CONFIG_SCCB_HARDWARE_I2C_PORT1 |
| CONFIG_CAMERA_TASK_PINNED_TO_CORE | Pin the camera handle task to a certain core(0/1). It can also be done automatically choosing NO_AFFINITY. Can be CAMERA_CORE0, CAMERA_CORE1 or NO_AFFINITY. | CONFIG_CAMERA_CORE0 |
