# esp-idf-http-camera
Take a picture and Publish it via HTTP.
This project use [ESP32 Camera Driver](https://components.espressif.com/components/espressif/esp32-camera).
# Server Side

# ESP32 Side
# Hardware requirements
ESP32 development board with OV2640 camera.
If you use other camera, edit sdkconfig.default.
From the left:
- Aithinker ESP32-CAM
- Freenove ESP32-WROVER CAM
- UICPAL ESPS3 CAM
- Freenove ESP32S3-WROVER CAM (Clone)
## Software requirements
ESP-IDF V5.0 or later.
ESP-IDF V4.4 release branch reached EOL in July 2024.
## Installation
For AiThinker ESP32-CAM, you need to use a USB-TTL converter and connect GPIO0 to GND.
|ESP-32|USB-TTL|
|:-:|:-:|
|U0TXD|RXD|
|U0RXD|TXD|
|GPIO0|GND|
|5V|5V|
|GND|GND|
```
git clone https://github.com/nopnop2002/esp-idf-http-camera
cd esp-idf-http-camera
idf.py set-target {esp32/esp32s3}
idf.py menuconfig
idf.py flash monitor
```
## Start firmware
For AiThinker ESP32-CAM, Change GPIO0 to open and press the RESET button.
## Configuration
Set the following items using menuconfig.
### Wifi Setting
You can connect using the mDNS hostname instead of the IP address.
You can use static IP.
### HTTP Server Setting
### Attached File Name Setting
You can choose the file name on the HTTP server side from the following.
- Always the same file name
- File name based on date and time
When you choose date and time file name, you will need an NTP server.
The file name will be YYYYMMDD-hhmmss.jpg.
- Add FrameSize to Remote file Name
When this is enabled, FrameSize is added to remote file name like this.
`20210520-165740_800x600.jpg`
### Select Board
### Select Frame Size
Large frame sizes take longer to take a picture.
### Select Shutter
You can choose one of the following shutter methods
- Shutter is the Enter key on the keyboard
For operation check.
When using the USB port provided by the USB Serial/JTAG Controller Console, you need to enable the following line in sdkconfig.
```
CONFIG_ESP_CONSOLE_USB_SERIAL_JTAG=y
```
- Shutter is a GPIO toggle
- Initial Sate is PULLDOWN
The shutter is prepared when it is turned from OFF to ON, and a picture is taken when it is turned from ON to OFF.
- Initial Sate is PULLUP
The shutter is prepared when it is turned from ON to OFF, and a picture is taken when it is turned from OFF to ON.
I confirmed that the following GPIO can be used.
|GPIO|PullDown|PullUp|
|:-:|:-:|:-:|
|GPIO12|OK|NG|
|GPIO13|OK|OK|
|GPIO14|OK|OK|
|GPIO15|OK|OK|
|GPIO16|NG|NG|
- Shutter is TCP Socket
You can use tcp_send.py as shutter.
`python3 ./tcp_send.py`
- Shutter is UDP Socket
You can use udp_send.py as shutter.
Requires netifaces.
`python3 ./udp_send.py`
- Shutter is HTTP Request
You can use this command as shutter.
`curl "http://esp32-camera.local:8080/take/picture"`
### Flash Light
ESP32-CAM by AI-Thinker have flash light on GPIO4.
## PSRAM
When you use ESP32S3-WROVER CAM, you need to set the PSRAM type.
# View picture using Built-in WEB Server
ESP32 works as a web server.
You can view the pictures taken using the built-in WEB server.
Enter the ESP32's IP address and port number in the address bar of your browser.
You can connect using mDNS hostname instead of IP address.
