esp-idf-ftp-camera

Take a picture and Publish it via FTP.
This project use ESP32 Camera Driver.
This project use ESP32-FTP-Client.

Hardware requirements

ESP32-CAM Development board.
Support for OV2640 camera.
If you use other camera, edit sdkconfig.default.

Software requirements

esp-idf v4.3 or later.

Installation

Use a USB-TTL converter.

ESP-32	USB-TTL
U0TXD	RXD
U0RXD	TXD
GPIO0	GND
5V	5V
GND	GND

git clone https://github.com/nopnop2002/esp-idf-ftp-camera
cd esp-idf-ftp-camera
git clone https://github.com/espressif/esp32-camera components/esp32-camera
idf.py set-target esp32
idf.py menuconfig
idf.py flash monitor

Start firmware

Change GPIO0 to open and press the RESET button.

Configuration

Set the following items using menuconfig.

File system Selection

ESP32 supports the following file systems.

SPIFFS file system on FLASH
FAT file system on FLASH
FAT file system on SPI peripheral SDCARD
FAT file system on SDMMC peripheral SDCARD

You can select any one using menuconfig.

Using FAT file system on SPI peripheral SDCARD

Must be formatted with FAT32 before use

ESP32 pin	SPI pin	Notes
GPIO14(MTMS)	SCK
GPIO15(MTDO)	MOSI	10k pull up if can't mount
GPIO2	MISO
GPIO13(MTCK)	CS
3.3V	VCC	Can't use 5V supply
GND	GND

Using FAT file system on SDMMC peripheral SDCARD

Must be formatted with FAT32 before use

ESP32 pin	SD card pin	Notes
GPIO14(MTMS)	CLK	10k pullup
GPIO15(MTDO)	CMD	10k pullup
GPIO2	D0	10k pullup
GPIO4	D1	not used in 1-line SD mode; 10k pullup in 4-line SD mode
GPIO12(MTDI)	D2	not used in 1-line SD mode; 10k pullup in 4-line SD mode
GPIO13 (MTCK)	D3	not used in 1-line SD mode, but card's D3 pin must have a 10k pullup
N/C	CD	optional, not used in the example
N/C	WP	optional, not used in the example

Wifi Setting

You can use the mDNS hostname instead of the IP address.

esp-idf V4.3 or earlier
You will need to manually change the mDNS strict mode according to this instruction.
esp-idf V4.4 or later
If you set CONFIG_MDNS_STRICT_MODE = y in sdkconfig.default, the firmware will be built with MDNS_STRICT_MODE = 1.

You can use static IP.

FTP server Setting

You can specify mDNS hostname for the FTP server.

Remote File Name Setting

You can choose the file name on the FTP 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 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

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.
