esp-idf-remote-camera

esp-idf-remote-camera-2

Software requirements

esp-idf ver4.1 or later.

Install

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-remote-camera
cd esp-idf-remote-camera
git clone https://github.com/espressif/esp32-camera components
make menuconfig
make flash monitor

Start firmware

Change GPIO0 to open and press the RESET button.

Configuration

Set the following items using menuconfig.

config-main

config

File system

ESP32 supports the following file systems.
1.SPIFFS file system on FLASH
2.FAT file system on FLASH
3.FAT file system on SPI peripheral SDCARD
4.FAT file system on SDMMC peripheral SDCARD

You can select any one using menuconfig.

config-filesystem

  • 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

config-wifi

FTP server

config-ftpserver

You can choose the file name on the FTP server side from the following.
1.Always the same file name
2.File name based on date and time

config-filename

When you choose date and time file name, you will need an NTP server.

config-ftpserver-2

Fixed file name

file-name-fixed

File name based on date and time

file_name_datetime

Camera Pin

config-camerapin

Picture Size

config-picturesize

Shutter method

You can choose one of the following shutter methods

config-shutter-2

  • Shutter is the Enter key on the keyboard
    For operation check

config-shutter-1

  • 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

config-shutter-3

  • Shutter is TCP Socket

You can connect with mDNS hostname.
You can use tcp_send.py.

python ./tcp_send.py

config-shutter-4

  • Shutter is UDP Socket
    You can use udp_send.py.
python ./udp_send.py

config-shutter-5

Flash Light

ESP32-CAM by AI-Thinker have flash light on GPIO4.
