Previews

Greetings!

• 

Preview with a camera module attached to the Flipper Zero.

• 

Version 1.1.0 and above now supports new dithering options and bug fixes!

• 

Version 1.2.0 and above now supports taking pictures, configurable dithering, and LED flash!

Hardware Requirements

Requires an ESP32-CAM module (I've personally used these: Amazon Link 1 | Amazon Link 2).

Hardware Installation

Below is the pinout guide and diagram for the ESP32-CAM module to the Flipper Zero. From the ESP32-CAM module to the Flipper Zero:

VCC to 3V3
GND to GND (Be sure to use the right GND, see image below.)
U0R to TX
U0T to RX

On the ESP32-CAM module itself you'll also need to connect the IO0 pin to GND. This will place the module into flash mode for installing the firmware later on (see Firmware Installation). You can do this by connecting a jumper wire, a button, or a switch to do this.

Firmware Installation

Windows 10+ Script (the new, easy way)

1. Download/clone this repository to your computer. 2. Run the script found at the root of this directory: `firmware-flash.bat`. 3. Follow the on screen instructions to continue. That's it, let me know if you have any issues!

Arduino IDE (the old, hard way)

1. Download and install the Arduino IDE from [here][arduino-ide]. 2. Go to the [releases section][flipper-zero-camera-suite-releases] for this repo and download the `esp32_cam_uart_stream.zip` file. 3. Extract the contents of `esp32_cam_uart_stream.zip` to disk. Be sure to keep the `.ino` file nested in the folder with the same name. 4. Open `~\esp32_cam_uart_stream\esp32_cam_uart_stream.ino` with your Arduino IDE. 5. In the Arduino IDE, go to `File > Preferences`. 6. In the `Settings` tab, add the following URL to the `Additional Boards Manager URLs` field: ``` https://dl.espressif.com/dl/package_esp32_index.json ``` 7. In the Arduino IDE, go to `Tools > Board > Boards Manager`. 8. Search for `esp32` and install `esp32` by `Espressif Systems`. 9. Plug in your Flipper Zero via USB. Make sure qFlipper or something else isn't connected to it already after doing so. 10. On your Flipper Zero, open `GPIO > USB-UART Bridge`. 11. In the Arduino IDE, go to `Tools > Board > esp32 > AI Thinker ESP32-CAM`. 12. In the Arduino IDE, go to `Tools > Port` and select the port that your Flipper Zero is connected to. 13. Plug in the ESP32-CAM module to your Flipper Zero while connecting the `IO0` pin to `GND`. See [Hardware Installation](#hardware-installation) for more information. 14. Press the RST button on the back of the ESP32-CAM module to boot it into flash mode. 15. In the Arduino IDE, go to `Sketch > Upload` to upload the firmware to your ESP32-CAM module. You will see upload progress in % and receive a message on completion if successful. 16. Fin! Now you may use the [Software Installation](#software-installation) section to install the software on your Flipper Zero to take advantage of this hardwares firmware. Note the upload may fail a few times, this is normal, try again. If it still fails, try pressing the RST button on the back of the ESP32-CAM module again or checking your connections.

Software Installation

1. Connect your Flipper Zero via USB, or insert your MicroSD.
2. Navigate to the GitHub actions: https://github.com/CodyTolene/Flipper-Zero-Camera-Suite/actions
3. Open the most recent action and download the fap zip for either "dev" or "release" build versions of the Flipper Zero firmware.

4. Move "camera_suite.fap" into ~\apps\gpio\ on your Flipper Zero MicroSD:

   .                            # The Flipper Zero MicroSD root.
   ├── apps                     # The Flipper Zero Applications folder.
   |   ├── gpio                 # The Flipper Zero GPIO folder.
   |   |   ├── camera_suite.fap  # The Camera Suite application.
   

5. Reinsert your MicroSD into your Flipper Zero if you took it out.

6. Plug in your ESP32-CAM module to your Flipper Zero.

7. Press the "Power" button on your Flipper Zero to turn it on.

8. Open the application "[ESP32] Camera Suite":

   Applications > GPIO > [ESP32] Camera Suite
   

9. That's it! Follow the on screen instructions to continue.

Software Guide

Flipper Zero button mappings:

🔼 = Contrast Up

🔽 = Contrast Down

◀️ = Toggle invert.

▶️ = Toggle dithering on/off.

⚪ = Take a picture and save to the "DCIM" folder at the root of your SD card. Image will be saved as a bitmap file with a timestamp as the filename ("YYYYMMDD-HHMMSS.bmp"). If flash is on in the settings (enabled by default) the ESP32-CAM onboard LED will light up when the picture is taken.

↩️ = Go back.

Camera Suite settings:

Orientation = Rotate the camera image 90 degrees counter-clockwise starting at zero by default (0, 90, 180, 270). This is useful if you have your camera module mounted in a different orientation than the default.

Dithering Type Change between the Cycle Floyd–Steinberg, Jarvis-Judice-Ninke, and Stucki dithering types.

Flash Toggle the ESP32-CAM onboard LED on/off when taking a picture.

Haptic FX = Toggle haptic feedback on/off.

Sound FX = Toggle sound effects on/off.

LED FX = Toggle LED effects on/off.

For C development you will need the clang format tool for linting/formatting.

FOR /R C:\path-to-repo\Flipper-Zero-Camera-Suite\ %F IN (*.h *.ino *.c *.cpp) DO clang-format -i "%F"
