This program is an image viewer for ATOMS3 to display images on SPIFFS. There are two modes: "Manual mode," where images are displayed each time a button is pressed, and "Automatic mode," where images are displayed at regular intervals.

You can compile this program on the PlatformIO IDE environment.

The capacity of SPIFFS is 7 MiB allocated with the partition table no_ota_8MB.csv in this repository.

Place the 128 x 128 image files(PNG, JPEG, or BMP) to be displayed in the data directory.

You can transfer your image files in the data directory by selecting "Upload from the PlatformIO menu or invoking the command pio run --target uploadfs.

If you transfer the following configuration file data/image-viewer.json to SPIFFS with your image files, you can specify whether the automatic mode is on or off, the interval of switching image files in the automatic mode, and whether the random switch interval mode is on or off. If there is no configuration file, the automatic mode(AutoMode) is off(false), the interval(AutoModeInterval) is 3000 milliseconds, the random switch mode(AutoModeRandomized) is off(false) by default.

{
  "AutoMode": false,
  "AutoModeInterval": 3000,
  "AutoModeRandomized": false
}

When the random switch interval mode is turned on, the image will be switched at random intervals between 0 milliseconds and the number of milliseconds specified by AutoModeInterval(a new feature added in v0.0.4).

When ATOMS3 is started, the image files on SPIFFS are displayed in order. The orientation of the screen changes automatically according to the orientation of ATOMS3.

There are two ways to display images:

1. Manual mode
   Switch images every time you push the button on ATOMS3.
2. Automatic mode
   Switch images at regular intervals.

The default mode is the mode you specify in the configuration file. If you boot ATOMS3 while holding down the button, it will be forced to the automatic mode instead of your configuration.

After booting ATOMS3, the following will appear on the screen. If there is no configuration file, the information on Config: will not appear.

Image Viewer v0.0.2
Config:
 /image-viewer.json
 AutoMode: false
 Interval: 3000ms
 Randomized: false
Mode:
 Manual, Auto or Auto(Forced)
Image Files:
 ImageFile1
 ImageFile2

There are no image files on SPIFFS, the following will appear:

Image Viewer v0.0.2
Config:
 /image-viewer.json
 AutoMode: false
 Interval: 3000ms
 Randomized: false

The list of image files above is displayed for a time(the default is 3 seconds), and the image files on SPIFFS are displayed according to the display mode.
