        # ArduinoACePCalendar

![Picture](doc/picture.jpg)

This is a daily calendar using a color E-Paper display.

The screen is refreshed everyday with the image stored in the microSD card overlayed with today's date.

## Instruction

### Date & Time adjustment

First, you have to set date and time to RTC module.

A simple shell is available if the D3 pin is open, so you can control it through the serial interface with baud rate of 9600.

| Command |                                     |

|---------|-------------------------------------|

| NOW     | Show current date and time.         |

| DATE    | Set date by 8 digits (yyyymmdd).    |

| TIME    | Set time by 6 digits (HHMMSS).      |

| ALARM   | Set alarm time by 4 digits (HHMM).  |

| CLEAR   | Clear display with color (0-6).     |

| INDEX   | Set image index number (0-255).     |

| LOAD    | Load image data (0-255 or current). |

| EXAMINE | Examine function (0-3).             |

| HELP    | Show command help.                  |

| VERSION | Show version information.           |

| QUIT    | Quit shell.                         |

For example, enter command as follows to set January 16th 2022, 12:34:56.

```

ArduinoACePCalendar Shell

Version: X.XX (Xxx XX 20XX XX:XX:XX)

> date 20220116

OK

> time 123456

OK

> now

2022/1/16 12:35:03

> 

```

The screen is refreshed at 3:30 as default. If you'd like to change this 2:45, enter command as follows.

```

> alarm 0245

OK

> alarm

02:45

>

```

### Image conversion

Second, you have to convert the images to the particular format and save them to a microSD card.

As an image conversion tool, I produce a python script [`image2acp.py`](tools/image2acp.py).

To execute this script, you have to install not only [python 3.X](https://www.python.org/) but also [ImageMagick 7.X](https://imagemagick.org/script/index.php) because this script uses it.

You can obtain the file `sample1.acp` from `sample1.jpg` by entering following on console.

```

> python image2acp.py sample1.jpg

```

Then copy `*.acp` files into the root directory of a microSD card.

The order of images to display depends on the algorythm of file scanning in Arduino SD library. If all of `*.acp` files were displayed or 256th image was displayed, the first image will be desplayed again on the next day.

### Build environment

You can build the source code by Arduino IDE with following configuration.

* Board: "Arduino Pro or Pro Mini"

* Processor: "ATmega328P (3.3V 8MHz)"

Then, you can transfer binary data to Arduino Pro Mini by any writer.
