# InkyDash

A simple e-ink / epaper powered calendar with weather information and daily progres bar

## Usage

### Wiring

If you are using the offical PCB, then follow the silk screen wiring instructions. Otherwise, if you are using generic ESP8266, follow the following wiring instructions to connect your e-ink display SPI control board to your development board.

#### Wemos D1 mini

- BUSY -> D2

- RST -> D4

- DC -> D3

- CS -> D8

- CLK -> D5

- DIN -> D7

- GND -> GND

- 3.3V -> 3.3V

#### Generic ESP8266

- BUSY -> GPIO4

- RST -> GPIO2

- DC -> GPIO0

- CS -> GPIO15

- CLK -> GPIO14

- DIN -> GPIO13

- GND -> GND

- 3.3V -> 3.3V

### Customizations

#### Low Power Mode

If your InkyDash is running off battery, set LOW_POWER_MODE to true and add a resistor between the D0 / GPIO16 pin to the RST pin of the ESP8266. **This resistor is critical for the ESP8266 to wake up from deep sleep mode.** The resistor values depends on your development board, but usually 330R to 1k Ohm is commonly used by the community.

#### Weather Locations

You can change your weather location by editing these few lines in the weather.ino file.

```c
//Latitude & Longitude of your location
/* Hong Kong */
const String lat = "22.2783";
const String lon = "114.1747";

/* Timezone */
const String timezone = "Asia/Singapore";
```

The weather information is provided by `open-meteo.com`. They do not require API key for request count less than 500 per hour. You can modify the weather API if you already have a code snippet doing just that from your other projects. 

```c
// In updateCurrentWeatherInfo() function

//Update the current lines to your data sources
currentTemp = doc["current"]["temperature_2m"];
currentHumd = doc["current"]["relative_humidity_2m"];
currentRain = doc["current"]["rain"];
minTemp = doc["daily"]["temperature_2m_min"][0];
maxTemp = doc["daily"]["temperature_2m_max"][0];

```

### Firmware Downloading

Open "InkyDash" project with Arduino IDE and upload the firmware into the InkyDash control board.

### Supported Eink Models

Basically you can try this with any 7.5 inch eink display with 3 colors.
