# Custom Characters

This Node allows you to send custom characters to an LCD display in Node-RED. You can easily create custom characters using the [LCD Character Creator](https://maxpromer.github.io/LCD-Character-Creator/) tool and send them to your display.

1. Create a Custom Character:

   * Go to the [LCD Character Creator](https://maxpromer.github.io/LCD-Character-Creator/).

   * Design your custom character.

   * Set the "Data Type" option to "Hex."

   * Copy the generated hex values for the custom character.

2. Format the Custom Character Payload:

   After generating the hex values, you need to format the data into a payload before sending it to the LCD display. To send multiple custom characters, use an array of objects for `msg.cusChars`.

   ```javascript

   msg.cusChars = [

      {

         "char": [0x1F, 0x1F, 0x1F, 0x1F, 0x1F, 0x1F, 0x1F, 0x1F],

         "row": 0,

         "col": 0

      },

      {

         "char": [0x00, 0x01, 0x02, 0x04, 0x08, 0x10, 0x00, 0x00],

         "row": 0,

         "col": 1

      }

   ];

   return msg;

   ```

   * The `msg.cusChars` property should contain an array of character objects.

   * Each object must contain the `char` data (the hex values), and optionally the `row` and `col` to specify the character's position.

3. Send the Payload:

   Once the payload is formatted, send it to your LCD display using the appropriate function or node to update the display with your custom characters.
