WIO User Bitmaps

File System

The SPIFFS, SPI Flash File System, is required to be able to Upload user defined images to the WIO sketch.
See: WIO Firmware


The AMP (ASCII-MAP) Format

To make it easy to define a small bitmap/icon, an ASCII-MAP text file format is used.
The file name format is defined as follows:

<number>.amp

The number is in range between 0 and 999.
The maximum size is 128x64 pixel.
Tip: It is recommended to use a simple text editor with a monospace font like Courier.

Example

Lines starting with a '#' are regarded as comment.
All other lines contains X'es and white space. Any character can be used as white space, excluding the 'x' and 'X'.
In the following example blanks are used as white space.
The bitmap/icon width and height are calculated automatically.
An 'X' represents a display pixel which should be turned on.

# DB, Deutsch Bahn, Logo
 XXXXXXXXXXX 
X           X
X XXX  XXX  X
X X  X X  X X
X X  X XXX  X
X X  X X  X X
X XXX  XXX  X
X           X
 XXXXXXXXXXX

The {b#} display command is used to make it visible.
See: Display commands

The text content in Rocrail for this example:

{E}
{L0X0b55X18} Deutsche Bahn
{L2X0b56X18} Nederlandse Spoorwegen
{L4X0b999}
{P}

(55.amp is the DB, 56.amp the NS, and 999.amp the Rocrail logo.)
