Detailed description

No detailed description exists yet for this component

Examples

Basic example program which embeds a text file into the microcontrollers ROM memory and then prints the file out to a LCD display. FC6 Icon.png EmbedFileExample Text file to go with the example, must be placed into the same directory as the Flowcode file.

File:TextFile.txt


Here is an archive which packages the example and text file together for you.

ZIP Icon.png Embed File Example Files


The file is selected using the File component property.

Clicking the small arrow to the right of the property and selecting Browse allows you to select a file using a Windows file explorer.
