Show Picture Sample

NanoComputer Application: ShowPicture.ihx

Note: First download Pirate.pic and save to your C:\ drive, then upload the file to the NanoComputer using the following command:

NC_CMD --upload Pirate.pic

Note: The source code below uses arguments passed into the NanoComputer Application. To have the ShowPicture application show the Pirate.pic picture the application should be invoked as follow:

NC_CMD --run ShowPicture Pirate.pic
