2.3 Host software architecture
The host software is programmed in Java. The host software is capable of displaying
streams of images on its display panel, recording, playing back or deleting any recordings
selected by the user. It receives incoming data from the PC-side embedded system via
UART and analyzes it. When a full frame of image is received, it updates the display
panel with the latest image and if the recording function is enabled, it stores a copy of the
image in local memory. The application organizes a main thread which executes from
program start up and two minor threads that handle auto-reconnect of serial connection
and recording playback respectively.
