A size-adaptable RGB-LED array for displaying images and animations.
Segment managers are the base layer of the display structure. They directly interface with the RGB-LEDs via a series of shift registers. They have constant dimensions, but they can be placed parallel to eachother to expand the overall display dimensions. They are controlled via the TWI protocol (each having a unique address) by the imaging manager.
The Imaging Manager is the volatile image data layer of the display structure. It directly interfaces with the Segment Managers via TWI to produce specific patterns. It is controlled via USART by the Display Controller, and is indirectly interfaced with other high-speed, high-capacity storage devices. It unloads and controls the rendering of all media from the storage devices by controlling the Segment Managers individually.
The Display Controller is the application layer of the display structure. It is indirectly interfaced with the high-speed, high-capacity storage devices and directly interfaced with the Imaging Manager. The Display Controller is responsible for loading all media to the storage devices, and it controls the way that data is interpreted by the imaging manager via the USART interface with the Imaging Manager. It also directly controls the Communications Manager via the SPI protocol in order to get information from the master computer.
The Communications Manager is the module responsible for direct communication with the master computer. It loads command data to the display controller and relays status data back to the master computer.
