RaspberryPi
The figure above shows Raspberry Pi 3 Model B+,
A short comparison to its’ predecessor the Raspberry Pi model B. The table below shows some of the Raspberry Pi 3 model B+ features.
Tasks (done by the Rpi3):
a. Mitigate the UI task(s); to be performed (e.g. Store Parcel Button pressed; this action is delegated).
b. Monitors the storage units; for availability, the Rpi3 will send a control ASCII character (‘M’) to the 8051, the monitor each storage unit (for more info, refer to the Tasks (done by the µC), point a).
c. It grants shoppers access; to store and retrieve their parcel (or small belongs); for more info, refer to the Tasks (done by the µC), point b.
d. Temporally archives the shopper’s SEI information; of the
e. It delegates the user interface communication between the above mentioned control behaviour, through the use of the system SEI database. Shopper and the system; this is handled by the, 4x4 keypad, and the 4x20 LCD display, shown below on figure 11 for reference.
The Raspberry Pi 3 will be used to perform the main sequential logic of the project. Control behaviour such as the ones mentioned at points A and B, can be achieved through the use of UART communication between the raspberry pi and the 8051 microcontroller; an instruction or acknowledgement comprises of, an ASCII byte code being sent back and forth these devices.
