 == Conclusion ==
-Altogether, we really enjoyed being in this class and do this project. We faced many difficulties throughout the semester including searching for the project, planning and executing it. But each time we faced a problem, we got to learn many new things. The difficulties led to the deeper knowledge. All of us were stucked at our individual tasks at some point or the other, but we helped each other and finally made our project up and running. Not to mention, Preet was always easily approachable. Our project is running from top to bottom, sending an alphabet or a number from a cell phone, passing it to other board on the CAN network and printing on the LED cubes. The character is sent to only that node for which it was meant for. There are also patterns of the display in the cubes which really looks beautiful. We have uploaded everything regarding this project on this page. We honestly appreciate your interest in reading this page. Thank you!

In case if an a user uses wrong format to send a message from android phone, a message will be sent from LPC board over bluetooth to mobile device about the error.

 due to the perception of vision, we will see some garbage output. Hence, just when we are done shifting a total of 32 output bit (4 bytes), we will latch the data to the output pins by pulling the RCLK pin high using software(GPIO) and then again lowering it later.

 *'''Shift Register pin connections with the board:'''
- *We are using 8 bits from the shift register as parallel output data.
+We are using 8 bits from the shift register as parallel output data,VCC and ground connections are made with the board.The SRCLK is bit shifting clock which comes from the SSP1 clock.The SRCLR is an active low pin and is being driven high along with the Output Enable permanently to never reset the storage register in the shift register and to enable the shift register respectively. RCLK is the latching clock and It is connected with a GPIO pin on the board. When this pin is low the output of the shift register is in the floating state, no matter where the bit is reached in the storage register. When this pin becomes high, the storage register data latches with the output pins. The SER is the serial input data which comes from the board as the MOSI input. The OUT pin is the output serial data. This is the same incoming data into the register. But, it has been shifted 8 times first and then only given out and it is used for cascading.

−	In this screen, there are two options provided that are we can send and receive serial data simultaneously. In the upper part of the screen the buttons are provided to disconnect with the device and clear the input received from the other connected device. The serial data received is displayed right under the above two button. In the lower part the screen, we have the option of sending serial data to the connected device. We can directly enter data by clicking Enter Command screen option by using onscreen keyboard. After entering the desired data we can send it by clicking the Send button. ~~But~~, in ~~this project we are only using the serial data transmitting facility of~~ the ~~application~~.	+	In this screen, there are two options provided that are we can send and receive serial data simultaneously.

If user Input anything invalid other then suggested transmission protocol standard, then an error message will be returned back to Android application in received message section and no change in output will occur at the output LED cubes.
