Hardware Aspects of Moving Message Display Project

Hardware Aspects of Moving Message Display Project:-
The moving message display is fabricated using these major components:-
1. Micro controller AT89s51
2. LCD
3. RS-232
4. Computer
the moving message will be display on the LCD which will be controlled through microcontroller and the message will be sent by computer using RS232. The circuit diagram of the moving message display is shown in this post and how the whole process is completed is discussed here.
The Microcontroller in this software is programmed such that it controls the LCD through an interface. An eight-bit interface between in the LCD and Microcontroller is programmed to transfer the data to be written on the LCD display screen. A further three out pins of the Microcontroller are used to generate control signals for the LCD. The three control signals are generated in the same pattern as discussed in the timing diagram in the previous chapters.
The project, when looked in totality, can be seen as composing of three components, namely LCD, Microcontroller and serial port. The three components have been discussed independently until now and to give a complete picture, it is necessary to link these components. The linking is not only logical but is also translated into hardware connections.
4.1 Serial Port to Microcontroller
The serial port is connected to the Microcontroller to provide the end user with the functionality of passing a desired string to LCD in run time. An interface between the serial port and the Microcontroller is required for the data transfer.
A variable baud rate is generated by the Microcontroller to synchronize the data transfer between the two ends. The connectivity can be analyzed and understood by the hardware diagram at the end of the chapter.
4.2 Microcontroller to LCD
The Microcontroller connects with the LCD with an 8bit interface to for data transfer. Three further pins are required to generate enable, read/write and instruction / data signals for the LCD. These three form a small instruction set that allows different tasks and the functionality provided by the HD44 LCD.
4.2.1 Enable Signal Connection
The enable signal is used as a signal to the LCD by the Microcontroller about the availability of data. A high-to-low edge triggers the LCD into reading its data lines. The data meant for the LCD must be present and latched on the data lines before the enable signal switches from high to logic low. It needs to be understood that data lines for sending instructions and display data are the same, the instruction bits help differentiate among the two for the LCD.
4.2.2 Read/Write Signal Connection
The read/write signal specifies to the LCD whether the Microcontroller is intends to read data from its DDRAM/CGRAM or intends to write data to its DDRAM/CGRAM. In the former case, the data lines contain the data meant for the destination on the LCD memory and in the latter case; the data lines will have the data written onto from the appropriate DDRAM/CGRAM.
4.2.3 Instruction/Data Signal Connection
The instruction/data line specifies whether the data bus contains an instruction or data meant for the LCD. This signal, along with the instruction bits, help LCD in deciding which control signals to generate to fulfill the request.

4.2.4 Busy Flag
After sending of every request, whether instruction or data, to the LCD; the Microcontroller must check for the busy flag of the LCD to return to low logic again. A high logic for the busy flag signals that an internal operation is being carried out and during this time, no external instruction or data is entertained. Only when the busy flag is at a logic low, the Microcontroller should send the next instruction or data. The busy flag is checked by configuring the LCD into read mode (R/W signal is set to logic high) and then reading the data lines. The MSB of the byte read contains the value of the busy flag. To understand the above concepts, the timing diagram mentioned in Chapter 2 for busy flag testing and data transfer may be used.

    I am unable to understand , why the code is compiled, i think there would be some errors during copy and paste.
    try to fix the error, if you still donot fix the errors in the code of moving message display then put the error here, and see if some one do it for you.

  6. @ Anonymous :-
    Can you not find the circuit daigram of moving message display on this www.microcontroller51.blogspot.com.
    The circuit diagram , program or code and report of the project in which moving message display is developed on LCD is already uploaded.
    Plz first scan all the post and then ask, if you feel difficulty in undersatnding any part of program or confused about the components used in hardware of moving message display with microcontroller 8051 on LCD. YOu can ask question.

    Regarding Moving Message Display using LED matrix and Microcontroller.
    First of all, this project is not related to LED display, in this project where you have written the comment is moving message display but using LCD (small, two line and 16 characters). IF you need help in other project then please go to rlevent links.
    For LED moving message display using PIC Microcontroller, below are two download links of projects:
    1. LED moving message diaply using PIC16f628 CD4017 and 74LS595 at http://picinf.blogspot.com/2011/09/led-moving-message-diaply-using.html
    2. Moving Message Display MMD with LED matrix using PIC Microcontroller PIC16f628 at http://picinf.blogspot.com/2011/09/led-moving-message-diaply-using.html
    for further any question regarding microcontrollers projects please ask in comments section of relvent microcontroller project.
