It supports officially both parallel and serial communication to the Arduino. Other microcontrollers also able to operate the LCD with the use of three control pins and eight digital pins, which makes parallel communication. Led uses the back light-blocking method to display the data. Furthermore, it has internal controllers and registers which makes it easy to understand and use without even use of libraries. There is a total of 20 pins, which gives serial and parallel communication features.
We provide functions of all the pins in the preceding sections:. Each pixel is made up of 5 small layers. The outer most layer is known as the protection layers. The other three-layer make each pixel on the LCD Screen. The inner layer two layers make the sandwich of liquid crystals. The layers have polarized path opposite each other.
The polarized layers also act as anode and cathode. When the power applies to the polarized layers then the crystal changes their direction and lets the backlight go through itself.
Each pixel will control by the driver ST The driver has multiple pins, the main input pins are 18 which are already been discussed in the Pin Configuration. The rest of the pins connects with the pixels in the form of row and column.
The output pins are X64 in numbers and they control every pixel. The driver has internal registers, which act as data and instructions registers. Therefore, the input pins will help to control the resister and these pins will make the data display on the GLCD. The data registers get fill and then show the data. To replace the data on the screen the data register needs to replace with new data. So always clear the LCD the previous data before replacing the new data.
The command registers are also needed to replace the data but only the opposite in functions with each other. We can interface it with microcontrollers with two methods. The first method is using parallel pins and the second pins are serial communication pins.
This example of the LCD is mostly available in Arduino. Arduino uses the following circuit to operate serially. After initializing the library, the pins need to describe. For Serial only the following pin needs to describe in the Arduino. Here we will use the serial method because the parallel method is efficient with the library and also follow the same protocol.A graphical LCD is an electronic display unit which can display any type of elements provided by the user.
Unlike a character LCD which can only display alphanumeric characters, a graphical LCD can display images, fonts and other structures. In comparison with character LCD, it can display anything on the screen provided by the user. Character LCD only displays the alphanumerical characters.
The user can create images, fonts and other structures and display on them. KS is a dot matrix display controller from Samsung with 64 channel output. To generate timing signals for these two controllers, there is a common driver KS It has 8 data lines, 6 control lines and 6 power and display related pins.

Pin descriptions are given below. We use these pins to transfer the data to the display RAM. Connect these pins to 5V and ground respectively.
The pin 18 is the output of a negative voltage generator. By using a potentiometer, we can generate the required operating voltage by feeding the negative voltage to the Vo pin.
We can vary Vo to change the contrast of the display. The 19 and 20 pins are Anode and cathode of backlit LED, limit the current through it by putting a resistor in the line.
We can use a pot if you need to vary this too.
RST is the reset pin, it is used to reset the entire display content by clearing whole of the display RAM. One of the important consideration while clocking is, always give at least 1 microsecond delay after every instruction or data transfer. This parameter will be defined as Ecycle in the datasheet of the module. For JHD, the Ecycle value is 1us.
KS is a 64 channel common driver which generates timing signals to control the other two KS segment drivers. There is also a negative voltage generator which outputs the negative voltage through Vee pin. In some display modules, this section may not be present. So we will need to generate the negative voltage from outside. In some GLCD displays, the segment and common drivers used will be made by different manufacturer, but they will be compatible with KS controllers.
There are 8 pages in each half which is controlled by each KS controller. One page one row contains 64 columns of 8 rows.Build a DIY screen out of recycled parts for cheap
Whenever we transfer the data, we first selects the half by CS bits, then page address X and then the Y address. The byte will be transferred as a 1 bit wide strip and will be stored in display RAM location.
We can summarise this process as follows. We will be leaving first two columns, 8th column and last row of the page for spacing.Note: For users with a Printed Solid Enclosure3D print this replacement bracket as shown in image, and have a 2. Want to learn more about this 3D model?

They may need to be moved around slightly in order to pass the harness through. Notice that P1 is on bottomand P2 is just above P1. Note: To keep track of separate harness connections, it is suggested to connect the harness with the white label to P2.
On the LulzBot Mini v1. P1 is on the left, P2 is on the right. It's important to connect the harness with the white label to P2, to match the connections on the RAMBo.
Note: For users with the LulzBot Mini Enclosure by Printed Solidremove the front set of enclosure panels and the center set of enclosure panels, using the Printed Solid assembly guide as reference.
Then, replace the original 3D printed bracket on the front right with this 3D printed replacement bracketinserting the longer M3x40 bolt that comes with the enclosure into the top right hole with a 2. Go slow and be careful since the bolt will be going through two threads, the one on the frame and the one on the LCD mount.
The replacement bracket is shaped to fit snugly just above the GLCD, and is included in the images for positioning. Continue with instructions below to install the GLCD below the replacement bracket. Set the bolt aside safely. This may require some force. Adjust orientation so that holes align with frame. Note: For users with the LulzBot Mini Enclosure by Printed Solidplace center section of cover back over printer, and insert the M3x10 mm bolt came with enclosure through the enclosure side, through the printer frame, and into the bottom hole of the cable bracket as shown in image.
The open end of the bracket should be facing the inside of the frame. Adjust orientation so that bracket holes align in frame, and insert both M3x6 FHCS through the frame and into the bracket. The harness cable should feel secure.Your shoppingcart is empty. Continue shopping. Use your forum account to login. Not registered?

The only connectivity option is the 8-bit mode where 8 connections for the data are required between the microcontroller and the GLCD to control the data bus.
To use the KS driver simply include the following in your user code. This will initialise the driver. Optional, but recommend NOT to set. Draw a box on the GLCD to a specific size that is filled with the foreground colour. Draw a line on the GLCD to a specific length that is filled with the specific attribute. Set a pixel on the GLCD at a specific position that is set with the specific attribute. For a KS datasheet, please refer here. See Graphic LCD for details, this is an external web site.

We in MikroElektronika always try to save your development time by making the hard work automatized and offering hardware and software that work in harmony. When we were in the process of writing GLCD libraries, we figured that it was taking too much time to build high-quality graphical applications, and that the most of the process is not so flexible and intuitive.
The Visual GLCD drag-n-drop development environment enables you to spend less time programming, allowing you to focus on functionality and design. Grab the object you need and simply drag it to the location of your choice. Move things around until you are satisfied. Visual GLCD implements functionalities that empower you to handle touch inputs easily.
