In most of embedded systems applications, the need for a display is must. We can use display to represent text, numeric data or even graphics. The JHDA has 16 pins and can be interfaced into 4-bit or 8-bit mode. We will get into that in a minute. This LCD controller can be operated in 4-bit or 8-bit mode.

In most of embedded systems applications, the need for a display is must. We can use display to represent text, numeric data or even graphics. The JHDA has 16 pins and can be interfaced into 4-bit or 8-bit mode.
We will get into that in a minute. This LCD controller can be operated in 4-bit or 8-bit mode. You can easily buy this cheap china made LCD in almost every supplier shop. This voltage across VEE pin defines the contrast. In general case this voltage is between 0. It will be recognized as data.
The commands and data can be transferred through these pins in either 8-bit or 4-bit mode. When operated on 5V a 10E resistor should be connected in series to this pin.
As we all aware that almost everything in this field is trade-off! We have to decide on an application by application basis, which is best approach to take. We need to supply commands in a given order to the data pins with small amount of delay in between to initialize LCD properly.
These commands are listed in given table. We also have presented fully functioning program and free to download project. Since explanation of code is not in the scope of this tutorial, we will soon upload videos for code explanation. If you have any questions then feel free to leave a comment. Remember Me.

lcd interfacing with ARM7 ( LPC2148 )
They have become very common and have taken a giant leap in the screen industry by clearly replacing the use of Cathode Ray Tubes CRT. All of us have seen a LCD, but no one knows the exact working of it. Let us take a look at the working of a LCD. These modules are preferred over seven segments and other multi segment LEDs.

LPC2148 – LCD Interfacing
As per the name the 2x16 has 2 lines with 16 chars on each line. Here each character is displayed in a matrix of 5x7 pixels. Apart from alphanumeric chars it also provides the provision to display the custom characters by creating the pattern. Below schematic shows the minimum connection required for interfacing the LCD with the microcontroller.
