LED INTERFACING WITH LPC2148 PDF

Circuit Diagram Components Required Since we are using the LPC development board in this project, some of the mentioned components might already be embedded on to the board. The details of the complete circuit design are as follows. Hence, the connection between the LPC and Bluetooth module requires only two wires. The Bluetooth Module has on — board 3. So, 5V supply can be given to the module.

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. So we have to take care of this fact. Otherwise, you may need to wire up additional circuitry.

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. Here I have presented some differences. It actually depends on requirements, availability of pins and timing requirement etc. The implication is that, 4-bit data transfers will take twice as much time to transfer as 8-bit data transfer. It is a trade off! 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.
