Making “The LCD Expansion Board” for PIC18F4520

In this tutorial I you show you how to make a very useful expansion board for our PIC development board. It will be a Do It Your self (DIY) LCD Expansion board. The expansion board can be plugged into the PIC development board to add 16×2 Alphanumeric LCD Support to it. Since LCDs are required in many projects and experiments it will be a very helpful board. I recommend you to read the LCD Interfacing Tutorial before you proceed. It will give you an Idea how LCD is connected to PIC Microcontrollers. So lets start! Schematic for LCD Expansion Board. Fig.: LCD Module Interface with PIC Microcontroller. The board is very easy to make as the MCU core unit is already done for you. So you need to just care about the LCD part. It consists of the 16×2 LCD Module and A variable resistor (10K) only! Optionally you can add a 47ohm series resistor with the LED backlight of the LCD Module, to enable the backlight. The variable resistor is used to adjust the contrast of the module. If NO text is displayed adjust this pot. All I/O ports and power supply is available at the top of expansion board. Fig.: A blank expansion. As you can see the top row in the board lists all I/O port of […]

PIC Development Board – Expansion of Board

The PIC Development board from eXtreme Electronics has the feature of connecting add-on boards, like user interface board or a motor controller board. You can also make your own expansion board. Actually the board has the ability to connect a prototyping area where you can create your project specific circuit while the "basic" environment for PIC resides on the Development board. Fig.: Replaceable Prototyping Area   In this way many project can be created and kept for future use. Each project resides in its own board when you need that simply pair it with development board and the project is up and running! No messy wiring! Preparing a Veroboard for connection Take a general purpose PCB (veroboard) and solder a 40 PIN right angled burg strip connector in one end. Fig.: Replaceable Prototyping Area Now the it is ready to plug into the Development Board. Fig.: Replaceable Prototyping Area   After you connect your prototyping area to the Dev Board all PORTs of PIC MCU and Power Supply becomes available in the veroboard. Here you can connect all sort of components required by your project. It is very easy to remove the prototyping are and replace it with a fresh new one for another project. Thus a single development board can be used for many different projects. The 40 PIN […]

PIC Development Board – Introduction

Thanks for selecting PIC development board from eXtreme Electronics. Now lets get familiar with this powerful and easy to use system. Introduction This board will help you build and test any project with PIC microcontroller quickly and easily. It can be used to work with any 40 PIN PIC micros. The board provides the basic environment for the PIC to run. The great advantage of the design is replaceable prototyping area. All ports and power supply is available on 40 PIN female connecter. You can easily attach a normal veroboard with help of 40 PIN male headers. Now all PORTs of MCU is available on the veroboard where you can design the rest of your project. In this way you can create many different project with same development board, you just need a blank veroboard. By using this technique the "rest" of your project and the development board are paired firmly, both electrically and physically, yet flexibly separable! Features Incircuit Serially Programmable with eXtreme Burner – PIC. PIC 18F4550 Included USB 2.0 Support Running @ 48 MHz (12MIPS) with 20 MHz crystal. (Using on chip PLL) Inbuilt 5V regulator with reverse voltage protection Power Switch (on/off) Power LED Reset Button RS232 Interface with DB9 male connector. 2 x Extra 5v Out All ports on linear 40 pin female connector. Replaceable […]
