To find out more, including how to control cookies, see here: Hi I constructed the circuit exactly as it is on my simulator and just copied the program and nothing is appearing on the LCD.
Function msdelay has been created to create delay in milliseconds and called frequently in the program, it is called so that LCD module can have sufficient time to execute the internal operation and commands.
Click OK to get the Target1 on the project pane. In this way the total number of pins can be reduced to 6. Comment if you come across any doubts.
This will save us 4 pins of our controller which we might employ it for other purpose. Now click F7 or the Build button to start building intdrfacing.
El retardo es demasiado corto. This pin is used to enable the module when a high to low pulse is given to it. Getting Started with Microcontroller. All the pins are clearly understandable by their name and functions, except the control pins, interffacing they are explained below:.
Code Explanation I have tried to explain the code through comments in code itself. Anybody can send me the programing for lcd interfacing with microcontroller and xbee s2.
Else it executes the next instruction. Thanks for dropping by alselectro! Intertacing shown in the circuit diagram, port 0 of the controller is used for interfacing it with LCD module.
See the circuit diagram for better understanding. DB0 to DB7 are the data pins.

Wih data to the LCD. Ceramic capacitors C1,C2 and crystal X1 is related to the clock circuitry which produces the system clock frequency. And we will set it to 0 if we are sending some command instruction like clear the screen hex code An LCD module can be interfaced with a microcontroller either in 8 bit mode as seen above or in 4 bit mode. The necessary commands for the LCD initialization are defined at the end part of the program.
Pls provide alp programs for LCD interfacing. Can u tell me how to store multiple strings into LCD? VEE pin is meant for adjusting the contrast of the LCD display and the contrast can intrfacing adjusted by varying the voltage at this pin. So first let’s understand the 16 pins of LCD module. Thankyou for taking the efforts! Previous post Next post.
Some important command instructions are given below: As mentioned earlier the 8 bit data is break into two 4 bit data and send to LCD. However 4 bit mode uses only 4 data lines along with the control pins. Feed in the following code:
