i'm having a project and it uses LCD and keypad Interface. My problem is I do not know how the data inputted in the keypad will be outputted to the LCD Display.how can it be transmitted to the other device with LCD and Keypad interface too? thanks a lot
ur key pad will send serial(ASCI)data. from the LCD side u need a controller to receive it and process it for display on lcd. regards ratna
"key pad will send serial(ASCI)data" How do you know that? Maybe it's just a matrix keypad? "from the LCD side u need a controller to receive it and process it for display on lcd" There is no problem getting the same 8051 to handle both the keypad input interface, and the LCD output interface.
" I do not know how the data inputted in the keypad will be outputted to the LCD Display" Your keypad interface reads the input data into a buffer some where, then another piece of your code sends the data from that buffer to your LCD output interface. Where preceisely is you problem with this? Do you mean you haven't done the keyboard input interface, nor the LCD output interface yet?
ur key pad will send serial(ASCI)data. 1) What is a microresistor keypad? 2) what brand of Keypad send ASCII data
HI There is some very useful information about LCD at these links. http://www.8052.com/tutlcd.phtml http://home.iae.nl/users/pouweha/lcd/lcd.shtml do check them And as far as the keypad is concerned interface it with the same Ucontroller to which lcd is attached. Check out the pin layout of the keypad. how many rows and columns your keypad have?
