I am currently doing a project using HD44780 20x4 lcd display and PIC18F252 to produce a simplistic Battery monitor. At the moment all I wish to achieve is taking a voltage from a shunt amplified to around 3v and the voltage from the battery reduced to 3v and display these on the lcd display. obviously the voltage acros the shunt is (...)
Hi all,. How to interface lcd with PIC microcontroller. what is the functions to be used . i am using JHD204A 20x4 lcd display and PIC18f452.Thanks & Regardssivakumar if you want to do under CCS C please see the link below. even otherwise , perhaps this software approximately guides you towards you

Hello dears! I wana display user defined functions on Alphanumeric lcd(20x4). For this, i have to use CGRAM of lcd. I think CGRAM address starts from 0x40 to 0x7f. So i have to store the user defined characters in these locations, then to display at lcd.. When I wrote a code and stored a user (...)

Hi, I need some lcd codes for 8051 and AVR microcontrollers in C. The code should be very portable, and the delays should also be independent of oscillator frequency to ensure portability. and the library should have all standard C functions like printf, puts, gotoxy, as well as additional functions like cursor on . . . N.B. I actually (...)

Hey all, From what I see there is nothing wrong with this code. It is for a hd44780 lcd, and this should initialize for 4 bit mode and then turn on the display/cursor. I get a bunch of warning for parameters without init value having a constant value of zero or something. Aren't initial values for register types always zero? I would appreciate
hi, i have problem in changing 4 bit lcd module to 8 bit lcd module. i have source code of temperature sensor using ds1820 which display temperature on 4 bit lcd module. however, my lcd can only run on 8 bit module. can anybody show me how to change it? i am using ccs c compiler. i attach here with (...)
