I tried it but, it didn't. Please help me,, do you have a sample program there that will act as a password. I tried to use the serial interrupt, but it didn't affect.

i do not understand what u want to do exactly
in password what is the role of serial port

okay let us not discuss this serial, but will you teach me on how to make a simple password code that can be simulated by keil?

keil can't simulate a password type code because it does not have an keypad
use Proteus for simulation it will save ur work and time
first learn two things how characters displayed on lcd and how keypad interfaced and coding
here is a book
read it so u get basics of these things
download from here

I am here in the middle of nowhere. I don't have a freedom on this computer. Yes! I have a computer here in the office, but, with a no freedom on installing software like Proteus or even download the file that was given by sir majoka. I don't know how I can start this project... sorry that I am telling you this here, but I am so pressured now.

Yeah.... is it okay?

onyot, base on your concept that u want to implement, serial function is not needed. Stick on the idea we talked to u n the previous pages.

F u are task to make that project then y dont ask them to have an administrator account? Or u can use portable applications that doesnt need admin prevlge.


Do follow what we suggest 2 u onyot so that we have organize ideas to discuss here. If u do that u can finish that n 1week excluding the hardware.

hi onyot.josephian
with out keil installation u will be not able to make a code
however a portable Proteus version can be used
even keil can also be used when it install in c drive it make a keil folder there uv2 and uv3 folders are
these folders has direct shortcut to keil

hello! newbie here. i am kind of a guy who hates using ready - made existing libraries, so this helped a lot as i was trying to control and write to a character lcd display. however, i can't figure out how to set the cursor position. for example, i want to set it to the 5th column in the first row, so position 5. so according to the table, i am sending 10000101 on the 8 data lines of the lcd (register select pulled low). the cursor does not move there however. and i cant move the cursor left or right too. is it something wrong that i am doing? thank you.
