I have a task to make a device like a calculator, it has a keypad and LCD display... this device has a code inside, then when I press the keypad and enter a six digit combination, and if it will coincide with the code inside of that device, I can now enter to the next level.... it is like a password program but I should group it to 60, 1 group will have 6 digit combination.

is there any process related to this each combination of logic???

mean you have 2^6 combinations that are 64 what will happen if you give a code from keypad and it will match in the code in your controller???

ah okay hehe you mean inside the device there are 60 combination of code and each combination is 6digit.. am I ryt? yeah its like a password based system.

if it will match, I can now put a number... this type of application can be used in an industrial plant.... those 60 groups of numbers will correspond to a certain variance of the product, and when I enter the 6 digit numbers then if it will match to a certain variance, I can now put the number of that variance being produce. Example 146854 <Enter> 13,000 >> then It will automatically save to a computer>> the variant code and the number of it being produce.

But are there any of you, that knows how to put seven segment on 8051 and interface it on the computer with a corresponding program...? Do you know how to program it? (The source code for that password kind)

i am doing a countdown timer with 8051 for my project, unfortunately our professor had to take a leave of absence before he could teach us most of it.. can someone explain the .asm code of it for me?

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.
