Digital Code Lock With 3310 LCD

Its working!!!

Thanks to everyone who helped me!!!

So here is my solution: Im cutting the images into 2 party to be desplayed as one. I know that there has to be another way, but I didnt find it The simulation work fine... Lets wait for the IRL-version

Okay - feel free to tryout -

" * " to start
" # " to enter after code-request
veryfycode " 1234 "
mastercode "12345 " written onto blocking-image

So far - so good.

Have a nice weekend!

job well done wawa..!!

btw i tried fast LCD but i have doubt. how do i convert this this to hex? can i directly chage it to lets say 0x08 from &h08?

tae = 128, 8,   ' Image Table Name, Xbytes, N of Lines, 1026 bytes
&h00,&h00,&h00,&h08,&h00,&h00,&h00,&h00,&h00,&h00,&h04,&h00,&h00,&h00,&h00,&h00,

Yes - I did it with word.
Keep focus on changing the picures attributes to greyscale before converting.

well problem is you declared variable 'i' as unsigned char so it never goes beyond 255 and your loop expect it to be 504

declare i as unsigned int and see the result with code i posted let me know when its done. good luck!!

Hey!
I didnt change the code yet. Semms to wrk but now my ego starts to fight to make a bigger job... well - only some hours of work and some money to spend but to let the ego grow.... when its done

Seriously: I am thinking about implementing this codelock as start of a touchscreen-based interface...

hahaha - I need more then halp, I think

Thanks for your starting-up help till now

Dear MAJOKA
I try attach with 93c46
Without 3310 lcd work but with 3310 lcd not work plz ones again help me
thanks

93c46 is an serial eeprom of 3 wire
why u need to connect it ru need to save password
u want to say that ur code is working with 93c46 but when no 3310 lcd
am i right ?

Yes I want save password in eeprom
code is working with 93c46
but I add commands in code for 3310 lcd then 8951 pin no data send to 93c46

I am checking in proteus

hello tahirmaqsood
upload Proteus files for my easiness
it mean u facing the problem only when u attach memory to 8051
then 8051 not store data on memory in normal
case when simple 3310 lcd is connected without memory its work well

store a password in an array as in previous codes u do
after that when user press enter key then store this array into eeprom at once that will be an easy approach
