it doesnt work, no output value from P1 … and your hex file that you uploaded in your website it doesnt upload in to my chip burning mashine maybe its because of mashine but i can not find other mashine can you give me the code that you changed in MicroC?
your HEX of key password has written in keil right ? but in my chip burning mashine can not get it and burn..
but if i change it on MicroC it can but doesnt work. so in below we have a changed Code that i changed and can you check it and make it correct into MicroC … i need your password code of Home security project in MicroC pls help and cjeck this out..

}hi i have a question about proteus7… we know if some pin of chip has high value it showes red color and low voltage is blue color ….But sometimes it showes yellow and gray colors and takes error what does this mean?
ok check this out : first code is fine but second code is not working and shows error like ( not enough RAM ) that is it. but first and second are same , i just added few else if command and others into first code not much so that s second code kk. now iwe have first and second codes below check and help me what is wrong..

} }trying to display with 2 line kk first time i told you i tryed to display using second line and it doesnt work. but now this code is so easy to display and first code is used 11pins of controller, but this guy using 7 pins ..by the way the code i sent today is works if i delete half of them like that :

{Lcd_Cmd(_LCD_CLEAR);
Lcd_Out(1, 1, “xaalga “);}}
} }but i need all codes of them to display nicely kk
kk the program that i got from my friend i didnt ask from him. now he is not here kk so how can i find full it maybe sells right? do you have it? the give it for free kk
ofcourse i did it works. but after i added some else if function then not enough RAM error appears. it is just easy way to display if input becomes high.
hi it is gana i have problem with Micro C here i have a error message ” Not enough RAM ‘? lstr 10_lcd” bolded one is name of the project i am using at89c52 help ??
AND CODE : i am just beginner you know kk what is the ”char txt[100];” can i delete it what does it’s role?

} }kk i almost new that i have changed your project …added LCD and sensors with WIRELESS but i want to make the that code diffrent..like a…in this code we have password only 12345 but i wonna change it whenever i want, like holding (#,*) keys and then restore it what password i wanted . can you help me wth the code ?
it is from your site the guy who made project of home security gave it to me but the name is looks like your name!!!kkk
hi can can you guys convert this code to MicroC? i am learnin Micro C but i can not convert it with my mind pls teach me the way how to changeit…

}hi guys i have almost done but the problem is i can not move the cursor to the second line . i wonna write on second line but i cant.in the lecture C0 Hex move cursor into second line but it doesnt how cani ? help?
hi there thank you a lot i check it out ..but it is not working on my project can you send me your project picture pls? and i tryed the examlpes from MicroC but every code i tryed that not working . when i compile it i having error . i think something is missing in the code written below:
