Please spare my poor english language skill T_T less than 5% of people in my country can speak english.



I just notice this line.

It's an honor to hear someone said this to my easy, simple, dirty, absolutely unoptimized code. (Does my code really have some expert looks in it?)

In this website I've read every page of 8051 tutorial, RTC tutorial, LCD programming. This program is my first attemp in both assembly and the 8051.

Yes, I assembled it myself with the help of many ppl in this forum. I start posted here around 1 week ago when I've never write any assembly code yet. If you go through page 1-2 of this forum, you'll find several thread started by me. All of them are about making this program work.

What is this program really do? My goal for my first program is to make the 8051 do all of this.

1.Real Time Clock. (completed)
2.Stopwatch (should be completed tonight, thanks to this thread)
3.Alarm clock. (completed)
4.When you woke up, you need to enter password to stop the alarm clock. (completed)

The password will be generated on LCD display every 1 minute. The generated password is ranged between 0-15. There'll be 4 password input buttons for inputting password in binary format.

Forexample if "9" is generated, you have to convert it to 1001 and press the first and fourth button in the same time to stop the alarm.

This'll ensure that you are gonna woke up completely.

In the next version in this program :

1. Have 8051's alarm signal drive the play/pause/eject buttons of the CD-ROM drive. So the first track of the music CD inserted will be an alarm.

2. I really want to make something that function like large buttons that won't crash even when you step on it(perhaps using papers that they use to cover roast chickens which can leads electricity). And write a code that you'll have to enter password 5-10 times to stop the alarm. So you'll have to wake up and dance on those buttons in order to stop an alarm.
