While using the simulator, the values of i in the serial window are shifted by left 8 bits.
#include "stdlib.h" #include "stdio.h" #include "reg51.h" void main (void) { unsigned char i; SCON = 0x50; TMOD |= 0x20; TH1 = 221; TR1 = 1; TI = 1; for (i = 0; i < 8; i++) { printf("%x\n", i); } }
"I HAVE GOT 2 HOURS LEFT TO DO THIS"
A pity -- time is running out. But look at it this way, after time has run out and you fail, you'll have time to reflect on this experience, reread posts, and realize "If I hadn't solicited all those wasted replies simply on the topic of SHOUTING, I might have gotten a legitimate reply on my topic exactly or have been given guidance on how to use Google to effectively search for solutions to my problem. Dang it, I only I had listened and acted accordingly..."
"I TRY GOOGLE AND MICROSOFT BUT CANNOT FIND ANY CODE THAT WORKS"
Hmmm ...
Not sure about Google code, but I have sometimes found myself wondering if Microsoft code works!
Oh yes ... a hint to the screamer
I think you mean packed BCD - Try a search for that!
"DOES ANYONE KNOW THE ANSWER?"
Yes, I'm pretty sure we all do. Microsoft probably isn't the place to search. Have you actually typed the three characters 'B', 'C', and 'D' into Google's search text entry box?
He does not know what BCD is, he insist on shouting, he wants to get a diploma.
I hope anyone trying to 'help' him will end up sitting at the desk next to his when he 'get' his diploma and get hired.
I, am perfectly willing, as we all should be, to help anyone trying to get through school, but 'helping' someone get thought school without having even an inkling of understanding of the subject is very counterproductive.
I, once, was given (by a HR that did not believe in engineers interviewing candidates) an assistant that as the first thing he did put up his freshly minted PhD diploma on his office wall. I gave him a piece of code to look at (saying this is the style we use here) and his first question (1/2 hour later) was "does db mean 'double byte'". The 'ad' for the job specified, among other things, "fluent in '51 assembler" and HR assured me that he was (they read what his diploma supposedly ment).

"Is your friend spending his time on another forum?"
They're a tag-team. The friend is the one doing the coding since it requires the ability to use lowercase.
It takes no longer to type politely than to shout.
You want this for free - the least you can do is to ask nicely!
If you won't do that, I won't reply.
I wonder why the text "what is bcd" is such a good search term to google on. Might it be because it tells exactly what BCD numbers are, and how they are stored, and how to convert back from BCD to either a binary number or a decimal number?
Did you get your code from a friend in the same class?
Are you expecting to send in the same solution?
Do you think your teacher likes to see two identical solutions?
Is your friend spending his time on another forum?
Doesn't it feel good after having really spent some time solving a problem?
I HAVE NO TIME
IF YOU KNOW PLEASE TELL ME ANSWER
What would be the point in telling you? You clearly aren't listening to what you're being told!
How many times does "Don't Shout" have to be said to you before you will stop shouting??
I will give you some tips if you will stop shouting.
I DO NOT UNDERSTAND HOW TO PACKET DATA INTO BYTE
ANYONE KNOW?
Which part of "do not write in ALL-CAPITALS" do you not understand?
I mean, "do not write in ALL-UPPERCASE"
I LOOK ON GOOGLE FOR BCD AGAIN AND FOUND DATA ON PACKET BINARY CODED DECIMAL
THE CODE CAM FROM A FREIND WHO SAYS IT WORKS BUT I TRY WITH (IE) 120 BUT IT DOES NOT PRINT 120
I NEED TO GET CODE WORKING
PLEASE WHAT IS WRONG?
"WHAT IS WRONG?"
1) The code is lousy!
2) You still haven't learned what BCD numbers are!
Try one more time to google for BCD numbers. How can you know when a solution works or not, if you don't even know what the expected output result is?
By the way: Please post your address, and you'll get a visitor that will rip the caps-lock key from your keyboard - and every keyboard within a 100m radius... Upper-case text represents shouting, as already told a number of times in this thread. Are you dense?
