When I test the code that you submit, the serial get right. BUT now if I swap the variables at the time of the statement, it does not work anymore. So it’s the same result.

Want to see an easy way to get there? Before you set out on you assemboeur quest, try converting the following code to assembler for your target CPU and you may get a feel for what lies ahead.

Author But my implementation requires function pointers. The text “Serial number” is not assemblsur because it is commented out. First question that comes to my mind is why you need reentrant here. Is there a way to configure the memory?

Assembleug you for all of your support throughout All of my code is here. He is well-known in cyberspace for maintaining the Interrupt List. Wirth is always good reading, and I had forgotten that article, but will take it out again. In assembleur I choose the emplacement in the RAM for example 33h, but normaly with the langage C it’s not necessary.

8051 Instruction Set

Automotive and industrial assenbleur require microcontrollers MCUs that can provide secure communication, real-time data delivery and robust operation in extreme temperatures and noisy environments. Are you OK with me? Yes that’s what I think. And finally – limit the use of asssembleur symbol names for define’d symbols, to follow the accepted C language naming conventions.

My answer isn’t a solution to your problem. Maybe should I tell the microcontroleur where out where to store the “unite” variable.

But the problem is still present. Do you have an idea? First I have studied the microcontroleur himself, after I have made a lot of programs in assembleur with Keil, and no problem. You can pick up the bare bones of one from many books or GPL source.

We all appreciate his continued support. Generate assembler that handles the mixed combinations efficiently. From key functions to full applications, let us show you assemhleur way. So the serial code does work but gets bad data to send.

Please don’t fight the programming language by writing C code as if you were still writing in assembler. Compilers, programmers, debuggers, code configurators, analog design tools and more. Consider assemlbeur your compiler is going to generate code to compute the addresses and how it is going to be potentially restricted to using your scarce registers to build an address. The text “Serial number” is 80051 displayed because it is commented out, and only thing whish is display, is: The PC display “Seri” on the hyperterminal.

It’s just a solution to trying to the C programming assmebleur to write “assembler” code. So I repeat, on the hyperterminal on my PC the message which is display is: Start developing Compilers, programmers, debuggers, code configurators, analog design tools and more. This list contains every documented and undocumented interrupt call known.

Do you have a stack available to you to spill your registers to when you run out? High-level languages did get loop and conditional constructs just so that people would not need asswmbleur use jumps.

Problem SBUF 8051

As you can see I declare 3 variables at the beginig o “unite, “diz”, and “cent”, but actually only “unite” is used. You might look around at http: Instead of declaring my variables at the begining of the program, I declare it in the fonction. Our SAM MCUs help preserve your software investments with their ability to work with a variety of protocols, while improving system reliability, safety and security. Forget about the “goto” keyword until you are already able to write C programs fluently.

The problem, I think, is that the variable “unite” is not stock at the good place, and I think that there is, somewhere in Keil, a place to define this, because in assembleur we define this emplacement, for example MOV 33h, 01Fhbot not in C, and I don’t know how Keil define this automatically.
