Establish Trust Want less hassle adding authentication and encryption capabilities to your design? Wirth is always good reading, and I had forgotten that article, but will take it out again.

Read-Only Author But my implementation requires function pointers.

Development Tools

I’ve got a copy of his articles here somewhereshould someone need them. But the problem is still present. Wishing you all the assembleru of the season and happiness throughout I solved part of my problem. This also affects how you prepare parameters to be passed. It’s so easy in assembleur why is it so difficult in C?


First I have studied the microcontroleur himself, after I have made a lot of programs in assembleur with Keil, and no problem. Second question would be: You can pick up the bare bones of one from many books or GPL source. Producing optimised machine code for sasembleur CPUs is very difficult. Explore an application Want to see an easy way to get there?

Is there a way to configure the memory? Before you set out on you epic quest, try converting the following code to assembler for your target CPU and you may get a feel for what lies ahead.

Andy Neil Perhaps it’s time to stop and go back to basics. It’s just a solution to trying to the C programming language to write “assembler” code. However, the C language is a high level language. Important information This site uses cookies to store information on your computer.

Maybe should I tell the microcontroleur where out where to store the “unite” variable. My answer isn’t a solution to your problem. When we create a software on a PC, windows assembbleur automatically the place where variables are stock in the RAM, but maybe with microcontroleur it works diferently.

We offer a variety of ways to find the solution you need. Start developing Compilers, programmers, debuggers, code configurators, analog design tools and more.


Is this going assemb,eur conflict with keeping your result in a register. So – that variable “unite” is stored someplace where it gets constantly overwritten. HTM Application du Z I’m french, so sorry for my english. Compilers, programmers, debuggers, code configurators, analog design tools and more.

The PC display “Serial number: BUT now if I swap the variables at the time of the statement, it does not work anymore.
