where is i can download example multitasking program? . i have 8051 microcontroller i want to learn for my thesis. thank you.
I followed with any advices,i read "uVision Getting Started guide " and working through the example projects (RTX) in it. i use "serial windows #1" it is work. and i test example program by download to my 8051 microcontoller board. it is not work. what is it wrong?
"it is not work. what is it wrong?" I don't know. Nobody can guess what is wrong based on the information you have given. Describe in detail the steps you have taken and maybe someone will be able to help. Stefan
"I followed with any advices,i read "uVision Getting Started guide " and working through the example projects (RTX)" The advice was to go through all the examples - not just the RTX one. You need to begin with the basics before jumping into the complexites of RTX. As I said before, It's no good trying to build fancy multitasking systems if you don't have a good, solid foundation in the 8051 architecture & tools! Start by writing a very simple "Hello world" application to verify that you can build, download, and run anything at all!
i compiled example program (Traffic). i download Traffic.hex to 8051 MC board. it is not work?? (i don't modified program) My target is use 8051 MC board insteard PC. what is it wrong? or i work wrong. Can you advise me? thank you.
When I suggested, "Start by writing a very simple 'Hello world' application to verify that you can build, download, and run anything at all" did you do it? Are you confident that your hardware is working, and that you can build, download, and run anything at all? There is no point going any further until you're sure that you've got the basics working!
i tested example program(hello.c).it can load and run on my 8051 MC board.but when i load multitasking program (traffic.hex)to my board it is not run. why? please advise me. thank you.
"i tested example program(hello.c).it can load and run on my 8051 MC board." Good - so now we can have at least some degree of confidence that your build process works, your downloading works, and your target works. Of course, this is not an exhaustive test - so there could still be problems lurking... "but when i load multitasking program (traffic.hex)to my board it is not run. why?" It is impossible to answer that from the information you have given - ie, virtually none at all! * Are you sure that this particular example should work on your hardware? * Are you sure that the build completes fully & successfully - do you get any error or warning messages? * Are you sure that the download succeeds? * What do you expect should happen when the download completes? * What actually does happen? Have you spoken to your tutors about this? They are in a far better position to help you than complete strangers far away who don't even share your first language!
Thank you every advices. If i have another problems i'll post to you again. Thank you again. piyata suntagit. My country is Thailand in Asia whitch beutiful country. Are you know my country?. bye.
Can you tell me .Where i can down load Keil c51 version 2 or 2...? thank you.
"Where i can down load Keil c51 version 2 or 2...?" You can't. Anyway, why on earth would you want to do such a thing?! You said you're new - so what's the point in starting with such an ancient museum piece?! Take a look through recent threads and see the problems some people have getting even v5 to work on modern systems - imagine what it'd be like with something as old as v2. Might not even work on Win3.1?! ;-)
