Having trouble starting a project

I start uVision3 and clicked 'New uVision Project' from the Project Menu. A 'Create New Project' window appears. I enter the name of the project (LEDTest) and clicked save. Then a "Select device for Target 1' window appeared. I then double-clicked on Atmel and chose the AT89C55WD as the device and I clicked OK. Then a window saying 'Copy Standard 8051 Startup Code to Project Folder and Add File To Project' appeared and I clicked yes. As soon as I did that, the Project Window displayed. On the 'Target 1' folder are 3 red dots which I know means there's something wrong. I haven't even written code yet and I'm having problems. Does anyone knows how to correct this problem?

  • " I don't know why "

    Because this is the startup code for a 'C' program; so it expects to have a 'C' program to jump into - but you haven't provided one!

  • That explains it. I'm such an idiot. I thought that since it had an A51 extension that it was assembly. Are there any other files that I could add to group 1 that would give me other features that I don't know about? Do I have to put an INCLUDE file at the beginning of my code or does uVision3 do it automatically since I selected a device when setting up the project? I have a lot to learn.

  • "I thought that since it had an A51 extension that it was assembly."

    Yes, it is assembly - you can open it and look it at - and that is why it has the A51 extension.

    But its specific function is to prepare the system to run a 'C' program, and then to call that 'C' program.

    "Are there any other files that I could add to group 1 that would give me other features that I don't know about?"

    If you add any random file to any group you will most probably get features that you don't know about!

    "Do I have to put an INCLUDE file at the beginning of my code"

    No, you don't have to - but it is usually a good way to proceed.

    "does uVision3 do it automatically"

    Not automatically - but it does give a menu item to make manually adding the "standard" processor include file a one-click operation!

    "I selected a device when setting up the project"

    That's how it knows which include file to offer in the menu option.
    (also how it knew which startup file to offer).

    "I have a lot to learn."

    Indeed. And it would probably be a lot more effective if you were to take some time to sit down and do some study rather than just stumbling from error to error.
