Sir, I have installed keil Uvision 5 on my laptop ,but when I start debug the function key f11 is not working it is not step down the program using F11 what is the prblem and how do i rectify it.
Which version of C51 are you using ?
Could you try the same with latest C51 version ? www.keil.com/.../
If it's the same, try a different keyboard/PC.
Click the icons instead?
Click the icons instead? I'm, pretty much, an "Icon guy" the guy next to me is a "function key guy". We ar both totally lost when looking at what the other one is doing and both have to slow down dramatically when asking for help.
