Maybe this is a simple question, but I just couldn't figure it out. Can someone tell me how to place a constant variable into the specific ROM area? I would like to be able to set a constant value at a particualr ROM area and use a pointer to get it whenever I need it. Cheers, Tang
Why does Keil have this restriction? You can do this with Raisonance and I would like to have my code be compatible with both. For Raisonance you just use: at 0x803d code char my_char = 0x55; I don't need to have a variable name created, but I would like to be able to set a byte that configures the hardware. This is a hardware configuration byte that needs to be programmed when the program is loaded. If I understand correctly there is no way to add a single statement to the Keil C program for this function. I have to link an assembly language file to do that with Keil. Is that correct?
"Why does Keil have this restriction?" Although it seems a simple enough addition apparently it will involve a major rewrite of part of the compiler. You can put the 'variable' in its own 'C' source file then link that as a 'user segment'. There's an example in the knowledgebase somewhere.
