Hello every body. I'm new with the 8051. I'm wondering about the STARTUP.A51 file:i read about the possibility to modify it if i'm about to use extra memory to the chip.Could any one help m with an exemple so that i can see what changes could occur? Thanks in advance.
"Could any one help m with an exemple"
Yes, your compiler comes with a whole folder full of examples - funnily enough, it's called Keil\C51\EXAMPLES !!
