sir, i am tyring to communicate rtc and 8051. But my code is not working properly. can u send me the source code
If you're using an 8051, why have you selected your toolset/architecture as 80251??
"my code is not working properly. can u send me the source code"
If it's your code, then you must already have the source code for it - surely?!
