Hi everyone
I m workin on AT89c52 using C but i am facin a problem with pointers.I am declearing a pointer
unsigned char *ptr; unsigned int Address; ....... ......... void main( void ) { ...... ....... ptr = 0x2233; // Its works Address = 0x2233; ptr = Address; // error 214 illigel pointer //operation ........ }
why is this error
why is this error If you read the error message, you will see what the problem is: Address isn't a pointer...
If this does not help you to solve the problem, you should start with learning C basics.
You also need to understand that pointers are somewhat "special" in C51, to cope with the 8051's somewhat "special" memory architecture: http://www.keil.com/support/man/docs/c51/c51_le_ptrs.htm
If you didn't realise that the 8051 has a somewhat "special" memory architecture, then you also need to do some basic study of the 8051 architecture:

For some suggested books on both programming in general and the 8051 in particular, see: http://www.keil.com/books/
