#37228 - RE: DATA to XDATA problem |
<html>
1. U8 u8Array[10]=0; the array is declared and allocated and all the values are set to 0. i doubt the compiler will let you do this; if it did, you'd be allocating u8Array and then screwing it up by pointing it to address zero. use: U8 u8Array[2] = { 0, 0 }; 2. U8 *u8Array=0; What will be set to 0 ??? the pointer u8Array will be set to point to address 0. 3. the Keil example : unsigned char xdata foo; unsigned char xdata *foo_ptr = &foo; The array foo_ptr is declared and initialized with the value contained in foo. that looks wrong; it looks like foo_ptr is being initialized with the address of foo, not the value contained in foo. james |
