Dear all, I met a problem due to big-endian of 8051. The phenomenon is as follows:
32-bit value A[4] is in XDATA space Ex. offset 0 = 0x12; offset 1 = 0x34; offset 2 = 0x56; offset 3 = 0x78
I used the following to get this value: *((UINT32 *) 0);
For 8051 we got "0x12345678" because of big-endian...
Is there any "efficient"(favor size) method to transform it to 0x87654321 ?
I tried to use: A[0]+A[1]<<8+A[2]<<16+A[3]<<24 but the "machine code" gets bigger...
Thanks !
