Hi,
I'm writing a memory analyzer for Keil uVision to display memory usage instead of having to wade through map files.
I wish to convert a string of the form: 0xhhhhhhhh to a long integer so I can do calc's. I also wish to convert the result back to hex strings.
Of course I strip off the 0x and make the remaining 8 char's upper case.
The problem I have is I don't get the answer I expect: viz
Input 0x0807dc74 = 134,732,916 decimal
But the output I get is 8,597,713,124 decimal = 0x2 0076 B0E4 in Hex
I have fiddled with the Endianess and tried bytes and strings, but with no success.
I feel it's got something to do with two's complement, but I am not sure what. It is making my brain hurt.
Can someone help me.
The code in question is:
