I am using an 8051 (C51/BL51) with no off-chip memory. I have two functions with parameters:
void Detect( U8 iLed )
and
static U8 INHSampleHandler( U16 u16Sample )
Now I understand that Keil will allocate a variable (in DATA) for these. The problem seems to be that the locator is using the same memory location for both. I cannot understand why.
Below are excerpts from the scratchpad showing 2 "D:0026H". These are the only places these symbols are declared. Any ideas what I'm doing wrong?
Thanks, Jeff

I've tried to make my example more "complicated" but that darn optimizer is too smart
try optimize = 2. this is basically variable overlay and nothing else.
to the homewrecker and the sardine: please not the word basically
Erik
"please not the word basically"
is it too much to ask that you write complete and comprehensible sentences, erik?
Folks, I think you are gallantly galloped way, way off the beaten path if the original poster is posting summary's like "A helpful post"
I love a good name calling and the pedantic arguments session, but maybe it would be better to create a new thread next time we want to do this? I do not think it was benefiting the OP.
Scratch that, I bet we can get this done without the name calling, especially the dreaded "s" word (sardine).
