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 find it curious that the App Note's method (using the OVERLAY command) doesn't even make it to your Top 5 Workarounds."
but why use such a simple solution when more convoluted ones exist? how can we possibly justify our existence if a simple OVERLAY command does what we can do in a month's time?
not to mention our ego for sophistication.
