Write command data doesn't appear in memory map!?

cbj

Ok I am running ver2.1 of the editor and have a BS2 stamp kit.

I run this code snippet

' {$STAMP BS2}
·
out VAR Byte
·
WRITE 0,"L"
READ 0,out
DEBUG out

When I open the memory map nothing is displayed in the 0 memory position, but the code works (ie there·actually is something at·position·0)·because I get an L in the debug window.

If I run this code snippet

' {$STAMP BS2}
·
out VAR Byte
·
DATA @0,"M"
READ 0, out
DEBUG out

I open the memory map and M is written in the·0 memory position, and it appears in the debug window.

My (dumb?) question:· Both commands write data to the EEPROM, why is it only visible in the memory map when the DATA command is used?

Memory Map will show your EEPROM as it will be downloaded; it does not show it live after WRITE. You can use DEBUG to examine EEPROM while the program is running.
