Syntax
SUB
FREAD ( FlashAddr,
Destination, size
)
Destination = arrayname | stringname
size in
bytes
Description -- added version 7.13
The builtin subroutine
FREAD copies data stored
in the Flash memory to the Destination array, for size
bytes. When a string is
used, it is treated like a byte array, not a 0 terminated
string
Example
' simple example of write and read
DIM A(511) as string
DIM B(511) as string
...
WRITE (&H6000, A, 512) ' this will erase
the &H6000 sector, as its the first encountered
WRITE (&H6200, A, 512) ' no erasure is
required, as it was erased in the last call
FREAD
(&H6200, B, 512)
...
WRITE (&H6000, A,
0) ' this forces an erase of sector &H6000,
needed as it was the last sector erased
WRITE (&H6000, A,
512)
...
WRITE (&H6000, A,
512) ' as the same block is being written it will
automatically be erased
WRITE (&H6000, A, 512)
