Running out of space in internal Data
#55022 - Thu May 08 2008 01:24 AM

Hello,

I am using a P89C51RD2 but running out of space in the internal data. How can I use the CODE or XDATA memory space to create an array?

Cheers
Paul

The memory usage is shown below.

SEGMENTS Name Load Length Top Selector Space Class

vectors 000000 0000FE 0000FE 0 0 CODE
rbit 000020 000060 000080 20 1 BITSEG
idata 000080 000062 0000E2 80 1 DATA
data 000100 0034F7 0035F7 100 0 CODE

UNUSED ADDRESS RANGES

CODE 00FE-00FF
35F7-FFFF
XDATA 0100-02FF

Why not hop across to the HI-TECH C PRO for Silicon Labs 8051 beta forum and try out the new HI-TECH C PRO compiler for 8051? It automatically allocates data into the different address spaces in the most efficient way.

The beta version compiler is a free download right now.
