My progam 'DATA' segment is too large, how to solve it ?
First, you need to read the uVision Getting Started guide, and work through the example projects in it.

You need to read the following documents - commonly referred to as "the bible" for the 8051 - then you will understand where all this DATA, IDATA, XDATA and stuff comes from: Chapter 1 - 80C51 Family Architecture: http://www.semiconductors.philips.com/acrobat/various/80C51_FAM_ARCH_1.pdf Chapter 2 - 80C51 Family Programmer's Guide and Instruction Set: http://www.semiconductors.philips.com/acrobat/various/80C51_FAM_PROG_GUIDE_1.pdf Chapter 3 - 80C51 Family Hardware Description: http://www.semiconductors.philips.com/acrobat/various/80C51_FAM_HARDWARE_1.pdf
My progam 'DATA' segment is too large, how to solve it ? excellent! do not respomnd to previous posts, just lop more stuff in. There is no way this forum can relieve you from the task you evidently dread of reading the manuals. Read the documents Andy refer to and then come back. Erik
