KEIL-BANK分页(H00，H01 ... H0x)

对C51而言，生成的HEX文件是有体积限制的，如果ROM过大，那么就要用到分页技术将HEX分成几个文件

具体做法简单点来说，如下：

===================================================================

1.找到L51_BANK.A51文件加到工程中

2.找到STARTUP.A51文件最后 EXTRN CODE (?B_SWITCH0) CALL ?B_SWITCH0 ; init bank mechanism to code bank 0 原来是注释掉的，恢复有效

3.剩下的就是设置了，看下图

=================================================

更啰嗦的做法见第二个参考链接

======================================

再贴一个合成脚本：

在KEIL的OPTION的USER页下，最后一栏：RUN AFTER BUILD中加入编译完成后要调用的动作: Merge256K_4M.bat

然后看这个bat的代码：

del hex\sparrow.H00

del hex\sparrow.H01

del hex\sparrow.H02

del hex\sparrow.H03

del hex\sparrow.H04

del hex\sparrow.H05

del hex\sparrow.H06

del hex\sparrow.H07

del hex\sparrow.H08                先删除原来的分页文件

@echo off

copy output\sparrow.H00 hex\sparrow.H00

copy output\sparrow.H01 hex\sparrow.H01

copy output\sparrow.H02 hex\sparrow.H02

copy output\sparrow.H03 hex\sparrow.H03

copy output\sparrow.H04 hex\sparrow.H04

copy output\sparrow.H05 hex\sparrow.H05

copy output\sparrow.H06 hex\sparrow.H06

copy output\sparrow.H07 hex\sparrow.H07        将新的分页文件复制到指定地址

HEX2BIN /Q /L524288   hex\sparrow.H00 hex\RTD2668.BIN

HEX2BIN /Q /O65536 /M hex\sparrow.H01 hex\RTD2668.BIN

HEX2BIN /Q /O131072 /M hex\sparrow.H02 hex\RTD2668.BIN

HEX2BIN /Q /O196608 /M hex\sparrow.H03 hex\RTD2668.BIN

HEX2BIN /Q /O262144 /M hex\sparrow.H04 hex\RTD2668.BIN

HEX2BIN /Q /O327680 /M hex\sparrow.H05 hex\RTD2668.BIN

HEX2BIN /Q /O393216 /M hex\sparrow.H06 hex\RTD2668.BIN

HEX2BIN /Q /O458752 /M hex\sparrow.H07 hex\RTD2668.BIN

用HEX2BIN将HEX分页合成一个BIN文件
