LCD顯示實(shí)驗(yàn)用例

目錄文件結(jié)構(gòu)：

lcd_test
        ├─ main.c              C語言主源文件
        ├─ bmp.c               光標(biāo)圖案源文件
        ├─ bmp.h               光標(biāo)圖案頭文件
        ├─ lcd.c               LCD顯示函數(shù)源文件
        └─ lcd.h               LCD定義頭文件


＊ 在RAM 中調(diào)試時(shí)，修改工程配置項(xiàng)
      Project >Settings ->Assembler >General category >Predefines: set as
                       
      Project >Settings ->Linker >General category >Linker script file: set as
                      ..\common\ram_ice.ld

＊ 燒寫程序到FLASH
 1、修改工程配置項(xiàng)
    i）在Flash 中運(yùn)行程序:
       Project >Settings ->Assembler >General category >Predefines: set as 
                      （不用定義任何標(biāo)號(hào)）
       Project >Settings ->Linker >General category >Linker script file: set as
                      ..\common\flash.ld

    ii）拷貝Flash 程序到RAM 中運(yùn)行: 
       Project >Settings ->Assembler >General category >Predefines: set as
	        EXEC_FROM_RAM=1
       Project >Settings ->Linker >General category >Linker script file: set as
           ..\common\ram_ice.ld
   
  * 如果要把程序存放到Flash 中的非0x0 地址上運(yùn)行，
      請(qǐng)修改編譯燒寫輸出文件時(shí)使用的鏈接腳本文件（*.ld）對(duì)ROM_BASE 的定義。
 
 2、重新編譯工程，使用elf2bin工具產(chǎn)生BIN文件；
 
 3、運(yùn)行Flash Programmer，按照實(shí)際情況配置調(diào)試設(shè)備：
    Setting -> configure... 

 4、點(diǎn)擊Open 菜單，打開配置文件（*.cfg），給出燒寫目標(biāo)文件；

> Project directory default: EmbestIDE\Examples\Samsung\S3CEB2410
  If copy to another directory to run, please modify Project ->Settings:
  Linker >Add Library searching Path category >Library Searching Directories:
  	..\..\..\..\Build\xgcc-arm-elf\arm-elf\lib 
  	..\..\..\..\Build\xgcc-arm-elf\lib\gcc-lib\arm-elf\3.0.2
  Change setting as (assume that Embest IDE installtion is C:\):
  	C:\EmbestIDE\Build\xgcc-arm-elf\arm-elf\lib
  	C:\EmbestIDE\Build\xgcc-arm-elf\lib\gcc-lib\arm-elf\3.0.2

> Download the project into RAM to debug, modify Project ->Settings:
      Assembler >General category >Predefines: set as
                
     Linker >General category >Linker script file: set as
               ..\common\ram_ice.ld
    	 
> Program the iamge into Flash to run:
  I. modify Project ->Settings:
	i) run program in Flash space:
	Assembler >General category >Predefines: set as 
		(without any symbol defined)
    Linker >General category >Linker script file: set as
    	..\common\flash.ld
    	
	ii) copy the program from Flash space to RAM to run:
    Project >Settings ->Assembler >General category >Predefines: set as
	        EXEC_FROM_RAM=1
    Linker >General category >Linker script file: set as
    	..\common\ram_ice.ld
    	
  Note: If want to change the image store address instead of 0x0, 
         please modify RAM_BASE defined consist in the linker script file (*.ld)
          before step II.

 II. Rebuild the project and click Tools ->Elf2Bin, 
      generate the Bin format file in directory DEBUG\

 III. Run Embest Falsh Programmer for ARM, then select the configuration file(*.cfg),
       and add the Bin file to program.
