The following derivatives are currently supported: SED1352 SED1354 SED1356 (With/Without BitBlt engine support) SED1374 SED1375 SED13806 Other Epson LCD controllers are very similar and could be covered by this driver as well, but have not been tested. ---------------------------------------------------------------------- ---------------------------LIST OF CONFIG SWITCHES-------------------- The following is a list of additional configuration switches for this driver. These switches might not be listed in the manual, because the manual mainly covers the general config switches which are supported by all drivers. ---------------------------------------------------------------------- define ----------------------Explanation------------------------------ LCD_SWAP_BYTE_ORDER Activate if high low bytes are swapped Default: 0 LCD_WRITE_MEM32(Off,Data32) This macro accelerates display access if defined by allowing the CPU to write 32 bits at a time to the controller. (For 32 bits CPUs only and only if the BUS interface unit can automatically convert this to 2 16 bit accesses LCD_OPTIMIZE Controls the use of optimized routines. If 1, several (speed) optimizations are used. Default: ON (1) LCD_USE_BITBLT This switch controls the use of optimized routines with SED1356 bitblt engine. If 1, the optimized routines with bitblt access are used. The default value depends of LCD_BITSPERPIXEL: (4 ) -> 0, (8,15) -> 1 LCD_ENABLE_REG_ACCESS() LCD_ENABLE_MEM_ACCESS() In most systems (and with most LCD-controllers) registers / memory can be accessed at different addresses. However, in some systems, it could be necessary to exec code in order to be able to access the registers or memory. This code should then be placed in these macros (rather than the actual access macros, which would be slowed down) LCD_DATAADR define adress if video memory can be treated like regular memory (will speed up driver) ---------------------------------------------------------------------- Known problems or limitations with current version ---------------------------------------------------------------------- none ---------------------------------------------------------------------- Open issues ---------------------------------------------------------------------- None ---------------------------END-OF-HEADER------------------------------ */ #include <stddef.h> /* needed for definition of NULL */ #include "LCD_Private.H" /* private modul definitions & config */ #include "GUI_Private.H" #include "GUIDebug.h" #include "LCD_0.h" /* Defines for first display */ // extern U8 LCD_Buffer [LCD_XSIZE*LCD_YSIZE]; extern U8 LCD_Buffer []; // 对 Video RAM 区的读写操作. #define LCD_READ_MEM(Off) LCD_Buffer[Off] #define LCD_WRITE_MEM(Off,data) LCD_Buffer[Off]=data #define LCD_READ_REG(Off) 0 #define LCD_WRITE_REG(Off,data) #if (LCD_CONTROLLER/100 == 13) && (LCD_CONTROLLER/10 != 133) \ && (!defined(WIN32) | defined(LCD_SIMCONTROLLER)) /* ********************************************************* * * * Compiler specific settings * * * ********************************************************* */ #ifdef WIN32 /* Avoid warnings in MS-compiler */ #pragma warning(disable : 4244) // warning C4244: '=' : conversion from 'long ' to 'unsigned char ', possible loss of data #pragma warning(disable : 4761) // warning C4761: integral size mismatch in argument; conversion supplied #endif /* ********************************************************* * * Controller renumbering * ********************************************************* EPSON decided to rename all of their controllers.
