STemWin在STM32上移植驱动12864屏（ST7920）求助！

modu8888 提问时间：2017-10-20 08:46 /

   我是用串口驱动12864点阵屏（ST7920）的，现在已经用调用字库设计了菜单。后来想把节目做的绚烂一些，所以想到在STM32F105上移植STemWin。

   参考网上的一些攻略，已经把打点、画线等底层函数写好，且修改了有关文件。但调用STemWin的函数，就是不理会呢！
/******************下面是打点和读点函数，测试可用**********************/
   void LCM_PutPixel(uint16_t x, uint16_t y, uint8_t color)
{
uint16_t newHalfWordValue;
uint8_t xHalfWordPlace,xHolfWordOfBit;

if((x>=128)||(y>=64))
return;

xHalfWordPlace = x / 16;  //

if(y >= 32)
{
y = y - 32;
xHalfWordPlace = xHalfWordPlace + 8;
}

newHalfWordValue = localcachebuf[y][xHalfWordPlace];
xHolfWordOfBit = x % 0x10;
if(0 == color)
{
newHalfWordValue &= clearBitTable[xHolfWordOfBit];
}
else
{
newHalfWordValue |= setBitTable[xHolfWordOfBit];
}

localcachebuf[y][xHalfWordPlace]=newHalfWordValue;
}

bool LCM_GetPixel(uint16_t x, uint16_t y)
{
uint16_t oldHalfWordValue;
  uint8_t xHalfWordPlace,xHolfWordOfBit;

  xHalfWordPlace = x / HALF_WORD_OF_ROWS;

  if(y >= 32)
{
y = y - 32;
xHalfWordPlace = xHalfWordPlace + 8;
  }

  oldHalfWordValue = localcachebuf[y][xHalfWordPlace];
xHolfWordOfBit = x % 0x10;
oldHalfWordValue=oldHalfWordValue & setBitTable[xHolfWordOfBit];
  return oldHalfWordValue << xHolfWordOfBit;
}

/*******************刷屏函数  在RAM中开辟1024字节存放显示内容，在级别较低的任务中用SPI写************************/
void LCM_Refresh()
{
uint16_t x,y,i;
for(y=0;y<32;y++)
{
LCM_WriteCommand(0x80+y);
Delay_CLK(120);
LCM_WriteCommand(0x80);
Delay_CLK(120);
for(x=0;x<8;x++)
{
i=localcachebuf[y][x];
LCM_WriteData(i>>8);
Delay_CLK(120);
LCM_WriteData((uint8_t)i);
Delay_CLK(120);
}
}

for(y=0;y<32;y++)
{
LCM_WriteCommand(0x80+y);
Delay_CLK(120);
LCM_WriteCommand(0x88);
Delay_CLK(120);
for(x=0;x<8;x++)
{
i=localcachebuf[y][x+8];
LCM_WriteData(i>>8);
Delay_CLK(120);
LCM_WriteData((uint8_t)i);
Delay_CLK(120);
}
}
LCM_WriteCommand(0x36);
}

在GUI.c中修改
#define GUI_NUMBYTES  (10*1024)

修改GUIDRV_Template.c中读点函数、写点函数是自己定义的：
static void _SetPixelIndex(GUI_DEVICE * pDevice, int x, int y, int PixelIndex) {
      LCM_PutPixel(x,y,PixelIndex);
}

static unsigned int _GetPixelIndex(GUI_DEVICE * pDevice, int x, int y) {
  unsigned int PixelIndex;
//
// Convert logical into physical coordinates (Dep. on LCDConf.h)
//
#if (LCD_MIRROR_X == 1) || (LCD_MIRROR_Y == 1) || (LCD_SWAP_XY == 1)
   int xPhys, yPhys;

   xPhys = LOG2PHYS_X(x, y);
   yPhys = LOG2PHYS_Y(x, y);
#else
   #define xPhys x
   #define yPhys y
#endif
GUI_USE_PARA(pDevice);
GUI_USE_PARA(x);
GUI_USE_PARA(y);
{
   PixelIndex = LCM_GetPixel(x,y);
}
#if (LCD_MIRROR_X == 0) && (LCD_MIRROR_Y == 0) && (LCD_SWAP_XY == 0)
   #undef xPhys
   #undef yPhys
#endif
  return PixelIndex;
}

在LCDConf_FlexColor_Template.c中修改显示屏的尺寸
// Physical display size
//
#define XSIZE_PHYS  128 // To be adapted to x-screen size
#define YSIZE_PHYS  64 // To be adapted to y-screen size
#define VXSIZE_PHYS 128
#define VYSIZE_PHYS 64
色彩转换也改了

void LCD_X_Config(void) {
  //
  // Set display driver and color conversion
  //
  GUI_DEVICE_CreateAndLink(GUIDRV_FLEXCOLOR, GUICC_1, 0, 0);
  //
  // Display driver configuration, required for Lin-driver
  //
  LCD_SetSizeEx (0, XSIZE_PHYS , YSIZE_PHYS);
  LCD_SetVSizeEx(0, VXSIZE_PHYS, VYSIZE_PHYS);
}
