11、移植ColorBar程序,将main.c文件修改为如下形式(别忘了在main.c文件中添加#include “gui.h”的预处理命令):
void DemoShowColorBar(void);
int main(void)
{
SystemInit();
delay_init(72); //延时初始化
NVIC_Configuration();
uart_init(9600);
LED_Init();
KEY_Init();
// LCD_Init();
GUI_Init();
GUI_SetBkColor(GUI_BLACK);
GUI_SetColor(GUI_WHITE);
GUI_Clear();
GUI_SetFont(&GUI_Font24_ASCII);
GUI_DispStringHCenterAt("COLOR_ShowColorBar - Sample", 160, 5);
DemoShowColorBar();
while(1)
{
delay_ms(400);
LED0 = !LED0;
}
}
void DemoShowColorBar(void)
{
int x0 = 60, y0 = 40, yStep = 15, i;
int xsize = LCD_GetDevCap(LCD_DEVCAP_XSIZE) - x0;
GUI_SetFont(&GUI_Font8x16);
#if (LCD_FIXEDPALETTE)
y0 = 66;
yStep = 13;
GUI_DispStringAt("Fixed palette: ", 0, 40);
GUI_DispDecMin(LCD_FIXEDPALETTE);
#endif
GUI_DispStringAt("Red", 0, y0 + yStep);
GUI_DispStringAt("Green", 0, y0 + 3 * yStep);
GUI_DispStringAt("Blue", 0, y0 + 5 * yStep);
GUI_DispStringAt("Grey", 0, y0 + 6 * yStep);
GUI_DispStringAt("Yellow", 0, y0 + 8 * yStep);
GUI_DispStringAt("Cyan", 0, y0 + 10 * yStep);
GUI_DispStringAt("Magenta", 0, y0 + 12 * yStep);
for (i = 0; i < xsize; i++) {
U16 cs = (255 * (U32)i) / xsize;
U16 x = x0 + i;;
/* Red */
GUI_SetColor(cs);
GUI_DrawVLine(x, y0 , y0 + yStep - 1);
GUI_SetColor(0xff + (255 - cs) * 0x10100L);
GUI_DrawVLine(x, y0 + yStep, y0 + 2 * yStep - 1);
/* Green */
GUI_SetColor(cs<<8);
GUI_DrawVLine(x, y0 + 2 * yStep, y0 + 3 * yStep - 1);
GUI_SetColor(0xff00 + (255 - cs) * 0x10001L);
GUI_DrawVLine(x, y0 + 3 * yStep, y0 + 4 * yStep - 1);
/* Blue */
GUI_SetColor(cs * 0x10000L);
GUI_DrawVLine(x, y0 + 4 * yStep, y0 + 5 * yStep - 1);
GUI_SetColor(0xff0000 + (255 - cs) * 0x101L);
GUI_DrawVLine(x, y0 + 5 * yStep, y0 + 6 * yStep - 1);
/* Gray */
GUI_SetColor((U32)cs * 0x10101L);
GUI_DrawVLine(x, y0 + 6 * yStep, y0 + 7 * yStep - 1);
/* Yellow */
GUI_SetColor(cs * 0x101);
GUI_DrawVLine(x, y0 + 7 * yStep, y0 + 8 * yStep - 1);
GUI_SetColor(0xffff + (255 - cs) * 0x10000L);
GUI_DrawVLine(x, y0 + 8 * yStep, y0 + 9 * yStep - 1);
/* Cyan */
GUI_SetColor(cs * 0x10100L);
GUI_DrawVLine(x, y0 + 9 * yStep, y0 + 10 * yStep - 1);
GUI_SetColor(0xffff00 + (255 - cs) * 0x1L);
GUI_DrawVLine(x, y0 + 10 * yStep, y0 + 11 * yStep - 1);
/* Magenta */
GUI_SetColor(cs * 0x10001);
GUI_DrawVLine(x, y0 + 11 * yStep, y0 + 12 * yStep - 1);
GUI_SetColor(0xff00ff + (255 - cs) * 0x100L);
GUI_DrawVLine(x, y0 + 12 * yStep, y0 + 13 * yStep - 1);
}
}
12、下载到开发板运行如下图所示:
