现向大家介绍UCGUI第三个例子：2DGL_DrawScale
VC仿真结果：
(原文件名:2DGL_DrawScale.jpg)
ARM移植效果：
(原文件名:图片 008.jpg)
实验Code:
static void _DrawScale(void) {
int XSize = LCD_GetXSize(); //获取LCD 边界
int YSize = LCD_GetYSize();
int XMid = XSize / 2;
int i;
int r1 = 110;
int r2 = 140;
int rt = 100;
int y = 240;
int step = 15;
int r = (r1 + r2) / 2;
GUI_SetBkColor(GUI_BLACK);
GUI_Clear();
GUI_SetColor(GUI_WHITE);
GUI_SetFont(&GUI_Font24_ASCII); //区24X24字符
GUI_SetTextAlign(GUI_TA_HCENTER); //居中显示
GUI_DispStringAt("DrawScale - Sample", 160, 5);
while (1) {
int c = 0;
GUI_SetColor(GUI_WHITE);
GUI_SetFont(&GUI_Font8x16);
GUI_SetTextAlign(GUI_TA_LEFT);
GUI_Delay(1000);
GUI_DispStringAtCEOL("using", 5, 40);
GUI_DispStringAtCEOL("GUI_AA_DrawArc", 5, 55);
GUI_Delay(1750);
GUI_SetPenSize(r2 - r1);
GUI_SetColor(0x0000AA);
GUI_AA_DrawArc(XMid, y, r, r, 45, 60);
GUI_Delay(1500);
GUI_SetColor(0x00AA00);
GUI_AA_DrawArc(XMid, y, r, r, 60, 90);
GUI_Delay(1500);
GUI_SetPenSize(2);
GUI_SetColor(GUI_WHITE);
GUI_AA_DrawArc(XMid, y, r1, r1, 45, 135);
GUI_Delay(1500);
GUI_AA_DrawArc(XMid, y, r2, r2, 45, 135);
GUI_Delay(2000);
GUI_DispStringAtCEOL("", 5, 55);
GUI_Delay(200);
GUI_DispStringAtCEOL("using", 5, 40);
GUI_DispStringAtCEOL("GUI_AA_DrawLine & GUI_DispCharAt", 5, 55);
GUI_Delay(5000);
for (i = 45; i <= 135; i += step) {
float co = cos(i * 3.1415926 / 180);
float si = sin(i * 3.1415926 / 180);
int x1 = XMid - r1 * co;
int y1 = y - r1 * si;
int x2 = XMid - (r2 - 1) * co;
int y2 = y - (r2 - 1) * si;
int xt = XMid - rt * co;
int yt = y - rt * si;
GUI_SetColor(GUI_WHITE);
GUI_SetPenSize(2);
GUI_AA_DrawLine(x1, y1, x2, y2);
GUI_SetColor(GUI_GREEN);
GUI_SetFont(&GUI_Font8x8);
GUI_DispCharAt('0' + c++, xt - 4, yt - 4);
GUI_Delay(750);
}
GUI_Delay(5250);
GUI_ClearRect(0, 30, 320, 240);
}
