1. Color指令
a) CMD_FGCOLOR -设定前景颜色
| +0 | CMD_FGCOLOR(0xffffff0a) |
| +4 | Color |
Color是24bit RGB的数值。例如设置前景色为红色：
ftWrDispCmd(CMD_FGCOLOR);
ftWrDispCmd(0xff0000);
该命令能作用在CMD_BUTTON、CMD_KEYS、CMD_SCROLLBAR、CMD_TOGGLE、CMD_SLIDER等（应用于前景能移动的控件上）
b) CMD_BGCOLOR -设定背景颜色
| +0 | CMD_BGCOLOR(0xffffff09) |
| +4 | Color |
同前景色的方式一样
ftWrDispCmd(CMD_BGCOLOR);
ftWrDispCmd(0xff0000);
该命令能作用在CMD_SCROLLBAR、CMD_GAUGE、CMD_PROCESS、CMD_SLIDER等控件(应用于背景不能移动的控件上)
c) CMD_GRADCOLOR -设定3D按键上强调显示的颜色
| +0 | CMD_GRADCOLOR(0xffffff34) |
| +4 | Color |
同前景色
ftWrDispCmd(CMD_GRADCOLOR);
ftWrDispCmd(0xff0000);
该命令只能作用在CMD_BUTTON、CMD_KEYS上，改变的是按键上的渐变色。

2. Button
CMD_BUTTON –绘制一个按钮
| +0 | CMD_BUTTON(0xffffff0d) |
| +4 | X |
| +6 | Y |
| +8 | W |
| +10 | H |
| +12 | Font |
| +14 | Option |
| +16 |
String |
| … | … |
| +n | 0 |
用宏定义写入CMD_BUTTON:
#define ftCoCmdButton(x, y, w, h, font, options, s) \
{\
uint16_t len = strlen((char *)s) + 1; \
ftWrDispCmd(CMD_BUTTON);\
ftWrDispCmd(((uint32_t)(y) << 16) | ((x) & 0xffff));\
ftWrDispCmd(((uint32_t)(h) << 16) | (w));\
ftWrDispCmd(((uint32_t)(options) << 16) | (font));\
ftWrDispBuf(s, len); \
}
参数x, y, w, h分别表示按钮的左顶点x, y坐标和长宽。font是按钮上显示字符串的handle值，option有效值为0(3D 效果)或者OPT_FLAT(扁平效果)。最后是按钮上的字符串，以0为结束。
ftCoCmdButton((LCD_WIDTH / 2 - 150), (LCD_HEIGHT / 2 - 110), 140, 100, 31, 0, "Press!");
ftCoCmdButton((LCD_WIDTH / 2 + 10), (LCD_HEIGHT / 2 - 110), 140, 100, 31, OPT_FLAT, "Press!");
ftCoCmdButton((LCD_WIDTH / 2 - 100), (LCD_HEIGHT / 2 + 10), 50, 25, 26, 0, "One");
ftCoCmdButton((LCD_WIDTH / 2 - 100), (LCD_HEIGHT / 2 + 40), 50, 25, 26, 0, "Two");
ftCoCmdButton((LCD_WIDTH / 2 - 100), (LCD_HEIGHT / 2 + 70), 50, 25, 26, 0, "Three");

ftWrDispCmd(CMD_FGCOLOR);
ftWrDispCmd(0xb97300);
ftCoCmdButton((LCD_WIDTH / 2 + 50), (LCD_HEIGHT / 2 + 40), 50, 25, 26, 0, "Two");
ftWrDispCmd(CMD_FGCOLOR);
ftWrDispCmd(0xb90007);

ftWrDispCmd(((uint32_t)(options) << 16) | ((r) & 0xffff));\
ftWrDispCmd(((uint32_t)(m) << 16) | ((h) & 0xffff));\
ftWrDispCmd(((uint32_t)(ms) << 16) | ((s) & 0xffff));\
}
