EVE-14 Slider Dial Toggle Number
1. Slider(滑块)
CMD_SLIDER –绘制一个滑块
#define ftCoCmdSlider(x, y, w, h, options, val, range)\
{\
ftWrDispCmd(CMD_SLIDER);\
ftWrDispCmd(((uint32_t)(y) << 16) | ((x) & 0xffff));\
ftWrDispCmd(((uint32_t)(h) << 16) | (w));\
ftWrDispCmd(((uint32_t)(val) << 16) | (options));\
ftWrDispCmd(((uint32_t)range));\
}
参数含义与progress相同。
ftCoCmdSlider((PANEL_WIDTH / 2 - 60), (PANEL_HEIGHT / 2 - 30), 120, 12, 0, progress, 10);
ftCoCmdSlider((PANEL_WIDTH / 2 + 120), (PANEL_HEIGHT / 2 - 60), 12, 120, OPT_FLAT, progress, 10);
2. Dial
CMD_DIAL –绘制一个旋转拨号控制
#define ftCoCmdDial(x, y, r, options, val)\
{\
ftWrDispCmd(CMD_SLIDER);\
ftWrDispCmd(((uint32_t)(y) << 16) | ((x) & 0xffff));\
ftWrDispCmd(((uint32_t)(options) << 16) | (r));\
ftWrDispCmd((uint32_t)val);\
}
参数options支持0和OPT_FLAT，val表示拨号盘指针的位置，有效值0-65535，以正下面中间为起始点，360°等分为65535份。
ftCoCmdDial((PANEL_WIDTH / 2 - 100), (PANEL_HEIGHT / 2), 60, 0, dial * 65535 / 360);
ftCoCmdDial((PANEL_WIDTH / 2 + 100), (PANEL_HEIGHT / 2), 60, OPT_FLAT, dial * 65535 / 360);
3. Toggle
CMD_TOGGLE –绘制一个切换开关
#define ftCoCmdToggle(x, y, w, font, options, state, const char *s)\
{\
uint16_t len = strlen((char *)s) + 1; \
ftWrDispCmd(CMD_TOGGLE);\
ftWrDispCmd(((uint32_t)(y) << 16) | ((x) & 0xffff));\
ftWrDispCmd(((uint32_t)(font) << 16) | ((w) & 0xffff));\
ftWrDispCmd(((uint32_t)(state) << 16) | ((options) & 0xffff));\
ftWrDispBuf(s, len);\
}
参数x, y是开关左上角的坐标。options只支持0和OPT_FLAT。state是开关的状态，0为关，65535为开。字符串是用字符值255区隔开关的字符串。
ftWrDispCmd(TAG_MASK(1));
ftWrDispCmd(TAG(2));
if (toggle == 0)
{
ftCoCmdToggle((PANEL_WIDTH / 2 - 20), (PANEL_HEIGHT / 2), 40, 27, 0, 0, "No""\xff""Yes");
}
else
{
ftCoCmdToggle((PANEL_WIDTH / 2 - 20), (PANEL_HEIGHT / 2), 40, 27, 0, 65535, "No""\xff""Yes");
}
4. Number
CMD_NUMBER –绘制一个十进位数字
#define ftCoCmdNumber(x, y, font, options, n)\
{\
ftWrDispCmd(CMD_NUMBER);\
ftWrDispCmd(((uint32_t)(y) << 16) | ((x) & 0xffff));\
ftWrDispCmd(((uint32_t)(options) << 16) | (font));\
ftWrDispCmd(n);\
}
FT80x只能显示十进制数字，FT81x可以通过命令CMD_SETBASE设置成2-36进制显示。参数n是int32或uint32的数据类型。如果是int32类型，options要增加OPT_SIGNED的参数。
ftCoCmdNumber((LCD_WIDTH / 2), (LCD_HEIGHT / 2 - 60), 27, OPT_SIGNED, -2700);
ftCoCmdNumber((LCD_WIDTH / 2), (LCD_HEIGHT / 2), 31, OPT_CENTER, 2700);
