您好! 请问GUIDER在生成C文件时,能把lv_meter_scale_t变量定义与lv_meter_indicator_t变量定义一样放入gui_guider.h文件中吗?这样使用lv_meter_scale_t变量时就方便很多。否则象现在的状态就是我每用GUIDER生成一次C文件,就要手动修改lv_meter_scale_t变量为全局变量。
现有meter控件的刻度变量lv_meter_scale_t为局部变量,仪表程序无法适应用户变量单位变化。如果改为全局变量,就能动态改变仪表的刻度。譬如仪表的刻度单位从KPa变为Psi,或从摄氏度改为华氏度等。谢谢!

在使用 LV_METER_SET_SCALE_RANGE 函数时,需要先调用 LV_METER_GET_VALUE 函数获取当前刻度范围,然后修改参数并调用 LV_METER_SET_SCALE_RANGE 函数设置新的刻度范围。最后,调用 LV_METER_REFRESH 函数刷新仪表显示。 函数的返回值是布尔值,表示设置是否成功。如果设置成功,返回 true;如果设置失败,返回 false。在...
