LV_METER_SET_SCALE_RANGE 函数主要有两个参数,分别是刻度起点和刻度终点。这两个参数决定了仪表的刻度范围,也直接影响到仪表的测量结果。在使用 LV_METER_SET_SCALE_RANGE 函数时,需要确保这两个参数的准确性,以保证仪表的测量精度。 使用LV_METER_SET_SCALE_RANGE 函数的方法非常简单,首先需要调用该函数,然后传...
lv_meter_set_scale_range(meter, 0, 100); lv_obj_set_pos(meter, 10, 10); lv_obj_set_size(meter, 200, 100); } #endif ``` 运行上述代码,将创建一个仪表控件,并设置其刻度范围为0 到 100。 III.函数应用场景 A.刻度范围设置的重要性 在实际应用中,仪表刻度范围的选择非常关键。合适的刻度范围...

lv_gauge_set_scale这个函数比较复杂,在V7版本中API文档说明如下: voidlv_gauge_set_scale(lv_obj_t*gauge, uint16_tangle, uint8_tline_cnt, uint8_tlabel_cnt) Set the scale settings of a gauge Parameters •gauge: pointer to a gauge object •angle: angle of the scale (0..360) •line...
Would it be normal if these functions (at least the ones with lv_rand) move in the ms range on a STM32F7xx? screen_meter_1_scale_1_ndimg_0 = lv_meter_add_needle_line(ui.screen_meter_1, screen_meter_1_scale_1, 4, lv_color_make(0xff, 0x00, 0x00), -30); while (1) { ...
首先,我们需要了解lv_meter_set_scale_range函数的基本用法。该函数是LabVIEW中的一个内置函数,用于设置仪表控件的刻度范围。它的基本语法如下: 【lv_meter_set_scale_range】(Meter control, range minimum, range maximum) 其中,【Meter control】表示需要设置刻度范围的仪表控件,【range minimum】表示刻度范围的最小...
1. What is lv_meter_set_scale_range? The lv_meter_set_scale_range function is a part of the LittlevGL library, which is an open-source graphics library for embedded systems. The function is specifically designed for managing the scale rangeof meter objects. By defining the minimum and maxim...
