要在STM32的LCD屏上显示进度条,可以使用以下代码实现:
```c
// 定义进度条的位置和尺寸
#define PROGRESS_BAR_X 50
#define PROGRESS_BAR_Y 100
#define PROGRESS_BAR_WIDTH 200
#define PROGRESS_BAR_HEIGHT 20
// 显示进度条函数
void displayProgressBar(uint8_t progress) {
// 计算进度条的长度
uint16_t progressBarLength = (progress * PROGRESS_BAR_WIDTH) / 100;
// 绘制进度条的背景
lcd_interface.lcd_fillRect(PROGRESS_BAR_X, PROGRESS_BAR_Y, PROGRESS_BAR_WIDTH, PROGRESS_BAR_HEIGHT, LCD_COLOR_GRAY);
// 绘制进度条的前景
lcd_interface.lcd_fillRect(PROGRESS_BAR_X, PROGRESS_BAR_Y, progressBarLength, PROGRESS_BAR_HEIGHT, LCD_COLOR_GREEN);
}
```
在上述代码中,我们首先定义了进度条的位置和尺寸。然后,通过`displayProgressBar`函数来显示进度条。该函数接受一个表示进度的参数`progress`,范围为0到100。根据进度参数,计算出进度条的长度,并使用LCD屏的绘制函数来绘制进度条的背景和前景。
你可以根据自己的需求来调整进度条的位置和颜色。
