最近在驱动OV7725时代码上遇到了一个问题
- typedef struct
- {
- uint8_t QVGA_VGA; /*0:QVGA 1:VGA*/
- /*QVGA:sx + width <=320, sy + heigth <=240*/
- /*VGA:sx + width <=320 或 240, sy + heigth <=320 或 240*/
- uint16_t cam_sx; /*摄像头窗口X起始位置*/
- uint16_t cam_sy; /*摄像头窗口Y起始位置*/
- uint16_t cam_width;/*图像分辨率，宽*/
- uint16_t cam_height;/*图像分辨率，高*/
- uint16_t lcd_sx;/*图像显示在液晶屏的X起始位置*/
- uint16_t lcd_sy;/*图像显示在液晶屏的Y起始位置*/
- uint8_t lcd_scan;/*液晶屏的扫描模式（0-7）*/
- uint8_t light_mode;/*光照模式，参考范围[0~5]*/
- int8_t saturation;/*饱和度，参考范围[-4~+4]*/
- int8_t brightness;/*光照度，参考范围[-4~+4]*/
- int8_t contrast;/*对比度，参考范围[-4~+4]*/
- uint8_t effect;/*特殊模式，参考范围[0~6]*/
- }OV7725_MODE_PARAM;
我该如何对其里面的值赋值
- OV7725_MODE_PARAM cam_mode =
- {
- .QVGA_VGA = 0,
- .cam_sx = 0,
- .cam_sy = 0,
- .cam_width = 320,
- .cam_height = 240,
- .lcd_sx = 0,
- .lcd_sy = 0,
- .lcd_scan = 3,
- .light_mode = 0,
- .saturation = 0,
- .brightness = 0,
- .contrast = 0,
- .effect = 0,
- };
我参考STM32的例程对其赋值，但是系统报错#29 expected an expression，想问下大家有什么解决方法？
