LCD驱动代码解疑

kingdavid

bsp_LCD.h文件里

#define HBP  24               
#define VBP   3

#define HSW   6
#define VSW   1

#define HFP  10
#define VFP   4

以上代码怎么和屏资料对应？

bsp_LCD.c文件里

/* LTDC Configuration *********************************************************/
/* Polarity configuration */
/* Initialize the horizontal synchronization polarity as active low */
LTDC_InitStruct.LTDC_HSPolarity = LTDC_HSPolarity_AL;
/* Initialize the vertical synchronization polarity as active low */
LTDC_InitStruct.LTDC_VSPolarity = LTDC_VSPolarity_AL;
/* Initialize the data enable polarity as active low */
LTDC_InitStruct.LTDC_DEPolarity = LTDC_DEPolarity_AL;
/* Initialize the pixel clock polarity as input pixel clock */
LTDC_InitStruct.LTDC_PCPolarity = LTDC_PCPolarity_IPC;


屏驱动信号DE极性和资料不一致，是不是资料描述不对？

按资料来做不正确，改成相反的就对了,
估计资料跟实际产品有点差异

驱动头文件里的几个参数呢？应该怎么对应时序参数？
