使用5寸屏幕初始化时遇到的问题

sunboy

我想问一下在STM32中，带SSD1963的 LCD屏幕初始化中的HT，HPS，HPW.VT.VPS,VPW,FPS的这些值根据什么公式得到的？

LCD_WR_REG(0x00B4); //HSYNC

LCD_WR_Data((HT>>8)&0X00FF);  //Set HT

LCD_WR_Data(HT&0X00FF);

LCD_WR_Data((HPS>>8)&0X00FF);  //Set HPS

LCD_WR_Data(HPS&0X00FF);

LCD_WR_Data(HPW);   //Set HPW

LCD_WR_Data((LPS>>8)&0X00FF);  //Set HPS

LCD_WR_Data(LPS&0X00FF);

LCD_WR_Data(0x0000);

LCD_WR_REG(0x00B6); //VSYNC

LCD_WR_Data((VT>>8)&0X00FF);   //Set VT

LCD_WR_Data(VT&0X00FF);

LCD_WR_Data((VPS>>8)&0X00FF);  //Set VPS

LCD_WR_Data(VPS&0X00FF);

LCD_WR_Data(VPW);   //Set VPW

LCD_WR_Data((FPS>>8)&0X00FF);  //Set FPS

LCD_WR_Data(FPS&0X00FF);
