RA8870 STemWin5.26 f405

sirbai008

调试ra8870一星期了，调试时一直卡在emWin_LCD_Init里LCD_FillRect里的_FillRect，在执行BTE使能命令(0x50-0x80)时进入hardfalut(此时屏幕白屏)
，用自带的驱动可显示窗口文字，fsmc配置无数次无果

怎么不用我们开发的在emWin下的通用驱动方案，很好用。官网的这种驱动一直没有用过。

他说的有些小问题，也嫌麻烦吧

sirbai008

PortAPI.pfWrite16_A0  =LcdWriteReg;
        PortAPI.pfWrite16_A1  =  LcdWriteData;
    PortAPI.pfWriteM16_A1 = LcdWriteDataMultiple;
    PortAPI.pfReadM16_A1  = LcdReadDataMultiple;
这块函数补全就好了
