求助，ThreadX+GUIX屏幕是NT35510显示驱动移植问题

ning0720

大家好，我自己的开发板使用的NT35510屏幕芯片，参考咱V5的GUIX移植demo，我自己重新移植了LCD驱动，现在就简单的替换了驱动函数中的内容（stm32f4_565rgb_buffer_toggle（）），屏幕可以点亮，但是不显示内容。求助大佬们帮忙看下，我的这个屏幕驱动函数写的对不对，非常感谢，并附上源代码。

我这里是做了个展开绘制。

你直接调用你的这个函数lcd_color_fill试试

非常感谢汉哥，我用了lcd_color_fill这个函数，确实有点反应。这个lcd_color_fill函数，好像是传入一个区域+颜色，从而实现显示。我得了解GUIX的显示原理，才能写出移植代码，头大。

不用了解机制，注意你调用你的这个函数lcd_color_fill，注意它的坐标大小和位置就行。应该就是参数传递问题，你整准点。

大家好，STM32F407ZG+NT35510+GT9147，屏幕显示驱动和触摸屏驱动已经移植完成，但是有一个小bug，按下button页面就乱了，按下button之外的地方，页面就恢复正常了，这是咋回事？是触摸屏驱动没写好吗？求大佬们指点，万分感谢！

非常感谢，现在重新传了参数，已经能正常显示了。但是触摸屏又有点问题，我已经在帖子最下方传了新的问题和工程，汉哥有空的时，帮忙指点一下，再次感谢

现在的触摸跟我分享的那种函数一样吧，没看到你的接口实现函数。

对，一样，驱动函数就用的你写好的TOUCH_PutKey，在touch.c的最下面，gtxxx.c中gt9xxx_scan扫描函数调用了TOUCH_PutKey，下面是两个截图，非常感谢

那没问题了。
