60M的串口屏问题？
调过的，能不能贴一个原理图看看，60那边接的是哪几个pin?
串口屏搞定了，改了一些地方，这里就不贴出是怎么搞的了，改的地方还是有蛮多地方的，有需求可以再发帖吧。

兄弟分享分享下，偶的60m现在同样白屏啊！但是示波器有波形输出哦
你是所有的信号线都有输出吗?
能否给分参考代码?谢谢了！
A0没有输出，配成gpio也能拉高拉低。其它口信号都基本正常。
你是60M的话，你看看你现在A0接的是哪个口子，对的话应该是GPIO36

这是LCD的时序部分，不太好贴代码出来。你配了哪些地方?有什么现象?所有的数据和控制信号都量过没?
主要是硬件上面的。
信号方面所有的脚都正常了。GC9101的IC，FAE说他们抓取的SDA8位要不全是0要不全是1

不是啊，我们的是GPIO39
GPIO39是不是串口的A0 那是并口的A0， 你飞线试下

以上是一些主要函数，可以开机点亮，看到系统图片，
但是在 LCD_BlockWrite_ST7789S（）刷单色LCD_ClearAll_ST7789S（0xF800)不起作用，
另外读ID不起作用 ST7789S= 0x00,0x00,0x00,0x00
请教下大神该如何处理，谢谢了
串口屏 读ID返回都是00 00 00 啊 ，，怎么弄
学习。
marking.....
学习，就是代码看得不舒服，管理员要开发个可以贴代码得。
