这不是老版本手册,这是H616的手册,SPI驱动是在H616上实现的

这个寄存器是控制SPI时钟的,在新版IP中已经不推荐这样使用,但是这里为了方便还是这样设置

有旧版本的手册吗?另外新版本中应该如何控制SPI时钟呢?
from syterkit.
新版本需要控制父时钟并设置分频,通过CCU控制输入时钟而不是使用SPI硬件,这样可以获得更灵活的频率,但是需要实现完整的clk框架,目前SyterKit使用的是简易框架没有实现

OK,感谢大佬(最后想问一下有旧版本的文档吗
from syterkit.
我可以理解为两块芯片使用的是同一个SPI控制器,所以D1S的配置和使用的方式也可以参照H616嘛
from syterkit.
不是一个控制器,有部分升级,只是在boot阶段需求较少这样用没问题
from syterkit.
那框架中sys-spi只适用于boot。如果要用来驱动外设的话,驱动代码是不完整的嘛。
from syterkit.
是的,使用SPI_CCR的时钟分频非常粗糙,只有几个固定频点可以用,对于部分特殊需求的设备不适用

好的,那我再自己RTFM研究一下,如果后续还是不能驱动ST7789再来请教大佬
