感觉15，16帧的样子

我觉得显示不流畅，显示驱动有问题。
初步反编译看了下，没有使用双缓冲。
就是没源码，另外调试也不方便，想改进下显示驱动。楼主知道怎么调试吗？

miyoo这么大张旗鼓的，不怕被任天堂告侵权赔偿么？

图里那3个焊点是uart接口吗？哪个是tx rxhttps://whycan.cn/files/members/1770/none.png

请问大神, 这个 miyoo链接 怎么玩?

司徒删除了所有源码，在github搜索miyoo还能收到很多其他人fork司徒的源码

都被我叉过来了:

ok
it is hard to explain something
first
not all of screen has TE pinout
ex: v2 bittboy
second
the TE pin is open on PCB for some bittboys
so, for v1, you need short it manually
and
even though all of hardware are ready
the trigger rate is only 40hz in f1c500s
I mean TE is output around 60hz
but f1c500s only get 40hz in kernel driver
so, many issues
I dont know how to say that
but
if you fix your hardware, maybe, you can check kernel whether it is somgthing I overlooked
any question ?

People says:
-------------
kernel gets 40Hz instead of 60Hz because it is too slow to process it or the signal got lost in hw, for example by lack of filtering or filtering too much?
i have bittboy v2.5

Steward says:
-------------
we use oscilloscope to double check and hw can ouput 60hz
in kernel, I just accumulate and print it
and the result is 40hz
even though boost priority for innterrupt
the result is same as without boos priority
we also check with some engineers who developed f1c500s
they havent checked this when produce this ic
I mean no any verification with interrupt speed
so, I dont know whats the root cause
maybe, kernel or IC
if you know this, please tell me
thanks
