使用的是荔枝派Nano 跨界核心板,板子的tp芯片是ns2009, 之后我下载了(zero-4.13.y分支: git clone https://github.com/Lichee-Pi/linux.git -b zero-4.13.y, 将zero板子代码中的ns2009.c拿出来, 添加到nano内核中并且使能, 编译都正常
suniv-f1c100s-licheepi-nano.dts 如下:
&i2c0 {
status = "okay";
ns2009: ns2009@48 {
compatible = "nsiway,ns2009";
reg = <0x48>;
};
};开机log如下:

我仔细看过置顶的帖子"荔枝派nano(f1c100s)的SPI-Flash系统编译创建全过程"这个帖子, 是2月份的帖子,里面没有提到上拉电阻的问题,哪位能给我个准确的信息,nano板子到底要不要接上拉电阻,我是偏软件的,焊工不行,担心板子搞坏了,板子太小了

我的板子好像跟上个帖子不太一样, 我的新一点? 尤其是触控芯片那里
离线
感谢!!!! 我试试自己弄吧
E11(E12) 飞线出来至 电阻一端, 之后电阻另一端接板子上的地, 对吧??
这个错误一般就是没有接上拉电阻， 3.3k估计也没有问题，请个硬哥帮忙焊一下。

谢谢,可以了,就是加上拉电阻!

啊,这样, 那应该用哪个? 还是自己想办法去改?
那个 ns2009 的驱动没有用中断, 而是驱动不停轮询, 机制不太好.
离线
好的,谢谢提醒!
没事, 可以用, 只是有点浪费CPU而已.
你可以接一个中断脚, 然后驱动实现中断优化一下, 当然,不改也是一样的用.
