泰山派6寸触摸屏适配笔记

前言

之前在立创开源广场看到了个6寸的触摸屏，感觉这玩意比3.1寸大，又比10寸的便携，搞个小摆件还是不错的。由于自己用的内核是5.10.160+ubuntu22，设备树和驱动直接拷过来编译有错误，特地折腾一下。

设备树修改

修改完设备树刷入内核就可以点屏了

折腾触摸

一开始在dmesg中看到goodix-ts驱动已加载的报错有点纳闷，后来看了一下内核的config，需要取消编译其他goodix的触屏驱动，只留下GT9XX

1

CONFIG_TOUCHSCREEN_GOODIX=n
CONFIG_TOUCHSCREEN_GT1X=n
CONFIG_TOUCHSCREEN_GT9XX=y

修改驱动，swap xy与翻转xy
修改gtp_touch_down函数
gt9xx.c

if (TRUE) {
    if (gtp_x_reverse)
        x = ts->abs_x_max - x;

    if (gtp_y_reverse)
        y = ts->abs_y_max - y;
}

初始化序列修改

记录一下wayland libinput如何调试旋转触摸

安装 libinput-tools

1
apt install libinput-tools

查看输入debug信息

1
libinput debug-events

旋转触摸输入
默认

1
echo 'ENV{LIBINPUT_CALIBRATION_MATRIX}="1 0 0 0 1 0"' > /etc/udev/rules.d/libinput.rules

y轴反向

1
echo 'ENV{LIBINPUT_CALIBRATION_MATRIX}="1 0 0 0 -1 1"' > /etc/udev/rules.d/libinput.rules

x轴反向

1
echo 'ENV{LIBINPUT_CALIBRATION_MATRIX}="-1 0 1 0 1 0"' > /etc/udev/rules.d/libinput.rules

x、y反向

1
echo 'ENV{LIBINPUT_CALIBRATION_MATRIX}="-1 0 1 0 -1 1"' > /etc/udev/rules.d/libinput.rules
