45块顺丰包邮买到的10.1寸保资LCD价签F1C200S 值不值
https://whycan.com/t_11396.html#p100972

这楼有大佬分享了。

大佬们还有没有什么好玩的。
现在我搞成cpu解码1280*800的jpg。cpu占用有点高。
现在程序是20张图片循环播放。不过cpu占用在98%。再加按键和网页控制参数感觉会爆啊。

@DDER

感谢成功读取到KEY。

电容都好脆了。。。不小心怼碎了。。。

@DDER
原来是79的LRADC0。谢谢告知！

拆开了。附上镜面侧面照片。和拆开后的正面照片。没用吹风机。拆开后发现这胶水很硬，吹了也没软。
我直接贴着玻璃和外壳拿工具戳下去点只要戳下去1mm左右，然后把玻璃翘起来，然后拿卡片塞进去划开的。

屏幕好难拆。
有没有大佬分享一下。
背光电路的R74 和 R75在后壳的哪个位置啊。还有F1C200S芯片位置。准备上i2c设备，然后试试编译i2c-dev试试。
准备直接热熔大法从后壳精准开孔。。

如果可以的话麻烦分享一下！感谢！

@litedoufu
换数据线，确保数据线是支持传输数据的。
插上电脑有叮咚声音的就是对的。
剩下的可能就是ADB版本问题了。

大佬，我业余玩家，搞了个电子相册循环播放照片。准备改成后台可以修改照片切换时间和上传图片。关于你程序中html修改配置的方式，可以简单说说用什么做后台吗。nodejs吗。flask？可以推荐推荐吗，感谢！

吐血……谢谢大佬。只能拿来纯玩了……

dts里显示有i2c设备。

模块引脚    F1C200S
VCC    3.3V
GND    GND
SDA    TWI0_SDA/PD0
SCL    TWI0_SCK/PD12

网上也搜到一个f1c200s使用i2c设备的链接。我是半吊子，手上也没有多的i2c设备。

待确认的问题
如何修改屏幕背光？
45块买到的10.1寸保资LCD价签F1C200S (二)
https://whycan.com/t_11726.html
这里有人弄好调背光了。要把R74 和 R75 短路。

如何修系统时区？
下这个文件Shanghai.txt
创建目录
adb shell
mkdir -p /usr/share/zoneinfo/Asia

上传时区文件
adb push Shanghai.txt /usr/share/zoneinfo/Asia/Shanghai

创建符号链接
adb shell
ln -sf /usr/share/zoneinfo/Asia/Shanghai /etc/localtime
创建或更新/etc/timezone文件
echo "Asia/Shanghai" > /etc/timezone

直接把/etc/init.d/rc.final里面的bloziplayer相关的启动脚本给注释关了。
把/etc/profile.d/里面的脚本也给删了。

再给/etc/init.d/rc.final里加了
#联网
wpa_supplicant -iwlan0 -Dnl80211 -c /etc/wpa_supplicant.conf & udhcpc -iwlan0 &
#启动自己应用
/usr/bin/player &           

wpa_supplicant.conf
network={
    ssid="SSID"  # SSID
    psk="xxxxxxx"       # 密码
}

接着跟着大佬们继续编译东西玩！

lvgl+lv_driver都用v8.2的版本
报错了。
