没看出来是怎么不对的?

从上往下滑,Y坐标先变大后变小。正常应该是逐渐变大

可能gt911芯片里面固件有问题,可能触屏质量有问题,找一下卖家,看怎么说。

嗯,在联系卖家,感觉这玩意没技术支持,卖家也不懂

显示已经ok了。目前调试触摸X轴坐标正常,Y轴坐标不对,参考了很多配置参数解决不了。有哪位调试过这款屏触摸吗

#5 Re: 全志 SOC » 贡献个V3S的原理图,顺便问下RGB数据线高低位的问题 » 2018-03-28 17:53:30

哦,我以为可以通过修改驱动解决,50pin的液晶屏高低位刚好和40pin的反序

不可以调整, 否则颜色会不对。

再次验证, 一点问题都没有。

怎么把tinymix设置的两个参数的默认值改一下,现在每次启动都要重新配置一下

我大概明白原因了, 应该解压缩 buildroot-v3s-20171122.zip 改名.config

是的,都没理解这句话,谢谢各位

晕哥 说:

这个是buildroot源码, 不是根文件系统哦。
根文件系统是编译后的这个文件:  output/images/rootfs.tar

就是用这个源码编译的根文件系统,配置文件用的楼主的,启动后就一直提示错误然后重启

根文件系统配置用了楼主的,启动时打印这个错误Starting init: /sbin/init exists but couldn't execute it (error -8),换了张卡也一样,怎么解决,是不是还是配置问题

新入坑的小白请教,static int fbtft_request_gpios_dt(struct fbtft_par *par)这个函数是添加到哪里
