@whycanservice 看到了~~ @jerrychen 打算画转接板不~~ 我有类似的屏，还没点亮~也是按照厂家的配，连背光都不亮~要是画转接板，记得@一下我。啊哈哈。

JerryChen LV 4

@soso90 就1楼的代码片段2就是卖家给的，我只是把他转换为这个平台的格式了

JerryChen LV 4

@soso90 应该不画，也不会画（都忘记怎么画板了），就一块这个屏，买来玩玩的

soso90 LV 6

@jerrychen 方便加个qq不，我断断续续也在调mipi的屏，也是7701s~ qq：491532763

soso90 LV 6

@jerrychen 有没有测试镜像，方便发我测试一下~~屏已经买了。怕硬件没飞好线~

soso90 LV 6

@jerrychen
果不其然，按照你修改的。没有点亮。驱动是加载了。但是只亮背光。有可能是转接板有问题。看到贴子的话，方便帮我试试我的镜像？或是分享你的镜像给我。谢谢

@soso90 在【分享】D1S新增一款MIPI屏[480*480] ST7701S 中说：

线

已邮件发给你了~~~不好意思，有段时间没上来了

JerryChen LV 4

测试固件，上传备份下~~~

启动后，执行下面命令可亮屏：

lv_examples 0

@jerrychen 非常感谢大佬百忙之中传上固件。实际测试后还是不行。应该是我的硬件有问题。万分感谢。后续我有进展，继续跟进~~

重新手动飞线，能亮了。这个镜像也可以。。。兜兜转转，才搞定硬件。谢谢楼主，完楼~~
