Unable to use TFT screen on `t-camera-plus`

[duchengyao]

I use example/sketch, no screen output.

其它功能正常，只是屏幕有背光无内容，黑屏。

TFT_eSPI @ 2.4.78 is not available, so I use TFT_eSPI @ 2.4.79 in the platformio.ini below.

选中对应驱动文件https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setup_Select.h#L78-L78

[duchengyao]

感谢回复，我使用 platformio ，在 .pio/libdeps/t-camera-plus/TFT-eSPI/User_Setup_Select.h 里面取消注释了 #include <User_Setups/Setup44_TTGO_CameraPlus.h>，我是 2.4.79 所以是第81行

https://github.com/Bodmer/TFT_eSPI/blob/ef7c02098076c9a3819c30faf7da5d4af77db008/User_Setup_Select.h#L81

屏幕有显示了，但是显示有错误，我拍了视频，如下：

另外，在编译的时候会报几个 redefined 的 warnning ，请问我需要进行哪些修改

[duchengyao]

请问是否有可以同时开启 rtsp stream（或者sd卡存储视频） 和 tft 显示 的样例

[lewisxhe]

注释默认pin配置 https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setup_Select.h

[duchengyao]

这些吗？不起作用。

https://github.com/Bodmer/TFT_eSPI/blob/eb68e056d95f0f62bc08eab9242f5855518917cd/User_Setup_Select.h#L282-L300

[duchengyao]

比如 SPI_FREQUENCY 到底应该是 40000000 还是 27000000

[lewisxhe]

注释默认pin配置 https://github.com/Bodmer/TFT_eSPI/blob/master/User_Setup_Select.h

27行

[duchengyao]

我注释了27行和取消注释SPI.begin(TFT_SCLK_PIN, TFT_MISO_PIN, TFT_MOSI_PIN);以后，正常运行了。万分感谢。

请问我为什么要取消注释SPI.begin(TFT_SCLK_PIN, TFT_MISO_PIN, TFT_MOSI_PIN);？ 按注释写的，应该TFT已经初始化过了吧

[lewisxhe]

共用总线，tft已经初始化了。但是重复初始化也不应该影响

[duchengyao]

我的意思是，应该不用取消注释那一行，也可以正常运行，因为tft已经初始化了。 但是不取消注释，确实sd卡访问不了，很奇怪。

我的问题都解决了，已经可以正常运行了，十分感谢！
