Hello @atrus2905 , Yes, you can connect to GPIO_D(IO38) which can output PWM

Hi @Anand , The zip file contains a PDF version of the schematic diagram. And please refer to this post: https://forum.elecrow.com/index.php?p=/discussion/comment/699#Comment_699

Yes, of course

Hello @maxtory , Please refer to https://github.com/Saur0o0n/PIDKiln

@mjasinsk This may be because your router's intranet cannot achieve TCP communication. Please try to use a mobile phone to open a hotspot, and then use another mobile phone to connect to GrowCube through this hotspot WiFi to see if it can connect.

(Quote) May I kindly ask which hardware version is your HMI？

Please try to lower the frequency of 7-inch a little bit in gfx_conf.h to 10000000: cfg.pin_henable = GPIO_NUM_41; cfg.pin_vsync = GPIO_NUM_40; cfg.pin_hsync = GPIO_NUM_39; cfg.pin_pclk = GPIO_NUM_0; cfg.freq_write = 10000000;

I noticed that you created a new libraries directory under the Arduino libraries directory. This should not be like this. (Image) Instead, you should directly put all the libraries (such as lvgl, etc.) under the Arduino libraries directory.

When set the pinmode to input mode, it is usually floating mode. When nothing is connected, the pin state is unstable and may change due to external electromagnetic interference. This problem will not occur when connecting sensors or other modules.

The screen signal generated by esphome is not as stable as arduino. The screen will be black after a while. esp32 cannot generate the speed required by the driver IC. If we change to a new screen with other screen driver IC, it can display normally.
