Unable to light up the screen while running wifi clock #72

FLoutione · 2024-07-13T11:09:03Z

I am using ESP32-S3-Touch-LCD-4.3, and when running the example WiFiClock in ESP32_Siald_Panel, the serial port keeps outputting, but the screen does not respond. I would like to know where the problem lies.

The serial debugger keeps looping out this information.

Now I have successfully started running this wifi clock project, but there is another issue where the displayed time and other information keeps scrolling upwards. I couldn't find any code in the code that has this feature. Can you provide a solution?

rolloo · 2024-07-14T11:07:31Z

#define ESP_PANEL_LCD_RGB_CLK_HZ (14 * 1000 * 1000)

FLoutione · 2024-07-14T12:53:22Z

If it's still sliding, should we continue to decrease ESP-PANEL_LCD_RGB_CLK.HZ

Hi @FLoutione, this is an RGB screen drift issue. Please check here to solve it. And it's better to set LVGL_PORT_TASK_CORE to ARDUINO_RUNNING_CORE in file lvgl_port_v8.h (code).

After burning the program, the serial port keeps outputting this message, and there is no feedback on the display screen. Can you help me check what the problem is?

I think the reason may be related to the USB CDC Mode configuration in the Tools menu. Please refer to the following guide:

That's not the reason. I've been using UART port all along, and USB CDC On Boot is also disabled.

Will you be able to see additional logs if you upload other examples?

I tried burning it once using a USB port and then switched to using a UART port, and surprisingly, it started running successfully. I have another question. I want to print and display Chinese fonts on this board, but the Chinese font that comes out is a box. How can I make it display correctly.

You can refer to the official LVGL documentation, which includes instructions on how to use custom fonts.

@FLoutione Does the touch controller also work?
