Espressif SoC revision.

ESP32-S3 (QFN56) (revision v0.2)

Operating System used.

Windows

How did you build your project?

Command line with idf.py

If you are using Windows, please specify command line type.

CMD

Development Kit.

ESP32-S3-Touch-LCD-1.28

Power Supply used.

USB

What is the expected behavior?

"This example will draw a fancy dash board with the LVGL library."

What is the actual behavior?

No errors except for the single WARNING but there is no "fancy dash board". The screen is slightly lit. No image or text or anything is displayed.

Steps to reproduce.

cd %userprofile%\esp
xcopy /e /i %userprofile%\git\esp-idf\examples\peripherals\lcd\spi_lcd_touch spi_lcd_touch
cd %userprofile%\esp\spi_lcd_touch
idf.py set-target esp32s3
idf.py menuconfig

I tried different levels of EXAMPLE_LCD_BK_LIGHT_ON_LEVEL with no luck. (1, 10, 100, 1000 etc) actual

Example Configuration ---> i80 LCD controller model (ILI9341) ---> () ILI9341 (X) GC9A01

THis confused me. I think that LCD module uses SPI interface not i80. https://www.waveshare.com/wiki/ESP32-S3-Touch-LCD-1.28

suda-morris commented 2 weeks ago

Please also check if the GPIO assignment in your code matches the hardware connection. I just connect my GC9A01 LCD break out board with ESP32S3, it works fine.

oshmykov-dev commented 2 weeks ago

@suda-morris you're right the problem was with the wrong GPIO assignments.

#define EXAMPLE_PIN_NUM_SCLK           10
#define EXAMPLE_PIN_NUM_MOSI          11
#define EXAMPLE_PIN_NUM_MISO          12
#define EXAMPLE_PIN_NUM_LCD_DC        8
#define EXAMPLE_PIN_NUM_LCD_RST     14
#define EXAMPLE_PIN_NUM_LCD_CS         9

From the specification

Thank you so much!
