## Troubleshooting
|
||||
|
||||
* Why the LCD doesn't light up?
|
||||
* Check the backlight's turn-on level, and update it in `EXAMPLE_LCD_BK_LIGHT_ON_LEVEL`
|
||||
* Please pay attention to the level used to turn on the LCD backlight, some LCD module needs a low level to turn it on, while others take a high level. You can change the backlight level macro `EXAMPLE_LCD_BK_LIGHT_ON_LEVEL` in [lvgl_example_main.c](main/rgb_lcd_example_main.c).
|
||||
* No memory for frame buffer
|
||||
* The frame buffer of RGB panel is located in ESP side (unlike other controller based LCDs, where the frame buffer is located in external chip). As the frame buffer usually consumes much RAM (depends on the LCD resolution and color depth), we recommend to put the frame buffer into PSRAM (like what we do in this example). However, putting frame buffer in PSRAM will limit the maximum PCLK due to the bandwidth of **SPI0**.
|
||||
* LCD screen drift
