pi pico with waveshare pico-lcd-2 display problem

[cuu123]

pi pico with waveshare pico-lcd-2 display is not working. howto correct? please help
here is the setup file
my test file is examples\Test and diagnostics\Colour_Test

#define USER_SETUP_INFO "User_Setup"

Have you followed the instructions here:
https://www.waveshare.com/wiki/Pico-ResTouch-LCD-3.5

Have you run the Read_User_Setup sketch and checked the serial output is correct?

[cuu123]

Thanks for your reply. I followed the instructions here:
https://www.waveshare.com/wiki/Pico-LCD-2

And I run the Read_User_Setup sketch and paste the serial output as follows:
Please help me find out what the problem is.

[code]
TFT_eSPI ver = 2.5.23
Processor = RP2040
Transactions = Yes
Interface = SPI
Display driver = 778B
Display width = 240
Display height = 320

MOSI = GPIO 11
SCK = GPIO 10
TFT_CS = GPIO 9
TFT_DC = GPIO 8
TFT_RST = GPIO 12

TFT_BL = GPIO 13

Font GLCD loaded
Font 2 loaded
Font 4 loaded
Font 6 loaded
Font 7 loaded
Font 8 loaded
Smooth font enabled

Display SPI frequency = 20.00
[/code]

Are you using the Arduino IDE and Earle Philhower's board package?

[cuu123]

Yes, Arduino IDE 1.8.19 and Earle Philhower's board package 3.0.0.

I confirmed the environment and rerun the Read_User_Setup sketch.

Comment out the following line in the setup file thus:
//#define RPI_DISPLAY_TYPE

[cuu123]

It works! Thanks for your kind help!!
