How to diagnose and run RP2040 Pico + PicoDisplay ST7789

[pszecho]

Hi and welcome everyone!
I'm try to run this library on Pi Pico RP2040 board and Pimoroni Pico Display with ST7789 1.14” 240x135.
What i did after installing the library:

User_Setup_Select :
//#include <User_Setup.h>
and
#include <User_Setups/Setup138_Pico_Explorer_Base_RP2040_ST7789.h>

Setup138_Pico_Explorer_Base_RP2040_ST7789 :
//#define TFT_WIDTH 240
#define TFT_WIDTH 135
#define TFT_HEIGHT 240

In my understanding if I comment "User_Setup" I just need modify "Setup138_Pico_Explorer_Base_RP2040_ST7789" - where I changed the resolution to 135

after that I try to run example "colour_test" without any effect (black screen)

From example "Read_User_Setup" I have this feedback:

TFT_eSPI ver = 2.5.43
Processor = RP2040
Transactions = Yes
Interface = SPI
Display driver = 7789
Display width = 135
Display height = 240

R0 x offset = 52
R0 y offset = 40
MOSI = GPIO 19
SCK = GPIO 18
TFT_CS = GPIO 17
TFT_DC = GPIO 16

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

Display SPI frequency = 40.00

This board and display works on the GFX library but I want to run this TFT_eSPI lib

I also did some tests with esp32 and GC9A01 display and the results are:

• based on Setup 200 and only mapping SPI pins for my connection
  esp32 + GC = OK
  pico + GC = OK

• based on Setup 136
  esp32 + st7789 = ok
  pico + st7789 = NOK - I try different config of communication - with and without RST pin without results
