Hi @hasaranga. I had similar problem but for a different screen (https://learn.sparkfun.com/tutorials/sparkfun-micromod-input-and-display-carrier-board-hookup-guide). My problem was that the SPI settings were incorrect for these pins
#define TFT_MISO xx
#define TFT_MOSI xx
#define TFT_SCLK xx
Additionally, the SPI frequency needed to be lowered in my case. I hope it helps.
No miso pin in my display. I tried to change the spi speed and mosi pin with sclk but the result is same.
I was able to use Adafruit-ST7735-ST7789 library with this panel successfully by configuring SPI1 pins manually.

Hi,
I'm trying to use this library with RP2040-PiZero board and 1.3inch display HAT. Board: https://www.waveshare.com/wiki/RP2040-PiZero Display: https://www.waveshare.com/1.3inch-lcd-hat.htm
I'm using Colour_Test example. But there is nothing on screen. Backlight is working.
Here is my User_Setup.h content:
