* 1.8-inch SPI serial screen with backplane module, requires at least 4 IO drivers
* Size: 1.8 inch SPI serial bus
* Resolution: 128*160
* Driver IC: ST7735
* The features of this module:
* 1. Support Arduino various MCU in-line without any wiring
* 2. Integrated voltage regulator IC, support 5V or 3.3V power supply
* 3. Onboard level shifting scheme, truly compatible with 5V/3.3V IO level. Support a variety of microcontroller IO connections
* 4. Integrated SD card expansion circuit,
* 5. Reserve SPI FLASH font circuit to facilitate extended application
I found this pinout table :

I also tried the following code with ESPHome but the screen remains white:

// Draw the outline of a rectangle with the top left at [50,60], a width of 30 and a height of 42
it.rectangle(50, 60, 30, 42);
// Draw the same rectangle, but this time filled.
it.filled_rectangle(50, 60, 30, 42);
// Circles! Let's draw one with the center at [25,25] and a radius of 10
it.circle(25, 25, 10);

it.filled_circle(25, 25, 10);
As indicated in my post I have the 1.8 Inch TFT Color Screen LCD.
I confirm that this same screen works correctly with an Arduino Nano W module so it’s either a wiring problem on my ESP module or a problem in my configuration.
