128x160 1.8" TFT display with ST7735 controlled by ESP32

   I give an 1.8" TFT display with 128x160 resolution. It use ST7735 as driver.
   I wanted to use together with an ESP32 development board and first I search information about this connexion but just two article and an topic on Arduino forum was usefull.
   First usefull article was 128×128 Colour LCD to ESP32 from www.xtronical.com. Schematic for connexion is
It used Xtronical ST7735 library derivated from Adafruit ST7735 library... I tested, but I can't display all info in all four modes (0, 90, 180 and 270 degree) even if I change resolution in library as 128x160 not 128x128.
  I made 128x160 1.8" TFT display with ST7735 controlled by ESP32 to be more clear
   In article Cheap 1.77 Inch TFT-screen on ESP32 from https://www.hackster.io/ and  an topic on Arduino forum I discover Bodmer's TFT_eSPI library. After few time testing, I can see ok info on display.
   My changed User_Setup.h works fine for me, see in 128x160 1.8" TFT display with ST7735 controlled by ESP32 (2)

1.8" TFT display with ST7735B

   I buy an small 1.8" TFT display with ST7735B driver and I try to connect directly to Arduino Uno board as I see on net... but result was not good... display is almost white
and just disconnect accidentaly the GND I can see something...
   So, I search on Arduino forums and on net (article INSTRUCTABLES: Arduino TFT display and font library ) and I found a solution like Nokia 5110 monochrome display .. I put 1k resistor on each data pins to Arduino to display:
and I tested more Arduino library for this display with ST7735 driver (from Adafruit, TFT library, ucglib library, etc) and I made  move to see .. movie is named ST7735B display with Arduino board

NOTE: Original article is in roumanian language, see Afisaj TFT de 1,8" cu driver ST7735B !!!
