1.44" SPI 128x128 TFT

I've gotten a 1.44" SPI 128x128 TFT.
It is a Red PCB with Yellow headers and 1.1 on it.
I've run an ino from another thread called ST7735_readreg.ino and gotten these results

Bi-directional Read registers
controller reg(0x01) = 0x00
ST7735R reg(0x04) = 0x7C89F0
ST7735R reg(0x09) = 0x610000
ST7735R reg(0x0A) = 0x08
ST7735R reg(0x0B) = 0x00
ST7735R reg(0x0C) = 0xFF
ST7735R reg(0x0D) = 0xFF
ST7735R reg(0x0E) = 0x00
ST7735R reg(0x0F) = 0xFF
ST7735R reg(0x2E) = 0x00
ST7735R reg(0xDA) = 0x7C
ST7735R reg(0xDB) = 0xFF
ST7735R reg(0xDC) = 0xF0

Which I believe means it's an ST7735 of some sort.

I am trying to use sumotoys library from here but I still can't seem to get it to work even after edditing the setting to make sure I'm using the correct display.

I have quite a few questions to ask about the screen.

  1. is the VCC 3.3v or 5v?
  2. is the logic 3.3v or 5v?
  3. Can this library be used with an Arduino Nano?
  4. If the Logic level is 3.3v is a CD4050BE sufficient?
  5. Did Sumotoy ever finish the libraries?

I would appreciate any help

EDIT. Okay I've managed to get an output using the ADAFruit ST7735 library but still struggling with any others.

  1. is the VCC 3.3v or 5v? 5V (3.3V if you short out regulator)
  2. is the logic 3.3v or 5v? 3.3V
  3. Can this library be used with an Arduino Nano? Yes with level shifters
  4. If the Logic level is 3.3v is a CD4050BE sufficient? Yes
  5. Did Sumotoy ever finish the libraries? Don't know

I suggest that you look at Bodmer's libraries.
Yes, it looks like Sitronix ST7735S.

If you use a CD4050 on the SDA pin, you lose the ability to read the bidirectional pin.
Life is much simpler if you use a proper 3.3V Arduino. e.g. Zero, Due, ... 3.3V Pro_Mini.

The Nano is 5V only. Disconnect display. Program via USB. Remove from USB. Connect display. Power with external 3.3V supply. Tear out your hair.
