Features for the 1.8 Inch LCD TFT  Display 128X160 SPI Serial Port With SD Card Holder

  • Resolution: 128X160
  • Driver IC: ILI9163/ST7735
  • Module with regulator IC supports 3.2V/5V power supply
  • With an SD cardholder, you can do experiments like a digital photo frame
  • The module reserves the Nokia 3310/5110 interface, supports the 1602 interface and directly plugs in and out.

IO for streamlined wiring: (only 3 IOs after optimization) 1.8 Inch LCD TFT  Display 128X160 SPI Serial Port With SD Card Holder

  • 1. RST– directly connected to the microcontroller reset signal terminal, this IO can save
  • 2. D/C– is connected to a low level, and the chip selection is long-term effective.
  • 3. D/C–connected to IO control register selection
  • 4. DIN–connected to IO control data transmission
  • 5. CLK–connected to IO control SPI bus
  • 6. BL–connected to the high-level chip 3.3V backlight is always bright, then this IO can save

IO for standard wiring: (6 IO)

  • 1. RST–connected to IO control LCD reset
  • 2. CE–connected IO control chip selection
  • 3. D/C–connected to IO control register selection
  • 4. DIN–connected to IO control data transmission
  • 5. CLK–connected to IO control SPI bus
  • 6. BL–connect IO control backlight on or off or PWM control brightness

This is the step that I wish I had been able to find more easily when I started with this board. After I received the screen and realized I didn’t know how to hook it up I turned to the Adafruit guide for their product.

At first, it looked like the pin layout was different but otherwise, the two displays were interchangeable and able to run the Adafruit Graphics library (more on the code in the next step). However, when I hooked up my board following the Adafruit guide, my display sort of work. It did display text and drawings, but there was a lot of noise in the image and the images were streaky down the screen. It also had a bright glow along the top of the screen that interrupted the image quality. I thought it was because I was running the screen on 5V and it needed lower power. I tried 3.3V and the display got worse. After about 10 minutes of regretting my eBay purchase and wishing I had gone with the Adafruit board, I decided to google my problem and found this helpful article about a similar problem:

In short, you need 1k Ohm resistors between 5 of the connections. You can see where the resistors go in the Fritzing diagram. The second picture is a table of the connections between pins on the display and Arduino. I’ve listed them below and indicated if the connections require a resistor.

RST – Arduino Pin 7 – 1k Resistor

CS – Arduino Pin 9 – 1k Resistor

DC – Arduino Pin 8 – 1k Resistor

DIN – Arduino Pin 11 – 1k Resistor

CLK – Arduino Pin 13 – 1k Resistor

Vcc – 5V

BL – 5V

GND – GND
