Full color display with wide viewing angle. This is version without CS pin.
This 1.3″ IPS LCD is a full color display with a high resolution of 240 x 240 pixels and a wide viewing angle.
These full color displays can pack a lot of information into a small 1.3″ form factor with 260PPI (Pixels Per Inch).
When you find these modules for sale, they are often mistakenly identified as an OLED display but they are in fact IPS LCD which has a similar wide viewing angle to OLED.
The module operates at 3.3V, so if using with a 5V MCU, be sure to include logic level shifters on the data lines to prevent possible damage. The circuitry on the back of the module is just a transistor and a few resistors and capacitor to provide backlight control. The module does not have a 3.3V regulator on it and so must be powered from 3.3V.
The video below shows two of these displays being used for the Adafruit Uncanny Eyes application being run from a Teensy 4.1 microcontroller. This application comes with the Teensyduino software. It cannot be run on a regular AVR Arduino as the processing requirements are too great.
This display incorporates the SPI interface which provides for fast display updates.
Since it is a write only device, it does not need the SPI MISO line hooked up. The module also does not bring the CS pin out to the interface which helps to lower the pin count. The downside is that it cannot be used with other SPI devices on the same bus at the same time.
Connection to the display is via a 7-pin header.
1 x 7 Header
These are interesting modules to work with since they have full color and graphical capability with good library support.
These modules are breadboard friendly with a 7-pin header on the back that can be inserted into a solderless breadboard or a 7-pin female connector can be used to connect to it if the display is to be mounted. The display is mounted on a PCB which helps provide support, but be sure to press on the header pins when applying pressure to insert them into a breadboard and not press on the glass to avoid possible damage.
Though these displays can seem to be a bit intimidating to use at first, especially with a lack of a CS pin, just follow these steps to get up and running very easily.
Connect VCC to 3.3V and GND to ground on the MCU.
Connect the SPI lines. In our example we are using hardware SPI as it gives the best performance. Module SCL pin goes to the SPI SCK line on the MCU and module SDA goes to the SPI MOSI line on the MCU. These pins will be different depending on which MCU your are using. The SPI SCK is pin 13 on Uno and pin 52 on Mega 2560. MOSI is pin 11 on Uno and pin 51 on Mega 2560.
Connect DC to pin 8 and RST to pin 9. The BLK pin can be left unconnected which will leave the backlight on all the time.
If you are using a 3.3V MCU, these lines can be connected directly. If you are using a 5V MCU, then be sure to use a logic level converter like shown at the bottom of the page.
Install the Arduino-ST7789-Library. You will need to manually download it from the GitHub site as it is not available via the Arduino IDE library manager. This library is a modified version of the original Adafruit library which makes it easy to use with the displays that do not have a CS pin as well as those that do. https://github.com/ananevilya/Arduino-ST7789-Library
The program below is a modified version of the example program that gets installed with the library. Mainly it was pruned down in size and the changes below already incorporated.
If you instead want to use the example program, make the following changes.
Uncomment this line: //Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST); //for display without CS pin
Comment out this line: Arduino_ST7789 tft = Arduino_ST7789(-1, TFT_RST, TFT_MOSI, TFT_SCLK, TFT_CS); //for display with CS pin and DC via 9bit SPI
This change uses the hardware SPI lines on the MCU for fastest operation. You can also use Software SPI by uncommenting this line instead: //Arduino_ST7789 tft = Arduino_ST7789(TFT_DC, TFT_RST, TFT_MOSI, TFT_SCLK); //for display without CS pin which is slower, but allows you to use any pins you want for the SPI interface.
