The ST7789 TFT module contains a display controller with the same name: ST7789. It’s a color display that uses SPI interface protocol and requires 3, 4 or 5 control pins, it’s low cost and easy to use. This display is an IPS display, it comes in different sizes (1.3″, 1.54″ …) but all of them should have the same resolution of 240×240 pixel, this means it has 57600 pixels. This module works with 3.3V only and it doesn’t support 5V (not 5V tolerant).
The ST7789 display module shown in project circuit diagram has 7 pins: (from right to left): GND (ground), VCC, SCL (serial clock), SDA (serial data), RES (reset), DC (or D/C: data/command) and BLK (back light).
As mentioned above, the ST7789 TFT display controller works with 3.3V only (power supply and control lines). The display module is supplied with 3.3V (between VCC and GND) which comes from the Arduino board.
To connect the Arduino to the display module, I used voltage divider for each line which means there are 4 voltage dividers. Each voltage divider consists of 2.2k and 3.3k resistors, this drops the 5V into 3V which is sufficient.
The first library is a driver for the ST7789 TFT display which can be installed from Arduino IDE library manager (Sketch —> Include Library —> Manage Libraries …, in the search box write “st7789” and install the one from Adafruit).
this post shows how to interface PIC16F887 microcontroller with 16×2 LCD screen (with HD44780 controller), the compiler used in this example is Microchip MPLAB XC8 (MPLAB X IDE with MPLAB XC8 compiler).
The 16×2 LCD screen has 2 rows and 16 columns which means we can write up to 32 character. There are other screens with the HD44780 controller such as: 16×1, 20×4 …
The purpose of this guide is to get your 0.96″ color LCD display successfully operating with your Arduino, so you can move forward and experiment and explore further types of operation with the display. This includes installing the Arduino library, making a succesful board connection and running a demonstration sketch.
Although you can use the display with an Arduino Uno or other boad with an ATmega328-series microcontroller – this isn’t recommended for especially large projects. The library eats up a fair amount of flash memory – around 60% in most cases.
(As the display uses the ST7735S controller IC, you may be tempted to use the default TFT library included with the Arduino IDE – however it isn’t that reliable. Instead, please follow the instructions below).
Please check that the library has been installed – to do this, select the Sketch > Include Libraryoption in the IDE and scroll down the long menu until you see “ER-TFTM0.96-1” as shown below:
The display uses the SPI data bus for communication, and is a 3.3V board. You can use it with an Arduino or other 5V board as the logic is tolerant of higher voltages.
The library used is based on the uTFT library by Henning Karlsen. You can find all the drawing and other commands in the user manual – so download the pdf and enjoy creating interesting displays.
The provided display driver example code is designed to work with Microchip, however it is generic enough to work with other micro-controllers. The code includes display reset sequence, initialization and example PutPixel() function.
Please see the DT028CTFT for reference designs. The schematics between the A and the C are the same with the exception that the A does not have the IPS interface.

This tutorial describes how to implement decimal counter which will increment from 0000 to 9999 ; in multiplexed seven segment display using PIC18F2550 in PROTEUS ISIS.
Multiplexing is required when we want to interface 3 or 4 or even more such displays with MCU ssince it we go for normal way it will require lots of IO port.This means to turn on one at a time, extra brightly, and scan through all the digits fast enough that the eye blurs the ON and OFF.
Instead, 4 NPN transistors are used as switches to connect or disconnect the cathode terminals from Gnd. When the base of the NPN transistor is high, the transistor conducts and corresponding digit’s common cathode is connected to GND. Therefore, the transistor selects which displays is active. The conduction of the transistors are controlled by RA0 through RA3 pins of PORTA. Suppose, if we want to display 7 in the units digit place, then segments a, b, and c should be turned on first (which means RB0, RB1, RB2 are 1 and RB3-RB6 are 0) and then RA0 should be pulled up (while keeping RA1-RA3 low) so that only units digit display will be active. In order to display all 4 digits, each seven-segment display is activated sequentially using an appropriate refresh frequency so that it will appear that all the them are turned on at the same time.
We have four 7-segment displays connected to the same PORTB on the PIC18F2550. Because the circuit is connected in this way we have to multiplex the output.
After the c code is successfully compiled, a HEX file is generated.For simulating with PROTEUS ISIS hit run button and and then you will get above output.
we can drive more than one Seven Segment Display by using a technique called ‘Multiplexing’. This technique is based on the principle of Persistence of Vision of our eyes. If the frames change at a rate of 25 (or more) frames per second, human eye can’t detect that visual change. Each display is turned on above this rate and our eyes will think that the display is turned on for whole the time.
We have used Common Cathode Seven Segment Display in this example. Pins RD0 – RD6 are connected to the A – G of the display. This will count from 0000 to 9999.
