St77735 arduino wiring and coding is very easy.There is new method of connecting st7735 diaplay to arduino.I will show you the proof.
Today iam going to show you how to interface arduino st7735 without wiring. Yes its possible and i made it.
What is St7735
The stT7735 is an Arduino compatable TFT color display which can display color images, fonts, animations, graphics and video on it. There are many libraries available.The display is 1.8 inch in size.
The library used is
#include <SPI.h>
#include <Ucglib.h>
Include these libraries in Arduinodroid mobile app to drive the ST7735 display with arduino.
You can use adafruit st7735 also.
Specifications
* Display driver ic - ST7735
* Power - 3v to 5V DC
* Resolution - 128*160
* Protocol of interfacing - SPI
* SD card drive direct - Yes
Components Required :
For this project we need,
Arduino uno
Resistor - 100 ohms
Female to Female jumper wire.
....
The display has 16 pins in total from left to right.The eighth pin should bent outwards which is shown in the above figure.
The resistor is placed on arduino pin 0 and pin 7.
Now we are going to insert display into arduino pins directly.
We have connected the display to arduino.The display is connected in the arduino pins pin 0 from right upto the gnd label on arduino. So out of 16 pins of display the 8th pin which is bent outward should be connected.
Here we are making use of ICSP pin(In circuit Serial Programming) on arduino board to connect the 8th pin.
So now we connected the wire to one of the ICSP pin. The connection to display is completed. Now upload the program to arduino using arduinodroid mobile app or arduino IDE desktop version.
....
Now we can see the display is working properly after powering. In this way we can work with ST7735 display without any risk of wiring..
