1.8 inch tft display arduino for sale
I bought this LCD Display for a university course that I"m taking. The screen itself works amazingly with the breadboard that I had on hand and the tm4c123 microcontroller that we all used in the class. On both sides of the screen are indicators of what each pin should be assigned/connected to on the microcontroller. A big plus with this screen in comparison to others on the market is that it comes with connector pins connected to it already. Many people in my class had to learn how to solder and sloppily connected external pins to their other screens. That"s most certainly not a problem here! Additionally, this screen had an SD card, if i remember correctly, that allows for more functionality. The screen has a full range of colors and allows both text and manually imported sprites to be displayed onto it. I"m not too sure if that all deals with the drivers I mention later or the screen itself, but its most certainly a plus in its own aspect. The LCD is built well and at no moment in time was I scared about it breaking - I even remember throwing it in my backpack connected to a bunch of wires while rushing to class on multiple occasions.
The only complaint that I have with this screen is the lack of "drivers" that it has to display more complicated graphics. One specific example that I remember dealing with was that there is no horizontal orientation change feature. To display graphics horizontally, I had to rotate them in photoshop manually and import them into my program like that. This made things like positioning the sprites and graphics and, more importantly, edge detection more complicated as I had to account for the changed position basis (originally being the bottom left corner but being changed to the top left for the sprites when the screen itself is rotated).
This is a single-chip controller/driver for 262K-color, graphic type TFT-LCD. It consists of 396 source line and 162 gate line driving circuits. This chip is capable of connecting directly to an external microprocessor, and accepts Serial Peripheral Interface (SPI), 8-bit/9-bit/16-bit/18-bit parallel interface.
Download each library and unzip the folders. Rename them to "Adafruit_ST7735" and "Adafruit_GFX" and place each folder inside your Arduino Libraries folder. I"ve attached a screenshot of the libraries in the correct folder. Once installed, you are ready to operate the screen! Inside the Adafruit ST7735 library is a file called graphicstest.ino which you can upload to your Arduino and it will run through a number of functions that draw objects to the screen. However, this file will need some altering to adapt the pins to your layout.
Alternatively, you can copy/paste the code below into the Arduino IDE and upload it. This is a modified version of Adafruit"s graphictest.ino, the primary difference being the assignment of pins. I also played with the code a bit to see what kind of functions there are. Let me know if you experience any issues with code. It worked fine for me./***************************************************
Only an small advice for those who want to rotate to rotate the text you have to use the instruction tft.setRotation (2); the number can be 0,1,2,3
