arduino spi lcd display pricelist

In this guide we’re going to show you how you can use the 1.8 TFT display with the Arduino. You’ll learn how to wire the display, write text, draw shapes and display images on the screen.

The 1.8 TFT is a colorful display with 128 x 160 color pixels. The display can load images from an SD card – it has an SD card slot at the back. The following figure shows the screen front and back view.

This module uses SPI communication – see the wiring below . To control the display we’ll use the TFT library, which is already included with Arduino IDE 1.0.5 and later.

The TFT display communicates with the Arduino via SPI communication, so you need to include the SPI library on your code. We also use the TFT library to write and draw on the display.

In which “Hello, World!” is the text you want to display and the (x, y) coordinate is the location where you want to start display text on the screen.

The 1.8 TFT display can load images from the SD card. To read from the SD card you use the SD library, already included in the Arduino IDE software. Follow the next steps to display an image on the display:

Note: some people find issues with this display when trying to read from the SD card. We don’t know why that happens. In fact, we tested a couple of times and it worked well, and then, when we were about to record to show you the final result, the display didn’t recognized the SD card anymore – we’re not sure if it’s a problem with the SD card holder that doesn’t establish a proper connection with the SD card. However, we are sure these instructions work, because we’ve tested them.

In this guide we’ve shown you how to use the 1.8 TFT display with the Arduino: display text, draw shapes and display images. You can easily add a nice visual interface to your projects using this display.

The difference between those two displays is that the cheaper one is the basic type of a LCD module. You have to find a library (or create one) to draw lines, text, etc. Also if you have troubles running it, I guess your only friend will be google.

The display from 4DSystems has a graphic processor (as oppose to a graphic controller) and that LCD module can run on it"s own without Arduino. The company provides an IDE where you can basically drag and drop buttons, pictures etc and not worry how it will be drawn. The LCD module also has GPIOs, I2C, multiple SPI and Serial channels, analog inputs, timers, etc. The company also provides support (not sure how good or bad it is) and probably a better warranty. I assume you can drive the display the same way as the cheap one (e.g. via SPI) but it"s processor would be bored while your Arduino sweating while trying to draw a straight line. So I don"t know what your project is but if you just need to hook up a few buttons, maybe read some analog inputs or some other basic things then the display can do it on it"s own. The disadvantage is that you have to learn a new programming language (whatever they use to program the LCD) but I guess it should not be too hard (especially if you"re a developer). Anyway, hopefully that explains the price difference a bit.

are you ok how fast is it gonna draw? Btw. you did not mention what arduino you want to use, if it"s one of the AVR ones, like Uno, Mega, Mini Pro,... then drawing on an 7" display (assuming 800x480) will in general be slow...but it might be ok for you so it depends on what you are after...

maybe type of the LCD (if viewing angles matter to you), the cheapest ones are not really great when you look at them from an angle (black becomes gray etc.)

This LCD Display Shield gives you a nicely mounted 1602 LCD Display snaps right on top of your Arduino UNO. With onboard buttons for easy navigation including up, down, left, right, select and reset, using your Arduino away from a computer was never easier. Use this shield to display values read in by your Arduino, display options for user inputs, choose between different programs you can run on your Arduino, etc. With a Power LED onboard and a nice blue backlit display, you"ll be able to use your Arduino"s LCD Display Shield day or night!

This shield is compatible with the "LiquidCrystal" library that is bundled with the Arduino software. Just edit the "LiquidCrystal" library"s default mapping from the LCD pins to Arduino pins to the ones for this specific shield by copying what"s shown below. Here is an example of the proper way to instantiate the LiquidCrystal class for this shield:
