ili9325 2.8 tft lcd quotation

We’ve done quite a number of tutorials on the use of several displays with Arduino boards and today we will add another tutorial to that list. We will look at the ILI9325 based 2.8″ touchscreen display shown below and how it can be used with the Arduino to deliver a better user experience for your projects.

For today’s tutorial, we will use the ILI9325 driver based, 2.8″ display from Geekcreit. The display comes as a shield so it’s ready to be used for Arduino based projects. It is an 18-bit color display with a total of 262,000 different color shades. The display has a resolution of 240 x 320 pixels with individual pixel control.

The 2.8″ TFT display used for this project comes as a shield with the form factor of the Arduino Uno. This makes it easy to connect the shield to boards like the Uno, Mega and Due, as all we need to do, is plug it directly into the board, eliminating all the mess made by wires.  Plug the display to the Arduino as shown in the image below.

The code for this tutorial is heavily reliant on a modified version of Adafruit’s TFT LCD,GFX and touchscreen libraries. These libraries can be downloaded from the links attached to them.

Next, we declare the colors to be used with their hexadecimal values and we create an object of the Adafruit TFTLCD library, indicating the variables used to represent the pins of the Arduino to which the display is connected.

We start by initializing the serial monitor and the display. After this, we set the orientation of the LCD and fill the screen with a black color to serve as the background.

ili9325 lcd provide the touch interface in smartphones, which are vital for them to function. Alibaba.com stocks a stunning range of high-tech ili9325 lcd with vibrant color depictions. Truly crystal-clear displays of ili9325 lcd are available covering various brands and models such as the Samsung Galaxy Edge 2, OnePlus 7T, Samsung Galaxy C5, and many more.

ili9325 lcd are the most commonly used displays, as they produce great image quality while consuming low power. Rather than emitting light directly, they use back lights or reflectors to produce images, which allows for easy readability even under direct sunlight. ili9325 lcd are energy-efficient, and are comparatively safer to dispose of, than CRTs. ili9325 lcd are much more efficient when it comes to usage in battery-powered electronic equipment, due to their minimal power consumption.

Some other advantages of ili9325 lcd over the CRT counterparts are - sharper images, little to no heat emission, unaffected by magnetic fields, narrow frame borders, and extreme compactness, which make them very thin and light. Some types of ili9325 lcd are transmissive, reflective, and transflective displays. Transmissive displays provide better image quality in the presence of low or medium-light, while reflective displays work best in the presence of bright light. The third type of ili9325 lcd, transflective, combine the best features of both the other types and provide a well-balanced display.

I have been running into problems when I wanted to actually display something on the screen using TFT LCD library (https://github.com/adafruit/TFTLCD-Library) (and the GFX library (https://github.com/adafruit/Adafruit-GFX-Library))...

Connect the seventh pin RST (Reset) to the Arduino Reset line. This will reset the panel when the Arduino is Reset. You can also use a digital pin for the LCD reset but this will save us a pin.

It should be 0x9328 or 0x9325 so if you see something like 0x8328 that means that the D8 pin is not wired correctly and if you get 0x9228 then pin D0 is not wired correctly.

Adafruit is also selling a shield version of you display and I think you can use this to verify you pin assignment. With this: https://github.com/adafruit/TFTshield/blob/master/schem.png

I just got my teensy3 displaying the graphicstest on my LCD. Your description here of how to do it was just fine, though it took me a couple of tries to get the wiring right (my fault, though)

I got this going as well thanks to your guidance. While I was fiddling with the pinouts etc. in pinmagic, I did a couple of other things, in Adafruit_TFTLCD:

inline Adafruit_GFX& operator() (uint8_t x, uint8_t y,uint16_t c) {setCursor(x,y); setTextColor(c); return *this;} //use along w Streaming.h to support: tft(col,line,color)<<"a="<

inline Adafruit_GFX& operator() (uint8_t x, uint8_t y,uint16_t c,uint8_t s) {setCursor(x,y); setTextColor(c); setTextSize(s); return *this;} //use along w Streaming.h to support: tft(col,line,color,size)<<"a="<

They are not using the current library, as you guessed. I tried patching pin_magic.h with the teensy 3 mods, but more is required for the current TFTLCD library. The library now supports DUE, and the constructor does a lot of work mapping the control pins into port register access for set/clear operations. Maybe the teensy equivalent would be to use

And I measured 32.7ma at 3.3v for the TFTLCD, so I powered it from the teensy 3 3.3v pin. This is on older Adafruit TFTLCD, http://www.adafruit.com/products/335

OK, maybe I"m confused, but does that library drive the Adafruit display in 8-bit mode (as described at https://learn.adafruit.com/adafruit-2-dot-8-color-tft-touchscreen-breakout-v2/8-bit-wiring)? The TFTLCD library has the disadvantage of needing more pins, but my impression was that it could achieve a higher throughput of data to the display, or am I mistaken in that as well?

Well, this is awkward. I had a 2.8" ILI9325 screen from Adafruit working on a Teensy 3.0 a couple of years back. I just tried to rebuild the code for that and I seem to have lost some files. Specifically I"m looking for the right Adafruit_TFTLCD library (well, I think that"s all I"m looking for). The current library from Github doesn"t compile with a Teensy3, and I recall I had to edit the pin_magic file as per ZTiK.nl (earlier in this thread). But the later files from Github look different now. I don"t seem to be able to go back to an earlier branch on Github.

I can see Paul has posted an ILI9341_t3 library, but mine is an ILI9325. Has anyone got a working copy of the library that works with my combination posted somewhere? I"d rather not upgrade the hardware at this stage, the problem I have is software.

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.

as you can see the string is "www.keil.com" but it have been duplicated in lcd and uncleear to read, and only fill only half of LCD Screen hase been colored.

Add a touch to your Arduino project with a large touchscreen display shield with a built-in microSD card connection. This TFT display is big (2.8" diagonal) bright and colorful! 240x320 pixels with individual pixel control. It has way more resolution than a black and white 128x64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.
