Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for 3.5"TFT Touch Shield with Libraries, Examples.Schematic Diagram for Arduino Due,Mega 2560 and Uno . For 8051 microcontroller user,we prepared the detailed tutorial such as interfacing, demo code and development kit at the bottom of this page.

I am messing around with TFT displays now and have been interested in my TFT displays bitmap function, however, it is very slow. when doing any other kind of colour printing/messages it is about as instantaneous as I"d expect, but when doing bitmaps it takes almost 30seconds to fully update the 320x480px screen.

Displays are one of the best ways to provide feedback to users of a particular device or project and often the bigger the display, the better. For today’s tutorial, we will look on how to use the relatively big, low cost, ILI9481 based, 3.5″ Color TFT display with Arduino.

This 3.5″ color TFT display as mentioned above, is based on the ILI9481 TFT display driver. The module offers a resolution of 480×320 pixels and comes with an SD card slot through which an SD card loaded with graphics and UI can be attached to the display. The module is also pre-soldered with pins for easy mount (like a shield) on either of the Arduino Mega and Uno, which is nice since there are not many big TFT displays that work with the Arduino Uno.

To easily write code to use this display, we will use the GFX and TFT LCD libraries from “Adafruit” which can be downloaded here. With the library installed we can easily navigate through the examples that come with it and upload them to our setup to see the display in action. By studying these examples, one could easily learn how to use this display. However, I have compiled some of the most important functions for the display of text and graphics into an Arduino sketch for the sake of this tutorial. The complete sketch is attached in a zip file under the download section of this tutorial.

As usual, we will do a quick run through of the code and we start by including the libraries which we will use for the project, in this case, the Adafruit GFX and TFT LCD libraries.

With this done, the Void Setup() function is next. We start the function by issuing atft.reset() command to reset the LCD to default configurations. Next, we specify the type of the LCD we are using via the LCD.begin function and set the rotation of the TFT as desired. We proceed to fill the screen with different colors and display different kind of text using diverse color (via the tft.SetTextColor() function) and font size (via the tft.setTextSize() function).

This TFT 3.5 Inch LCD display support 480x320 pixel resolutions. The display uses the ILI9481 graphics controller. The module includes the 5V-3.3V power conversion circuit and no additional level conversion circuitry is required. This Module can be inserted directly into the Arduino Mega2560 Board.

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

This display can be mounted on an Arduino Mega or Due. It has a fairly high resolution of 320*480 pixels and is also quite large with 3.2 inch LCD size.

3.5 inch RPi LCD V3.0 HVGA 480X320. There is a XPT2046, 74HC04D, 74HC4040D, and 2 74HC4094D chips on the back. Is there a way to determine which driver I need to use in software?

I am not 100% convinced that the distribution given works with the LCD (the item I bought is dis-continued but the seller provided another item that has identical specifications - 3.5" IPS 15fps 480x320 resolution - but I suspect it has a slightly, or altogether different, controller.

[*]Is there any way I can extract some information of what driver has been used, or tried to use, for the TFT via that half working distribution? As far as I know, a GPIO/ SPI connection will not gather connected hardware information...

I bought a display off Amazon described as [ SainSmart 3.5" inch TFT LCD 240x320 RGB Pixels Touch Screen Display Monitor For Raspberry Pi for Model B & B+] and sold by: Sain Store. What I received is the 320x480 display you described. I am also trying to verify the model before I try to set it up.

This LCD Touchscreen HAT fits snuggly on top of the Raspberry Pi, practically form fitting on top of it so as not to compromise the overall dimensions of the credit card sized single board computer. The resistive touchscreen provides you with an easy way to display information coming off of the Raspberry Pi and the OS currently running on it.

The 4:3 aspect ratio backlit LCD equipped on this HAT possesses a resolution of 480 by 320 pixels with over 65 thousand colors and an SPI interface with a 16MHz driver speed. Simply plug the 13x2 GPIO header into your desired Raspberry Pi and you"ll be able to start using your new resistive touch screen!

The TFT LCD class provides basic firmware functionalities like Init, ResetDevice, WriteDevice, WriteDataToDevice, WriteBlock and FillRectangle.

The 4:3 aspect ratio was common in older television cathode ray tube (CRT) displays, which were not easily adaptable to a wider aspect ratio. When good quality alternate technologies (i.e., liquid crystal displays (LCDs) and plasma displays) became more available and less costly, around the year 2000, the common computer displays and entertainment products moved to a wider aspect ratio, first to the 16:10 ratio. The 16:10 ratio allowed some compromise between showing older 4:3 aspect ratio broadcast TV shows, but also allowing better viewing of widescreen movies. However, around the year 2005, home entertainment displays (i.e., TV sets) gradually moved from 16:10 to the 16:9 aspect ratio, for further improvement of viewing widescreen movies. By about 2007, virtually all mass-market entertainment displays were 16:9. In 2011, 1920 × 1080 (Full HD, the native resolution of Blu-ray) was the favored resolution in the most heavily marketed entertainment market displays. The next standard, 3840 × 2160 (4K UHD), was first sold in 2013.

The first commercial displays capable of this resolution include an 82-inch LCD TV revealed by Samsung in early 2008,PPI 4K IPS monitor for medical purposes launched by Innolux in November 2010.Toshiba announced the REGZA 55x3,

HVGA (Half-size VGA) screens have 480 × 320 pixels (3:2 aspect ratio), 480 × 360 pixels (4:3 aspect ratio), 480 × 272 (≈16:9 aspect ratio), or 640 × 240 pixels (8:3 aspect ratio). The former is used by a variety of PDA devices, starting with the Sony CLIÉ PEG-NR70 in 2002, and standalone PDAs by Palm. The latter was used by a variety of handheld PC devices. VGA resolution is 640 × 480.

HVGA was the only resolution supported in the first versions of Google Android, up to release 1.5.WVGA resolution on the Motorola Droid or the QVGA resolution on the HTC Tattoo.

It is a common resolution among LCD projectors and later portable and hand-held internet-enabled devices (such as MID and Netbooks) as it is capable of rendering websites designed for an 800 wide window in full page-width. Examples of hand-held internet devices, without phone capability, with this resolution include: Spice stellar nhance mi-435, ASUS Eee PC 700 series, Dell XCD35, Nokia 770, N800, and N810.

DVGA (Double-size VGA) screens have 960 × 640 pixels (3:2 aspect ratio). Both dimensions are double that of HVGA, hence the pixel count is quadrupled.

Wide XGA (WXGA) is a set of non-standard resolutions derived from the XGA display standard by widening it to a widescreen aspect ratio. WXGA is commonly used for low-end LCD TVs and LCD computer monitors for widescreen presentation. The exact resolution offered by a device described as "WXGA" can be somewhat variable owing to a proliferation of several closely related timings optimised for different uses and derived from different bases.

A common variant on this resolution is 1360 × 768, which confers several technical benefits, most significantly a reduction in memory requirements from just over to just under 1MB per 8-bit channel (1366 × 768 needs 1024.5KB per channel; 1360 × 768 needs 1020KB; 1MB is equal to 1024KB), which simplifies architecture and can significantly reduce the amount–and speed–of VRAM required with only a very minor change in available resolution, as memory chips are usually only available in fixed megabyte capacities. For example, at 32-bit color, a 1360 × 768 framebuffer would require only 4MB, whilst a 1366 × 768 one may need 5, 6 or even 8MB depending on the exact display circuitry architecture and available chip capacities. The 6-pixel reduction also means each line"s width is divisible by 8 pixels, simplifying numerous routines used in both computer and broadcast/theatrical video processing, which operate on 8-pixel blocks. Historically, many video cards also mandated screen widths divisible by 8 for their lower-color, planar modes to accelerate memory accesses and simplify pixel position calculations (e.g. fetching 4-bit pixels from 32-bit memory is much faster when performed 8 pixels at a time, and calculating exactly where a particular pixel is within a memory block is much easier when lines do not end partway through a memory word), and this convention persisted in low-end hardware even into the early days of widescreen, LCD HDTVs; thus, most 1366-width displays also quietly support display of 1360-width material, with a thin border of unused pixel columns at each side. This narrower mode is of course even further removed from the 16:9 ideal, but the error is still less than 0.5% (technically, the mode is either 15.94:9.00 or 16.00:9.04) and should be imperceptible.

When referring to laptop displays or independent displays and projectors intended primarily for use with computers, WXGA is also used to describe a resolution of 1280 × 800 pixels, with an aspect ratio of 16:10.both dimensions vs. the old standard (especially useful in portrait mode, or for displaying two standard pages of text side by side), a perceptibly "wider" appearance and the ability to display 720p HD video "native" with only very thin letterbox borders (usable for on-screen playback controls) and no stretching. Additionally, like 1360 × 768, it required only 1000KB (just under 1MB) of memory per 8-bit channel; thus, a typical double-buffered 32-bit colour screen could fit within 8MB, limiting everyday demands on the complexity (and cost, energy use) of integrated graphics chipsets and their shared use of typically sparse system memory (generally allocated to the video system in relatively large blocks), at least when only the internal display was in use (external monitors generally being supported in "extended desktop" mode to at least 1600 × 1200 resolution). 16:10 (or 8:5) is itself a rather "classic" computer aspect ratio, harking back to early 320 × 200 modes (and their derivatives) as seen in the Commodore 64, IBM CGA card and others. However, as of mid-2013, this standard is becoming increasingly rare, crowded out by the more standardised and thus more economical-to-produce 1366 × 768 panels, as its previously beneficial features become less important with improvements to hardware, gradual loss of general backwards software compatibility, and changes in interface layout. As of August 2013, the market availability of panels with 1280 × 800 native resolution had been generally relegated to data projectors or niche products such as convertible tablet PCs and LCD-based eBook readers.

Widespread availability of 1280 × 800 and 1366 × 768 pixel resolution LCDs for laptop monitors can be considered an OS-driven evolution from the formerly popular 1024 × 768 screen size, which has itself since seen UI design feedback in response to what could be considered disadvantages of the widescreen format when used with programs designed for "traditional" screens. In Microsoft Windows operating system specifically, the larger taskbar of Windows Vista and 7 occupies an additional 16-pixel lines by default, which may compromise the usability of programs that already demanded a full 1024 × 768 (instead of, e.g. 800 × 600) unless it is specifically set to use small icons; an "oddball" 784-line resolution would compensate for this, but 1280 × 800 has a simpler aspect and also gives the slight bonus of 16 more usable lines. Also, the Windows Sidebar in Windows Vista and 7 can use the additional 256 or 336 horizontal pixels to display informational "widgets" without compromising the display width of other programs, and Windows 8 is specifically designed around a "two-pane" concept where the full 16:9 or 16:10 screen is not required. Typically, this consists of a 4:3 main program area (typically 1024 × 768, 1000 × 800 or 1440 × 1080) plus a narrow sidebar running a second program, showing a toolbox for the main program or a pop-out OS shortcut panel taking up the remainder.

XGA+ stands for Extended Graphics Array Plus and is a computer display standard, usually understood to refer to the 1152 × 864 resolution with an aspect ratio of 4:3. Until the advent of widescreen LCDs, XGA+ was often used on 17-inch desktop CRT monitors. It is the highest 4:3 resolution not greater than 220 pixels (≈1.05 megapixels), with its horizontal dimension a multiple of 32 pixels. This enables it to fit closely into a video memory or framebuffer of 1MB (1 × 220 bytes), assuming the use of one byte per pixel. The common multiple of 32 pixels constraint is related to alignment.

WXGA+ (1440 × 900) resolution is common in 19-inch widescreen desktop monitors (a very small number of such monitors use WSXGA+), and is also optional, although less common, in laptop LCDs, in sizes ranging from 12.1 to 17 inches.

SXGA is the most common native resolution of 17-inch and 19-inch LCD monitors. An LCD monitor with SXGA native resolution will typically have a physical 5:4 aspect ratio, preserving a 1:1 pixel aspect ratio.

Any CRT that can run 1280 × 1024 can also run 1280 × 960, which has the standard 4:3 ratio. A flat panel TFT screen, including one designed for 1280 × 1024, will show stretching distortion when set to display any resolution other than its native one, as the image needs to be interpolated to fit in the fixed grid display. Some TFT displays do not allow a user to disable this, and will prevent the upper and lower portions of the screen from being used forcing a "letterbox" format when set to a 4:3 ratio.

SXGA+ stands for Super Extended Graphics Array Plus and is a computer display standard. An SXGA+ display is commonly used on 14-inch or 15-inch laptop LCD screens with a resolution of 1400 × 1050 pixels. An SXGA+ display is used on a few 12-inch laptop screens such as the ThinkPad X60 and X61 (both only as tablet) as well as the Toshiba Portégé M200 and M400, but those are far less common. At 14.1 inches, Dell offered SXGA+ on many of the Latitude C-Series laptops, such as the C640, and IBM since the ThinkPad T21. Sony also used SXGA+ in their Z1 series, but no longer produce them as widescreen has become more predominant.

In desktop LCDs, SXGA+ is used on some low-end 20-inch monitors, whereas most of the 20-inch LCDs use UXGA (standard screen ratio), or WSXGA+ (widescreen ratio).

WSXGA+ stands for Widescreen Super Extended Graphics Array Plus. WSXGA+ displays were commonly used on Widescreen 20-, 21-, and 22-inch LCD monitors from numerous manufacturers (and a very small number of 19-inch widescreen monitors), as well as widescreen 15.4-inch and 17-inch laptop LCD screens like the Thinkpad T61p, the late 17" Apple PowerBook G4 and the unibody Apple 15" MacBook Pro. The resolution is 1680 × 1050 pixels (1,764,000 pixels) with a 16:10 aspect ratio.

UXGA has been the native resolution of many fullscreen monitors of 15 inches or more, including laptop LCDs such as the ones in the IBM ThinkPad A21p, A30p, A31p, T42p, T43p, T60p, Dell Inspiron 8000/8100/8200 and Latitude/Precision equivalents; some Panasonic Toughbook CF-51 models; and the original Alienware Area 51M gaming laptop. However, in more recent times, UXGA is not used in laptops at all but rather in desktop UXGA monitors that have been made in sizes of 20 inches and 21.3 inches. Some 14-inch laptop LCDs with UXGA have also existed (such as the Dell Inspiron 4100), but these are very rare.

The QXGA, or Quad Extended Graphics Array, display standard is a resolution standard in display technology. Some examples of LCD monitors that have pixel counts at these levels are the Dell 3008WFP, the Apple Cinema Display, the Apple iMac (27-inch 2009–present), the iPad (3rd generation), the iPad Mini 2, and the MacBook Pro (3rd generation). Many standard 21–22-inch CRT monitors and some of the highest-end 19-inch CRTs also support this resolution.

QWXGA (Quad Wide Extended Graphics Array) is a display resolution of 2048 × 1152 pixels with a 16:9 aspect ratio. A few QWXGA LCD monitors were available in 2009 with 23- and 27-inch displays, such as the Acer B233HU (23-inch) and B273HU (27-inch), the Dell SP2309W, and the Samsung 2343BWX. As of 2011, most 2048 × 1152 monitors have been discontinued, and as of 2013, no major manufacturer produces monitors with this resolution.

QXGA (Quad Extended Graphics Array) is a display resolution of 2048 × 1536 pixels with a 4:3 aspect ratio. The name comes from it having four times as many pixels as an XGA display. Examples of LCDs with this resolution are the IBM T210 and the Eizo G33 and R31 screens, but in CRT monitors this resolution is much more common; some examples include the Sony F520, ViewSonic G225fB, NEC FP2141SB or Mitsubishi DP2070SB, Iiyama Vision Master Pro 514, and Dell and HP P1230. Of these monitors, none are still in production. A related display size is WQXGA, which is a widescreen version. CRTs offer a way to achieve QXGA cheaply. Models like the Mitsubishi Diamond Pro 2045U and IBM ThinkVision C220P retailed for around US$200, and even higher performance ones like the ViewSonic PerfectFlat P220fB remained under $500. At one time, many off-lease P1230s could be found on eBay for under $150. The LCDs with WQXGA or QXGA resolution typically cost four to five times more for the same resolution. IDTech manufactured a 15-inch QXGA IPS panel, used in the IBM ThinkPad R50p. NEC sold laptops with QXGA screens in 2002–05 for the Japanese market.iPad (starting from 3rd generation and Mini 2) also has a QXGA display.

In June 2001, WQUXGA was introduced in the IBM T220 LCD monitor using a LCD panel built by IDTech. LCD displays that support WQUXGA resolution include: IBM T220, IBM T221, Iiyama AQU5611DTBK, ViewSonic VP2290,Hz and 48Hz, made them less attractive for many applications.

After having used VGA-based 3:2 resolutions HVGA (480 × 320) and Retina DVGA (960 × 640) for several years in their iPhone and iPod products with a screen diagonal of 9 cm or 3.5 inches, Apple started using more exotic variants when they adopted the 16:9 aspect ratio to provide a consistent pixel density across screen sizes: first 1136 × 640 (rarely: WDVGA) with the iPhone 5, 5C, 5S and SE 1st for 10-cm or 4-inch screens, and later 1334 × 750 with the iPhone 6, 6S, 7, 8, SE 2nd and SE 3rd for 12-cm or 4.7-inch screens, while devices with 14-cm or 5.5-inch screens used standard 1920 × 1080 with the iPhone 6 Plus, 6S Plus, 7 Plus and 8 Plus. The iPhone X, XS and 11 Pro introduced a 2436 × 1125 resolution for 15-cm or 5.8-inch screens, while the iPhone XS Max and 11 Pro Max introduced a 2688 × 1242 resolution for 17-cm or 6.5-inch screens (with a notch) all at an aspect ratio of roughly 13:6 or, for marketing, 19.5:9.
