It is available in an Arduino shield compatible pinout for attachment. The TFT driver is based on ILI9325DS with 8bit data control interface. The shield works with both 3.3V and 5V. OPEN-SMART 3.0' 240. 400 TFT LCD Shield Breakout Module for Arduino Displays. This is a 3.0 inch TFT LCD expansion board. This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller.It leads out the pins of the TFT. This is a 3.0 inch TFT LCD expansion board. This display has a.
This section is about displays. Mainly different types of controllers (with or without display panels). Refer to another menu for more about display panels and quality.FT80x and FT81xThe FT800 is a graphic controller targeted for embedded applications to generate high-quality UIs. It has a rich programming API and contains built-in antialiasing, color dither, sprites, fonts etc. It also has built-in audio capabilities. It only supports 512×512 pixels.FT801 is basically a FT801 with capacitive touch screen support with up to 5 touches and gesture detection. The FT800 pins for resisitive touch are replaced by pins for touch controller I2C interface(such as FT5x06).
According to docs, existing touch code shall be compatible. It’s compatible with Azoteq and focaltech. More info about touch capabilities can be found.New: Oct 2015, The new provide up to 800×600 resolution for sharper imagery, increased speed for faster data transfer and image/video loading, and larger memory capacity. This is welcome news, because it makes it possible to use the FT series also for 7″ displays.uses FT800. I could use this solution and try to glue the sensors and a Arduino on the main board. This can give relatively compact and thin hardware.
Maybe a bit overkill for my application. It’s not cheap, but compared to the cost for a LCD and shield used in the prototype, its not that bad. Two things I really like (except for great and fast graphics possibilities) is better concept for touch control and built-in support for showing jpg (saved space). There is also a SDcard reader and a accelerometer(!). The latter can be used to change display depending on orientation of the screen ? Gameduino is available at.I’m not terribly impressed by the screen quality of Gameduino2 when it comes to viewing angle.
According to the designer, he tried several screens that all had similar problems. It could help some.New:Dec2017: using FT81x is now in the works by James Bowman.Alternative version of the gdlib:: “ This is the first library that unifies different MCUs. The adjustments are simple depending on your choice, however we can help you solve your doubts and problems related to our community of forums”Another alternative is to examine a or MikroElektronika or with display. Also have FT800 with displays.Another solution is to use a basic board such as Atomsofts.
I believe it’s 3.3v only, with built-in backlight and a simple audio output, all on a very small PCB. Parts of the design is influenced by the Gameduino2. There are two versions according to AtomSoft: FT800 for resistive touch and FT801 for capacitive touch. Available on (no longer available, feb 2016)There are already people out there that has started using Gameduino2 with alternativ software such as.(2017 jan) I’ve experimented with FT810 with 7″ capacitive touch panel and Gameduino2 library.even shows PCB/schematics for a FT800 shield for Arduino.has several so-called Advanced Display Application Module based on FT800/801.RA8875RA8875 is a text/graphic mixed display with 2 layers TFT LCD controller. It is designed to meet the requirement of middle size TFT module up to 800×480 pixels with characters or 2D graphic application.

From their description: “The SmartGPU 2 is a powerful easy to use, intellectual property, graphics, audio, touchscreen and full datalogger processor embedded in a state-of-the-art ARM Cortex-M3 chip; this is mounted on a board with a touchscreen color LCD”. Guess that means they have their own graphics processor programmed into that Cortex chip.itron SMART TFT TU modules. Haven’t investigated further.Open Source 3.2″ TFT Smart Displayused i.e. The board is based on a PIC32 and a 3.2′ TFT with touchscreen (ILI9320 controller, using 16bits PMP). The software has two main parts. One that produces the 2D functions and a GUI with various widgets (buttons, check boxes, sliders etc)STM32I do also consider using a fast RISC processor such as stm32f4 to do all the work, including driving the display. The STM32F10xxx devices have an embedded FSMC (flexible static memory controller) which can be used together with the on-chip DMA controller to implement a direct drive for TFT-LCDs.

I want capacitive ones.
I’ve found:. from Buydisplay using a GSL1680 touch controller. from Buydisplay with FT5206 touch controller.
from Buydisplay. This might be compatible with Gameduino2/FT800. Uses a GSL1680 touch controller. Several at Newhaven. Example that uses FT5x06 touch controller.
It is expensive at $58.Separate touch panels (without the LCD screen) are also available such as or from BuyDisplay.It was relatively easy to write software driver for FT5xx6, some information can be found in my blog entry (Note that according to, the FT5x06 has firmware that are tailored to specific displays so I don’t know how easy it will be to buy a separate FT5206 and connect it to another LCD). More or less the same driver was also used for the FT5306 based standalone touch panel, ref. My blog entry.GSL1680 was tricker, but with help from a at forum.pjrc.com, I managed to.According to the datasheet, the FT801 chip supports FT5x06 or chips.
The (more in ) 4.3″ is available at Mouser for $10(?) (Note, April 2015: Current price at Mouser seems to be closer to $20 in single quantities) including controller. Combining this with a can be a cost effective solution at $20. Almost 1/3 of the Newhaven. Might be that the Newhaven is a better display though.Adafruit now have display using FT2606.is a link explaining the difference between capacitive and resistive touch.Panel, drivers, controllers – confused???I’ve been a bit confused about all various LCD panels, corresponding controllers etc. What the different parts actually do.
I’ve come to this (preliminary) explanation for myself (feel free to correct me in the comments field below):Bare LCD and driverThe bare lcd panel itself needs a driver. If it was just a raw LCD it would need hundreds of connections to control the pixel matrix. So the driver takes care of those signals. The interface to the driver is often referred to as 8 (or whatever) bits RGB with sync (VSYNC/HSYNC) and clock. An example of a bare lcd with driver is from NewHeaven. It is driven.
The connector to a LCD/driver combo is normally(?) a 0.5mm pitch 40-pin. Controlling the sync clock etc. Signals requires significant computing power and timing. An introduction can be read. Bare lcd and driver with 24-bit Parallel RGB InterfaceIn order to make it possible to use such a display(with driver) from i.e. An arduino, an additional controller is needed.
![Mcufriend_kbv Mcufriend_kbv](/uploads/1/2/5/3/125381112/915191162.jpg)
Examples are FT800/FT801 and RA8875. These controller generates the sync signals and RGB signals.
The arduino only has to write images or commands to the controller by parallel or serial interface.Combined LCD driver and controllerOr, maybe more often, there are many displays that has combined driver and controller. Example is that has a HX8369 controller. It comes with 0.5mm pitch 40-pin connector.
A Another example is that uses HX8352 and is soldered to a board with 40 pins header that is a bit easier to work with. The arduino communicates with the controllers through serial or parallel interface, but there are typically some differences in how they are programmed. Luckily, that supports many of the controllers (i.e. The 3.2″ from Coldtears), so you don’t have to write them from scratch.
To save some valuable memory it might be wise to remove the ones you do not need. Take a look at the UTFT source code to see what registers are used on the different controllers.
There are also some that have modified/reduced the library to speed things up such as this. There are also other separate code out there tailored to specific controllers. But I think UTFT is a good starting point for beginners. Coldtears LCD with 40 pin header Newhaven LCD with small 0.5mm pitch connectorFor beginners, I recommend buying a LCD with controller that is supported by the UTFT library. Make sure you buy one that has the controller pins available as a 40 pin connector at the end (not 0.5mm pitch!).
Makes it easier to connect to an arduino. A problem is that the LCDs I/O are often 3.3V. The LCD also needs power for LCD backlight. Luckily there exists so-called arduino breakout boards that contains the 5V to 3.3V conversion, backlight driver and often also a memory card slot. You then end up with a layer of Arduino(UNO/MEGA) - LCD breakout card - LCD with driver and controller.
Looks like a good intro to such a combo. From there, you might chose to buy only a bare display(with driver) and a separate controller board and wire it yourself. The adafruit and is a nice combo that has software and support. You then only need to connect wires from arduino to the controller board. Note that Adafruit calls the RA8875 board a “driver” board. In my terminology above, it is a “controller” board.
Might be that my terminology is not correct or maybe there are no strict definitions on what is controller and what is driverA relevant newbie thread about this can be found.
