Strong anti-interference ability. The module uses the driving scheme of CPLD + SDRAM, which far more superior than SSD1963 and RA8875. Solve the problem of bad immunity, death and white screen from SSD1963.

Good simplicity. Not need an initializer, what have to do is reset can start work. You can use 5 register command to control it. Greatly simplifies the program code, reduce degree of difficulty of debugging the program and error probability.

Fast speed. The respond speed of W/R cycle can be up to 200ns. The fastest full screen refresh rate is 13 frames. 8M SDRAM correspond to 8 pages display cache. The display registers and RW one is set independently. Display page and RW page also can be in which data can be written in the background. Just using one command to change screenful display data instantly. Far more superior than RA8875.

Good display effect. TFT drive timing and circuit design have been optimized to ensure accurate color reduction, display a stable, eliminate flicker or channeling color and offers LED backlight driver, you can adjust the brightness from 0 (off) to 16 (fully open).

that 7 inch display uses the RA8875, you can see that on the specification of the display. The 320x240 uses the ili9341 (that is why the name of the library is ili9341).

I found two libraries, I don"t think they will be optimized for the Teensy. Test this one https://github.com/sumotoy/RA8875 and this one https://github.com/adafruit/Adafruit_RA8875

The only 7 inch I"ve seen around are RA8875 (4 wires plus 3 for Touch and int) or SED (16 bit plus several wires more, together with I2C for the capacitive touch will leave you with almost no port left).

In summary.. the display will work, and is most likely that the capacitive IC will also work read this (https://github.com/sumotoy/RA8875/wiki) so you are aware of the library limitations.....

Based on your replies, the 7 inch LCD we found "should" work, uses RA8875 controller, and there are at least (2) libraries which "should" work, but may need

The SD holder mounted on buydisplay will not work, you can get working at incredible low SPI speed but sincerily I never get really working, they mounted capacitors, series resistors and prolly pullups.

To get an SD work you should isolate the RA8875 with the circuit I described in github wiki, get a quality SD holder (like the one mounted in the PJRC audio board) and mount very near Teensy (or you can use the SD card holder homemade adaptor described here (https://forum.pjrc.com/threads/16758-Teensy-3-MicroSD-guide?p=56149&viewfull=1#post56149).

But you have to isolate the RA8875 wiith a small circuit described here (https://github.com/sumotoy/RA8875/wiki/Fix-compatibility-with-other-SPI-devices) or it will not work!

Just a note, the RA8875 it"s not the best chip to send images, it"s extremely fast driving his accellerated geometric primitives, internal fonts, etc, etc. but receiving pixels it"s a slow business.

The best way I found it"s send an entire line, better than one pixel a time but still not efficent, I"m actually cannot find another way in datasheet, so don"t expect to read large images in less a second on a 800x480 display, it will take not less than 3 secs using the max SPI speed and a SDholder very near to Teensy with a high speed SD card.

The RA8875 has a separate SPI that can drive internally (very fast and using DMA) a SPI flash chip, it looks promising but it"s a bit complicated since you have to program SPI Flash chip separately, I will test this option in near future since the library already support that.

The library can use any permitted Teensy 3.0,3.1 and LC configuration, it"s compatible with the PJRC Audio Card and it"s SPI Transaction compatible, it works well with the new SD optimized for Teensy library by Paul. Datasheet on hand the RA8875 has a SPI limit of 12Mhz but (after weeks of testing) actually I"m driving it at 22Mhz without problems by modulating SPI speed on some register so when you work with that SPI speed you always have to use short cables and good decoupling, it can work with a good quality breadboard but use always short cables and be sure contact it"s good.

The RA8875 library already support it internally, don"t need an external FT5206 library, just go to RA8875UserSettings.h file and uncomment #define USE_FT5206_TOUCH.

Note that ER-TFTM070-5 uses a lot of current for backlight, you will need a separate supply! In that case you need to wire the RST pin as well (any free Teensy pin should work).

Some user configured ER-TFTM070-5 at 5V and they are able to drive it by 5v from Teensy but you can easily get garbage on screen because the voltage should be at list 4.8V and stable, not less.

The reason it"s simple, the RA8875 chip it"s like a microcontroller, you send a command and you have to wait it finish it so you are forced to polling it"s busy port or use an INT for that.

The RA8875 it"s a great controller, actually it"s the only one that uses very tiny microcontroller resources (you can use a 800x480 16bit color display with 5 concurrent touches, actually impossible with any other display).

If you are cool with 3-4 sec loding time, you ca use it, or better try the internal SPI flash method that I never tested but should work, on-paper it can transfer images by using internal RA8875 DMA very fast.

C:\Program Files (x86)\Arduino\libraries\RA8875-0.70\RA8875.cpp: In member function "void RA8875::_charWriteR(char, uint8_t, uint8_t, uint8_t, uint16_t, uint16_t)":

C:\Program Files (x86)\Arduino\libraries\RA8875-0.70\RA8875.cpp: In member function "void RA8875::_drawChar_unc(int16_t, int16_t, int16_t, const uint8_t*, uint16_t, uint16_t)":

About the powerup sequence... It"s normal that you power up the LCD first! The Teensy has to be able to initialize the display when it power ups but LCD it"s not on, Teensy will start to initialize...nothing.

I strongly suggest (in that case) to use always the RST pin, the RA8875 get ready sooner that Teensy and Teensy it"s still able to reset it and initialize correctly.

About 7" supply (and why it needs a separate supply), the 7" model has a backlight that suck a lot of current, too much for any USB. I have a PC that is able to give more than 500mA on USB but I have noticed some garbage on screen from time to time, this was caused by the supply voltage that was not stable and modulate from 4.90V to 4.45V, setting brightness to 150 stabilized to 4.80V.

On Eastrising boards (and Adafruit) the backlight it"s handled internally by RA8875 using an internal PWM generator and this is why (if RA8875 it"s not correctly inited) it appears completely black with no apparent life, in contrast with other displays where you get the backlight on (at list) but thanks to this you can setup your display to consume less power by adding brightness(nnn) after initialization, I was able to supply this large 7" beast with a battery by using 150, 120 value.

This tells library to include the FT5206 routines that handles capacitive touch screen. The 7" screen uses an external FT5206 chip as capacitive touch but RA8875 handles only resistive touch internally so this command enables the correct routines.

The RA8875UserSettings.h contains a lot user defines, this is necessary for tune the library in relations your needs. You will notice that once enabled #define USE_FT5206_TOUCH many examples will give you an error caused by the FT5206 routines that needs the wire.h to be included.

A really simple test it"s put a brightness(150) command just after begin in setup, this will cut a lot the current of the backlight and stabilize the voltage (that don"t continue drop down), this is useful to check if the Power Supply affects the code because undervoltages and drops.

The example shows the screen that react from 1 to 5 concurrent touches (by a different colour for every concurrent touch) and detect also some other parameters like gesture (all hardware detected by Touch IC)

I"m pretty sure that you don"t have any capacitive touch actually present, maybe it"s a resistive one but can be a 7" display without any touch capabilities!

It"s not easy to use the flash chip on RA8875 since you need to program flash BEFORE solder on RA board, once soldered you can use the library functions to access it.

The RA8875 access the flash chip from an internal separate SPI trough his DMA internal routines but there"s no way to "see" the chip or it"s content from outside once soldered.

I wroted already a note to Eastrising (about this and the nonsense capacitors in the SPI lines) but never respond, Buydisplay are more gentle but actually the just sell and not produce the board.

In theory you can prepare some images in the SD card and when you are sure you can transfer to the SPI flash but the RA8875 access the images on flash by using an offset and image lenght so I"m not sure the images are tranferred from SD to Flash have this format.

What about try to mount a DIP to SMD adaptor on the display? If you mount your Flash chip on a DIP adapter you will able to program externally then mount on display by just plug it. I"m not a great SMD solder but I"m sure there"s a way to do that.

Using I2C flash for images? I2C it"s really slow! the display works at 22Mhz and you are plan to use max 400Khz from I2C device, I don"t think it"s a good idea.

Maybe better use a SPI Flash (and follow the RA8875 SPI isolation described in the wiki to avoid SPI collisions), I don"t know how much fast is the SPI flash in reading, for sure there"s some expert here that can help in this.

The RA8875 based displays are just regular LCD with a controller a bit more sofisticated than usual, the RA chip has hardware accellerated graphic primitives, some internal font stored inside, a RAM buffer for the entire screen (plus some more bytes for extra fonts and patterns) and a dedicated SPI for external ROM font and a Flash Chip, quite a lot but not so powerful as the 4D system that can really store images, maybe consider one of those (expensive) displays for your application?

You want to store images in the display.... Where? The display has a buffer RAM and at 800x480 it"s limited at 8bit and the Flash memory on the LCD it"s read only since it stays in another SPI dedicated bus, you cannot send images to flash trough RA.

I have found that older thread. It is matching what I am trying to do... I have ordered the same display and want to used it with Teensy 3.2 and Audio. So, my problem is, that the PINs that are used for that TFT are allready used for Audio... What can I do?

The Audio shield uses 18/A4 and 19/A5 for the i2c bus, which allows other devices to be connected to the bus, assuming they have a different i2c bus than the devices already in use. The Audio board uses addresses 0x0A and 0x1A.

The Audio shield also uses the SPI bus, but you have to use two alternate pins (you have to use pin 7 instead of pin 11, and pin 14/A0 instead of 13). In addition, you need to change the CS pin (chip select) to be a pin that isn"t used by anything else. Some devices need to use the special hardware chip select pins, and you would need to use 20/A6 or 21/A7 if the display has the special optimizations.

In addition, most of the displays have a second pin (D/C) that flips between data/command, and this pin also must be a special CS pin. In the displays I"ve looked at (ST7753, SSD1351), there is a reset pin, but that pin does not have to be one of the special pins.

This means of the special pins, you have only pins 20/A6 and 21/A7 (pins 9, 11, 13, 22, and 23 are used for i2s; pin 15/A1 has resistors/etc. for soldering a volume switch to the board).

The only problem I"ve found with the 7" display is the pixels are not square, so when you draw a circle it is not completely round. Makes displaying gauges not look right.

its me again... So display is working very nice.... :-) But when I am trying to add some code (what is in /* */ in setup() ) for Audio-shield the display stopps working... So what is going wrong?

In the meanwhile I have tryed some things... and found out, that TFT- problems starts when SD- Card is in the Audio-shield-slot... w/o any changes in code...

And so I read some postings to that issue and found that there might be a problem with RA8875- SPI and other devices on the same line. So TFT is ussing PIN7 on teensy for MOSI, PIN8 for MISO and PIN14 for CLK.

Audio Board uses (?) PIN7 for MOSI too and PIN12 for MISO... PIN11 could also be used as MOSI, but is allready used from Audio-Board... so what can I do? Would it be better to use PIN11 for TFT? But what should I do with that connection to Audio-Board?

Or if you have a Teensy 3.5, 3.6 or LC, there are alternate SPI ports that you could use. You would have to modify the library to use SPI1 or SPI2 instead of SPI.

In this article, you will learn how to use TFT LCDs by Arduino boards. From basic commands to professional designs and technics are all explained here.

In electronic’s projects, creating an interface between user and system is very important. This interface could be created by displaying useful data, a menu, and ease of access. A beautiful design is also very important.

There are several components to achieve this. LEDs,  7-segments, Character and Graphic displays, and full-color TFT LCDs. The right component for your projects depends on the amount of data to be displayed, type of user interaction, and processor capacity.

TFT LCD is a variant of a liquid-crystal display (LCD) that uses thin-film-transistor (TFT) technology to improve image qualities such as addressability and contrast. A TFT LCD is an active matrix LCD, in contrast to passive matrix LCDs or simple, direct-driven LCDs with a few segments.

In Arduino-based projects, the processor frequency is low. So it is not possible to display complex, high definition images and high-speed motions. Therefore, full-color TFT LCDs can only be used to display simple data and commands.

In this article, we have used libraries and advanced technics to display data, charts, menu, etc. with a professional design. This can move your project presentation to a higher level.

Size of displays affects your project parameters. Bigger Display is not always better. if you want to display high-resolution images and signs, you should choose a big size display with higher resolution. But it decreases the speed of your processing, needs more space and also needs more current to run.

After choosing the right display, It’s time to choose the right controller. If you want to display characters, tests, numbers and static images and the speed of display is not important, the Atmega328 Arduino boards (such as Arduino UNO) are a proper choice. If the size of your code is big, The UNO board may not be enough. You can use Arduino Mega2560 instead. And if you want to show high resolution images and motions with high speed, you should use the ARM core Arduino boards such as Arduino DUE.

In electronics/computer hardware a display driver is usually a semiconductor integrated circuit (but may alternatively comprise a state machine made of discrete logic and other components) which provides an interface function between a microprocessor, microcontroller, ASIC or general-purpose peripheral interface and a particular type of display device, e.g. LCD, LED, OLED, ePaper, CRT, Vacuum fluorescent or Nixie.

The display driver will typically accept commands and data using an industry-standard general-purpose serial or parallel interface, such as TTL, CMOS, RS232, SPI, I2C, etc. and generate signals with suitable voltage, current, timing and demultiplexing to make the display show the desired text or image.

The LCDs manufacturers use different drivers in their products. Some of them are more popular and some of them are very unknown. To run your display easily, you should use Arduino LCDs libraries and add them to your code. Otherwise running the display may be very difficult. There are many free libraries you can find on the internet but the important point about the libraries is their compatibility with the LCD’s driver. The driver of your LCD must be known by your library. In this article, we use the Adafruit GFX library and MCUFRIEND KBV library and example codes. You can download them from the following links.

By these two functions, You can find out the resolution of the display. Just add them to the code and put the outputs in a uint16_t variable. Then read it from the Serial port by Serial.println(); . First add Serial.begin(9600); in setup().

First you should convert your image to hex code. Download the software from the following link. if you don’t want to change the settings of the software, you must invert the color of the image and make the image horizontally mirrored and rotate it 90 degrees counterclockwise. Now add it to the software and convert it. Open the exported file and copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are sizes of image. you can change the color of the image in the last input.

Upload your image and download the converted file that the UTFT libraries can process. Now copy the hex code to Arduino IDE. x and y are locations of the image. sx and sy are size of the image.

In this template, We just used a string and 8 filled circles that change their colors in order. To draw circles around a static point ,You can use sin();  and cos(); functions. you should define the PI number . To change colors, you can use color565(); function and replace your RGB code.

In this template, We converted a .jpg image to .c file and added to the code, wrote a string and used the fade code to display. Then we used scroll code to move the screen left. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We used sin(); and cos(); functions to draw Arcs with our desired thickness and displayed number by text printing function. Then we converted an image to hex code and added them to the code and displayed the image by bitmap function. Then we used draw lines function to change the style of the image. Download the .h file and add it to the folder of the Arduino sketch.

In this template, We created a function which accepts numbers as input and displays them as a pie chart. We just use draw arc and filled circle functions.

while (a < b) { Serial.println(a); j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 255, 255)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

while (b < a) { j = 80 * (sin(PI * a / 2000)); i = 80 * (cos(PI * a / 2000)); j2 = 50 * (sin(PI * a / 2000)); i2 = 50 * (cos(PI * a / 2000)); tft.drawLine(i2 + 235, j2 + 169, i + 235, j + 169, tft.color565(0, 0, 0)); tft.fillRect(200, 153, 75, 33, 0x0000); tft.setTextSize(3); tft.setTextColor(0xffff); if ((a/20)>99)

In this template, We display simple images one after each other very fast by bitmap function. So you can make your animation by this trick.  Download the .h file and add it to folder of the Arduino sketch.

In this template, We just display some images by RGBbitmap and bitmap functions. Just make a code for touchscreen and use this template.  Download the .h file and add it to folder of the Arduino sketch.

The speed of playing all the GIF files are edited and we made them faster or slower for better understanding. The speed of motions depends on the speed of your processor or type of code or size and thickness of elements in the code.

I am using a 5inch Buydisplay RA8875 TFT ( 5"TFT LCD Display Capacitive Touchscreen w/RA8875 Controller 800x480 ) with buydisplay RA8875 shield and Arduino Mega

I am burning the example code as given in GitHub - schuppeste/RA8875Ada-BTE: Adafruit 1.0.0 old Library with BTE Extension for SPI-Flash to print the image with few very basic modifications. Following is the code:
