arduino 5 tft lcd touch screen shield ra8875 manufacturer

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (5" diagonal) bright (12 white-LED backlight) and colorfu 480x272 pixels with individual pixel control. As a bonus, this display has a optional resistive touch panel attached on screen by default.
The shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library - you"ll have it running in under 10 minutes! Works best with any classic Arduino (UNO/Due/Mega 2560).
This display shield has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. You can connect more sensors, buttons and LEDs.
Of course, we wouldn"t just leave you with a datasheet and a "good luck!" - we"ve written a full open source graphics library at the bottom of this page that can draw pixels, lines, rectangles, circles and text. We also have a touch screen library that detects x,y and z (pressure) and example code to demonstrate all of it. The code is written for Arduino but can be easily ported to your favorite microcontroller!
For 5 inch screen,the high current is needed.But the current of arduino uno or arduino mega board is low, an external 5V power supply is needed. Refer to the image shows the external power supply position on shield ER-AS-RA8875.
If you"ve had a lot of Arduino DUEs go through your hands (or if you are just unlucky), chances are you’ve come across at least one that does not start-up properly.The symptom is simple: you power up the Arduino but it doesn’t appear to “boot”. Your code simply doesn"t start running.You might have noticed that resetting the board (by pressing the reset button) causes the board to start-up normally.The fix is simple,here is the solution.

Now, I am running the sample touch application (Libraries+Examples for 4-wire SPI 7"Capacitive Touch Shield) taken from here https://www.buydisplay.com/default/serial-spi-arduino-7-inch-tft-lcd-touch-shield-ra8875-for-mega-due-uno, but touch screen is not working.

Arduinos cannot drive a display directly. Small TFT screens often include the driver chip on them in the form of a Chip On Glass (CoG). That can"t be done with the larger screens due to the sheer amount of memory needed to store the frame buffer. So an external chip has to be used, or a microcontroller with built in TFT interface.
Note that even with an SSD1963 (or equivalent - see the ones BuyDisplay sell are based on the RA8875) interfacing the Arduino to the TFT screen results will most likely be somewhat disappointing. Especially if you are interfacing using SPI or I2C which will create a bottleneck. Best is to interface with a 16-bit "8080" interface (16 data bits, read, write, chip select, reset and D/C), however that takes a lot of IO pins, and ideally a proper parallel interface to drive it quickly. And you want a lot of RAM for manipulating the data you want to display...

Have you gazed longingly at large TFT displays - you know what I"m talking about here, 4", 5" or 7" TFTs with up to 800x480 pixels. Then you look at your Arduino. You love your Arduino (you really do!) but there"s no way it can control a display like that, one that requires 60Hz refresh and 4 MHz pixel clocking. Heck, it doesn"t even have enough pins. I suppose you could move to ARM core processors with TTL display drivers built in but you"ve already got all these shields working and anyways you like small micros you"ve got.
What if I told you there was a driver chip that could fulfill those longings? A chip that can control up 800x480 displays, and heck, a resistive touchscreen as well. All you need to give up is 5 or so SPI pins. Would you even believe me? Well, sit down because this product may shock you.
The RA8875 is a powerful TFT driver chip. It is a perfect match for any chip that wants to draw on a big TFT screen but doesn"t quite have the oomph (whether it be hardware or speed). Inside is 768KB of RAM, so it can buffer the display (and depending on the screen size also have double overlaying). The interface is SPI with a very basic register read/write method of communication (no strange and convoluted packets). The chip has a range of hardware-accelerated shapes such as lines, rectangles, triangles, ellipses, built in and round-rects. There is also a built in English/European font set (see the datasheet section 7-4-1 for the font table) This makes it possible to draw fast even over SPI.
The RA8875 can also handle standard 4-wire resistive touchscreens over the same SPI interface to save you pins. There"s an IRQ pin that you can use to help manage touch interrupts. The touchscreen handler isn"t the most precise driver we"ve used, so we broke out the X/Y pins so 11:54)

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).

Hi i bought buydisplay 9" display ra8875 and arduino shell. i m sending the images to tft via sd card is very slow and i want to try flash chip, backside the screen there is a an empty flash area. i bought 25q128fv flash chip for tft not soldered and have a programmer for 25q128fv. im searching a simple example for use that flash to use only view images to screen with uno or stm32f103cb (maple mini) are there any friends have an idea??
yes but they are sending me 8051 mcu keil v4 project. factory producing tft screen and slot for flash chip but any example how to use flash nowhere :(
Apart the infamous bugs, the RA885 chip it"s the only one that let you drive large displays (max 800x480) with touch screen and using very few processor resources.
I am using "5 inch TFT LCD Module 800x480 Display w/Controller I2C Serial SPI" in one of my project. Communication interface is 4 wire SPI. I have ordered the display with 4 wire SPI mode, after receiving the display i have not made any changes to the hadrware. Just soldered one connector for SPI connectivity with microcontroller. Display is 3.3V.
I have initialized the TFT and SPI communication. But, i am unable to see any thing on the TFT display. When i probed SCLK and chip select(CS) i could see signals in oscilloscope. On MISO able to see signals but little distorted. But MOSI is completely high.
This is indeed the wrong forum for your SAM21 question! You"re not even using anything that looks like any of the code published by PJRC or others for Teensy boards. It"s completely different code (without the functions like TFT_CmdWrite shown).
