tftm070-5 7 tft display in stock
ER-TFTM070-5 is 800x480 dots 7" color tft lcd module display with RA8875 controller board,superior display quality and easily controlled by MCU such as 8051, PIC, AVR, ARDUINO, and ARM .It can be used in any embedded systems,industrial device,security and hand-held equipment which requires display in high quality and colorful image.
Of course, we wouldn"t just leave you with a datasheet and a "good luck!".Here is the link for7" TFT capacitive 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.

Hi Vitaliy, I"ve migrated from the 4.3 to the 5" display, but both are the 480 x 272 pixels formats. As I created the SW, I did try to keep in mind the larger display with the 800 x 480 pixel layout, but I had no way to test.
For the capacitive touch screen, on the other hand, you might be more on your own. I mention on the Components - RA8875 page that I don"t have any support for that simply due to the fact that for my project needs I could not give up the extra pins needed for the I2C interface to support the cap-sense controller (so I didn"t buy one). I tried searching the mbed site but couldn"t find any work of others that might fill that gap.
2017 Update: This is an old post, but in the summer of 2016 I picked up a 7" display, 800x480, and with the capacitive touch panel. I"ve integrated the touch driver into the base code, so that it [more or less] transparently supports either the resistive or the capacitive. Of course, only the CAP sense version handles multi-touch.
Thanks for the answer, I"ll continue to investigate. I display ER-TFTM070-5 http://www.buydisplay.com/default/7-inch-lcd-module-capacitive-touch-screen-panel-i2c-spi-serial, configuration 4-wire SPI + Resistive Touch Screen.
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 spent considerable time trying to solve what I thought was a wiring/power problem to the display when it was a bad SD card. When the I removed the card and power-cycled the rig the Nextion display came up fine with a demo program that was already loaded. So my recommendation is for the initial power up of the display don’t insert the SD card. That way you can be sure that you have it wired up ok before you start messing with SD cards.
You may get a message on the display that the load failed because there is more than one .tft file on the SD card. This can happen even when you look and you see only one file.
You need to be sure to enable viewing of hidden files in file explorer (Windows) or finder (on a Mac)… There’s probably one hiding there with the .tft suffix that you need to delete. I don’t think either operating system will show hidden files by default. The same goes for Linux.
Power up the display before you start making holes and check the orientation of the display and that the screen is functioning correctly. As with the 16×2 display, it is possible to install the display upside down by mistake! Given it is not symmetric (there is a wider bar to the right hand side of the display) care is needed! The inner silver line on the screen defines the touch sensitive boundary. Cut your hole so that the screen fits so the line is just visible around the outside edge.
Dimensions of Nextion displays can be found for this zone on the itead website. Click on your display and near the bottom of the page you will find a link to the screen dimensions.
was not planning to update this so soon, but it is cold and windy outside so i updated for Two way communication . multiple displays windows and multiple graph options. now divided into 3 quadrants the top bar for meter and informational display - 6 panel option, left hand quadrant for information and MQTT switch control ( ie thermostatic control)- 4 panels option . And Right hand Quadrant for graphing differing inputs, ie solar/grid production comparison, outside temperature, solar and Diverter usage. also 4 different panels
for example the displayed Thermostat if you touch the left hand side of the meter the temperature goes down if you touch the right hand side the temperature goes up they will send a command via mqtt to the thermostatic relay and when the thermostatic relay response to the sent string the green number will display the change in preset temperature
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.
