tft lcd shield 2.4 with microsd interface brands

This is Sainsmart 2.4 inch TFT LCD module with the TFT LCD shield kit for arduino enthusiasts.It includes one piece of 2.4 inch TFT LCD display and a TFT LCD shield for Arduino MEGA2560 (R3).We will provided you the whole document including the example project of arduino due with the kit. We will supply you the technical support after your purchase.

Voltage type: 5v or 3v voltage input voltage,input is selectable. Because TFT can only work under 3.3 V voltage, so when the input voltage VIN is 5V, need through the 3.3 V voltage regulator IC step down to 3.3V , when the input voltage of 3.3 V, you need to use the zero resistance make J2 short , is equivalent to not through the voltage regulator IC for module and power supply directly.(Click here)

It is 100% compatible with the normal MCU like ARM AVR PIC and 8051,especially on arduino family such as arduino due and arduino mega2560(R3).The module uses the LCD controller Chip SSD1963 with 5 inch LCD including the touchscreen.

The shield defines that all the the data transmit ports are PC1-PC8 and PC12-PC19,the controll pins are PD0-PD3.The perfect design could realize that the data transmits in high speed.The SPI interface is designed in the ISP header of arduino due so that the SPI transfer with DMA could be achieved in high speed with no drag.

I just purchased Seeed"s TFT Touch Shield 2.0 for Arduino, but I cannot seem to figure out how to access the SD card while maintaining the ability to draw to the screen. The tutorials and documentation are quite insubstantial (for me), and most questions on the product site seem to be directed to the same wiki page, which doesn"t explain anything about the SD interface, other than what example file draws bitmaps from the card.

I"ve used the SD interface with the Ethernet Shield before, but it"s been a long time since then, so I can"t quite remember the ins and outs. From my old code, it seems that, for normal usage of the SD library, you simply do:

What I assume is happening is that pins 11 through 13 are set to input for some SPI-related reason, the TFT chip select "enabled" mode is set to HIGH, and then the screen is subsequently enabled. Serial moniter is started, followed by SPI, and then the TFT. After those things happen, it does something unknown to me, starts the card, and then uses the standard card initialization method. It finishes up by preparing to draw the bitmaps and sends this "command 0x2c", which is used frequently in the underlying libraries to "start to write to display ram".

The problem is that I have tried initializing the TFT and SD card using this code, and then attempted to draw graphics as shown in my second example, but this did not work. I need to be able to read bytes from the SD card, and then be able to draw simple graphics on-screen, and repeat.

So my question is: Is anyone who has used this shield before or has experience with this able to explain how one should go about writing the code to allow usage of both the SD card and screen or how the initialization and SPI processes work to make this possible?

That means you can use digital pins 2, 3 and analog 4 and 5. Pin 12 is available if not using the microSD Works with any Arduino "328 , 5V compatible! Use with 3.3V or 5V logic Onboard 3.3V 300mA LDO regulator 4 white LED backlight. On by default but you can connect the transistor to a digital pin for backlight control 4-wire resistive touchscreen

The Shield is fully assembled, tested and ready to go. No wiring, no soldering! Simply plug it in and load up our library – you will have it running in under 10 minutes! Works best with any classic (UNO/Duemilanove/Diecimila). This shield does NOT work with the Mega but it is going to be half the speed of the Uno-type boards because of the way the Mega rearranges all the pins (there is no way to get around this!) This shield is not Leonardo-compatible.

Spice up your project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (2.4″ diagonal) bright (4 white-LED backlight) and colorful (18-bit 262,000 different shades)! 240×320 pixels with individual pixel control. It has way more resolution than a black and white 128×64 display. As a bonus, this display has a resistive touchscreen attached to it already, so you can detect finger presses anywhere on the screen.

Add some jazz & pizzazz to your project with a color touchscreen LCD. This TFT display is 2.4″ diagonal with a bright (4 white-LED) backlight and it"s colorful! 240×320 pixels with individual RGB pixel control, this has way more resolution than a black and white 128×64 display.

If you need a larger touchscreen, check out the 2.8″ diagonal or 3.5″ diagonal TFT breakouts. For a smaller display, see our non-touch 2.2″ or 1.8″ or 1.44″ diagonal TFTs

This display has a controller built into it with RAM buffering, so that almost no work is done by the microcontroller. The display can be used in two modes: 8-bit or SPI. For 8-bit mode, you"ll need 8 digital data lines and 4 or 5 digital control lines to read and write to the display (12 lines total). SPI mode requires only 5 pins total (SPI data in, data out, clock, select, and d/c) but is slower than 8-bit mode.

Of course, we wouldn"t just leave you with a datasheet and a “good luck!”. For 8-bit interface fans we"ve written a full open source graphics library that can draw pixels, lines, rectangles, circles, text, and more. For SPI users, we have a library as well, its separate from the 8-bit library since both versions are heavily optimized. For resistive touch, we also have a touch screen library that detects x, y and z (pressure) and example code to demonstrate all of it. Check out our tutorial for wiring diagrams, schematics, and a walkthough on this display.

The DMG32240C024_03WTR - 2.4 inch 320x240 UART TFT LCD Display Resistive Touch, 16MB Flash Buzzer SD interfaceis developed by DWIN. The NOR Flash memory in the display is available to store the user database.

The LCD is integrated with a running DGUS II system, a GUI (Graphical User Interface) development software. The pre-installed UI user interface development software can be used to develop your own design and customised features like buttons, text display, graph and slider etc. The T5L1 DWIN development software is a human-machine interface dedicated to ASIC designed by DWIN Technology for AIoT application applications. This software is based on a T5L chip that is a low-power, cost-effective dual-core 8051 processor.

Answer: Yes of course, after download modbus kernel, DWIN screen will support modbus protocol.(some module not support update modbus kernel, please check with DWIN service before buying)

Answer: The DWIN smart LCD modules / smart screens / smart displays can be used for Android Touch Panel, HMI Touch Panel, Smart LCD Display Module, Smart Touch LCD Module, Smart Touch Screen Display, Industrial Touch LCD Display, PLC Display Screen, Serial Port LCD Display, STM32 MCU Displays etc.
