The screen is 1.77" diagonal, with 160 x 128 pixel resolution. The TFT library interfaces with the screen"s controller through SPI when using the TFT library. Refer to the screen"s data sheet for complete details.

The Arduino TFT library extends the Adafruit GFX, and Adafruit ST7735 libraries that it is based on. The GFX library is responsible for the drawing routines, while the ST7735 library is specific to the screen on the Arduino screen. The Arduino specific additions were designed to work as similarly to the Processing API as possible.

The TFT library relies on the SPI library, which must be included in any sketch that uses the scree. If you wish to use the SD card, you need to include the SD library as well.

This is SainSmart MEGA2560  + 7 inch TFT LCD module with the TFT LCD shield kit For arduino enthusiasts.It includes one pcs of SainSmart MEGA2560 , 7 inch TFT LCD display and a TFT LCD shield for Arduino MEGA2560.This kit helps you to avoid complicated wiring processes and save you much time to accomplish your goal. You can feel free to enjoy the touch function and SD card function by using our codes.We will provided you the whole document including the example project of the kit. We will supply you the technical support after your purchase.

The MEGA2560 R3 also adds SDA and SCL pins next to the AREF. In addition, there are two new pins placed near the RESET pin. One is the IOREF that allow the shields to adapt to the voltage provided from the board. The other is a not connected and is reserved for future purposes. The MEGA2560 R3 works with all existing shields but can adapt to new shields which use these additional pins.

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 7 inch LCD including the touchscreen.

LCD-specificed intialization code is provided, so that you can save time to optimize power control register and gamma curves for best display performance. We have test the provided code, it gives the best display performanace

The above code works fine, the "Welcome" message is displayed on the screen, followed by the display of the "2.bmp" image as expected. The serial output prints:

Can you please tell me what could be wrong here ? I suspect the root = SD.open("/"); somehow affects the TFTscreen.loadImage(imageName); but I have no idea how.

I followed a number of different tutorials (e.g. this one https://mytectutor.com/micro-sd-card-module-with-arduino-and-tft-display/ ) but they are either using a ST7735 display which has an additional CS pin which my display does not have (could this be the problem?) or they don"t use an SD module.

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?
