sainsmart tft lcd sd tutorial made in china

SainSmart 3.2" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and mutilfunctional module for your project.The Screen include a controller SSD1289, it"s a support 8/16bit data interface , easy to drive by many MCU like STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is ADS7843 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

There is built-in SD card slot in the shield, so we can use it to upload images. But the images need to be converted RAW format first.You can use the tool here. SD libraries need to be preinstalled for displaying the image.

2.Put the SD libraries(ITDB02_Graph16、ITDB02_tinyFAT16 and tinyFAT) into the folder arduino-0023/libraries ,then upload the ino File/Examples/ITDB02_tinyFAT16/_240x320_Portrait.After reset, you can see the image in screen.

Note:The SD library only can be use in version arduino-00xx and the library only supports FAT16 fomatted SD card up to 2GB, so you need to fomat your SD card to FAT16. 4GB FAT16 fomatted SD card is tested not working. Long file names are not supported. Keep your file names compliant with 8.3 standard.

LCD-specified initialization 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

In this Arduino touch screen tutorial we will learn how to use TFT LCD Touch Screen with Arduino. You can watch the following video or read the written tutorial below.

For this tutorial I composed three examples. The first example is distance measurement using ultrasonic sensor. The output from the sensor, or the distance is printed on the screen and using the touch screen we can select the units, either centimeters or inches.

As an example I am using a 3.2” TFT Touch Screen in a combination with a TFT LCD Arduino Mega Shield. We need a shield because the TFT Touch screen works at 3.3V and the Arduino Mega outputs are 5 V. For the first example I have the HC-SR04 ultrasonic sensor, then for the second example an RGB LED with three resistors and a push button for the game example. Also I had to make a custom made pin header like this, by soldering pin headers and bend on of them so I could insert them in between the Arduino Board and the TFT Shield.

Here’s the circuit schematic. We will use the GND pin, the digital pins from 8 to 13, as well as the pin number 14. As the 5V pins are already used by the TFT Screen I will use the pin number 13 as VCC, by setting it right away high in the setup section of code.

I will use the UTFT and URTouch libraries made by Henning Karlsen. Here I would like to say thanks to him for the incredible work he has done. The libraries enable really easy use of the TFT Screens, and they work with many different TFT screens sizes, shields and controllers. You can download these libraries from his website, RinkyDinkElectronics.com and also find a lot of demo examples and detailed documentation of how to use them.

After we include the libraries we need to create UTFT and URTouch objects. The parameters of these objects depends on the model of the TFT Screen and Shield and these details can be also found in the documentation of the libraries.

So now I will explain how we can make the home screen of the program. With the setBackColor() function we need to set the background color of the text, black one in our case. Then we need to set the color to white, set the big font and using the print() function, we will print the string “Arduino TFT Tutorial” at the center of the screen and 10 pixels  down the Y – Axis of the screen. Next we will set the color to red and draw the red line below the text. After that we need to set the color back to white, and print the two other strings, “by HowToMechatronics.com” using the small font and “Select Example” using the big font.

Here’s that function which uses the ultrasonic sensor to calculate the distance and print the values with SevenSegNum font in green color, either in centimeters or inches. If you need more details how the ultrasonic sensor works you can check my particular tutorialfor that. Back in the loop section we can see what happens when we press the select unit buttons as well as the back button.

Ok next is the RGB LED Control example. If we press the second button, the drawLedControl() custom function will be called only once for drawing the graphic of that example and the setLedColor() custom function will be repeatedly called. In this function we use the touch screen to set the values of the 3 sliders from 0 to 255. With the if statements we confine the area of each slider and get the X value of the slider. So the values of the X coordinate of each slider are from 38 to 310 pixels and we need to map these values into values from 0 to 255 which will be used as a PWM signal for lighting up the LED. If you need more details how the RGB LED works you can check my particular tutorialfor that. The rest of the code in this custom function is for drawing the sliders. Back in the loop section we only have the back button which also turns off the LED when pressed.

In order the code to work and compile you will have to include an addition “.c” file in the same directory with the Arduino sketch. This file is for the third game example and it’s a bitmap of the bird. For more details how this part of the code work  you can check my particular tutorial. Here you can download that file:

I puzzled some hours with exactly the same hardware setup and made a quick & dirty, but successfully test script, combining LCD, Touch and SD Card Features.

At this stage, any panel would need to connect either to the HDMI or VGA port. Although there is a dedicated TFT connector on the board it"s not currently available for use. Foundation hopes to sell/promote a tested TFT once all tht other stuff is done!

Yes it"s ST7735 based like the Adafruit ones. I"ve got one with an Sainsmart Arduino UNO from China, comes with the ST7735 code for the Arduino by LadyAda.

I have started a project writing framebuffer drivers for small TFT LCDs. I have written a helper module that greatly simplifies writing such a driver. That is if the display is RGB565 and uses SPI. I have ordered two more modules that I will try and make drivers for:

This link states that there are two revisions of the waveshares board: 2.1 and 1.1 with the difference being that 2.1 works outside of the box, yet 1.1 would need extra drivers to work properly. It also states that clones of this product are often 1.1 so my best guess is that SainSmart is also based off 1.1

The overall customer support of SainSmart is technically incapable but are generally nice people to deal with. My package got stuck in customs and I had to pay an extra 25 euro, even tho I had explicitly stated that it should be sent from Germany, because I know shit like this happens.

Buying is a Type of Hunting Game. TFT LCD Display For Arduino Buying Guide is an Important Article as No Where There is Any Practical Guide. Practically we will use it as a base either as receiver or the central machinery for some stuffs around Internet of Things. Just for getting started with DIY electronics, we published some articles which possibly will help who are not exactly related to hardware but has more to do with software. Those articles mostly can be found by using the search option on this website, searching with Arduino will help to sort out.

We are avoiding the basic electronic displays like LED display, basic LCD display as we are NOT really related to so basic works of electronics. This website was never for so basic guides. There are hundreds of those basic websites for those guides. Hardware are time consuming to write, most importantly, testing the useless hardware hugely waste our space. It might dishearten our some readers, but basically we need a rapid shift towards our main niche. Ultimately we have to connect with the servers.

We have three options – TFT LCD Display, TFT LCD Touch Display and OLED display. You can check various places, monochrome OLEDs are the choice right now for manufacturing electronic units. OLEDs are hugely power saving but are far better than monochrome LCDs. There is not HUGE options in OLEDs for Arduino. Usage is very lesser in most situations where we will n

It"ll be a big help to those who are unsure of compiling the kernel, etcYes, and I guess that will include most of the Raspberry Pi userbase. Hopefully it will boost the use of these LCDs on the Pi. And plug&play displays like yours, make it even easier.

I tried to download the latest version •2013-02-09-wheezy-raspbian-2013-04-11-fbtft.zip - but its a dead link for me?Can you try again, I have moved the file to another server.

Also I read on Kamal"s blog ( http://www.whence.com/rpi/) that the sainsmart spi bus can be used up to 32mhz, but your driver defaults to 4mhz, the same as the adafruit unit. The adafruit display has an extra buffer chip inline so cannot be used at 32mhz, but the sainsmart does not so it can be run faster. My chinese display also does not have the extra buffer. Playing video back using mplayer seems a lot slower than that of Kamal"s kernel as well - have you tried it?

I selected the sainsmart 1.8" option as that is almost the same as my display however the RGB is swapped. Is there an option to change it?No, sorry it"s not.

spidevices: adafruit18fb spi0.1 32000kHz 8 bits mode=0x00Now lets load the driver telling it to display the transfer time for each frame sent (https://github.com/notro/fbtft/wiki/Debug):

Hi Notro - can we have the adafruit18fb (that brings the line to 2Mhz while sending commands) driver to support the rotate and bgr options as the sainsmart18fb please?

SainSmart 2.8" TFT LCD Display is a LCD touch screen module. It has 40pins interface and SD card and Flash reader design. It is a powerful and mutilfunctional module for your project.The Screen include a controller ILI9325, it"s a support 8/16bit data interface , easy to drive by many MCU like arduino families，STM32 ,AVR and 8051. It is designed with a touch controller in it . The touch IC is XPT2046 , and touch interface is included in the 40 pins breakout. It is the version of product only with touch screen and touch controller.

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.

OLEDs are hugely power saving but are far better than monochrome LCDs. There is not HUGE options in OLEDs for Arduino. Usage is very lesser in most situations where we will need a display. TFT LCD Touch Display doubles up as an input too. Without a computer, we can do the desired works in the way, suppose we did with the old color mobile phones. Smartphones are mostly a full OS driven, hence can not be compared. Most works which other displays can perform a TFT LCD Touch Display is able to perform.

There are several things to consider. First, it is basically meaningless to buy a bigger display at higher cost. Second, we do not need Mac like beautiful display. Third, connecting the display with various types of Arduino is not exactly very easy. Forth, even the official TFT LCD Touch Display library of Arduino is not fully complete, Adafruit has Open Source contribution. Fifth, there is a firmware of the whole thing, it is kind of “self dependent”. If a cheaper stuff’s library or firm is not compatible, no body’s father reverse engineer it.

We found two company’s name for 2.4″ TFT LCD Touch Displays – one is LuckSender, whose product sold around $4.99 in Ebay, but has a serious detailed pathetic, scary review by an Amazon customer. It probably has problem with compatibility.

Second company we found is named SainSmart. SainSmart is not exactly a small company, it has a modern website (we saw Affiliate link option in footer too – we are never interested to push anyone’s product to our readers), We noticed that, this company’s website has written :

But also we noticed that, SainSmart 3.2″ TFT LCD Display total unit for Arduino sells at Ebay at LESSER price than official website with free shipping. You can probably use the SainSmart’s forum for support. This display stuffs is probably less explored market.

For those who have lesser idea, this total stuff includes a board (shield) and a SD card slot too. $13.00 is not bad pricing for a TFT LCD Touch Display, although (as always) we think, the right price should be $1.30! We are kids, playing, we can not make money out of these, they should “sponsor” us. The market of Arduino is not exactly great right now unlike before, their monopoly is only in boards; Adafruit also not going great. Except display, the market is of China. Do not hurry, watch auctions and it is not improbable to get that brand’s at less than $10.00.

Spice up your Arduino project with a beautiful large touchscreen display shield with built in microSD card connection. This TFT display is big (7" diagonal) bright (14 white-LED backlight) and colorfu 800x480 pixels with individual pixel control. As a bonus, this display has a optional capacitive and resistive touch panel attached on screen by default.

The TFT display is a kind of LCD that is connected to each pixel using a transistor and it features low current consumption, high-quality, high-resolution and backlight. This 2.8-inch full color LCD has a narrow PCB display. The resolution is 320×280 pixels and it has a four-wire SPI interface and white backlight.
