This is SainSmart UNO R3 and 2.8 inch TFT LCD module with the TFT LCD shield kit For arduino enthusiasts.It includes one pcs of sainsmart UNO R3, one pcs of 2.8 inch TFT LCD display and a TFT LCD shield. We will provided you the whole document including the example project of arduino UNO(R3) with the kit. We will supply you the technical support after your purchase.

The SainSmart Uno R3 is a microcontroller board based on the ATmega328 . It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with a AC-to-DC adapter or battery to get started.

1.0 pinout: added SDA and SCL pins that are near to the AREF pin and two other new pins placed near to the RESET pin, the IOREF that allow the shields to adapt to the voltage provided from the board. In future, shields will be compatible with both the board that uses the AVR, which operates with 5V and with the Sainsmart Due that operates with 3.3V. The second one is a not connected pin, that is reserved for future purposes.

This is SainSmart TFT LCD Extend shield for UNO(R3) .Using this shield can help you out of the bothers to use other cables. You just need to plug the module to arduino UNO(R3) through this shield.

If you connect the touch screen LCD with UNO R3, the touch screen function will be useless . If you want to use the touch function, please connect the LCD with Mega2560 (R3) or Due (R3).

2.The LCD is compatible for arduino family,but the Shield is just for the arduino UNO R3. If you need the LCD Extend shield for other arduinos, you need another shield which is also provided from our store.

I have been scouring the web to find all different bits of information for the Sainsmart 2.8 inch touch display with no avail on instructions on how to actually make it work.

I assumed that being it has a compatible 40 pin header that all I needed to do was put a 40 pin cable on it and install software and the os would pick up the display by default.

So I contacted them and they sent me out the documentation etc. As I read all the documentation there was not one mention of how to get the PI to recognize the display. So I contacted them again and the response was to try element14.com. I went there and again no avail.

I am hoping that this is the last stop and that someone might have instructions on how to get the pi to recognize the display. Currently when hooked up the screen lights up, but that is about it, no output what so ever. The only output is what is going through the hdmi port to the tv.

All the accessories listed below tier pricing need to pay.We won"t deliver until you select. Power adaptor should be 5V/2000mA in output and center pin for positive voltage and the outer shield for negative voltage .The temperature for controller RTD2660 would increase during working.That"s normal phenomenon,not quality problem.

2.8inch RPi LCD (A) and 3.2inch RPi LCD (B) are compatible with each other (the only differences are screen size and keys count), and can be mutually substituted in most cases.

Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.

However, for the first testing, you may want to use our image directly (if provided).Why the LCD still doesn"t work with the Waveshare provided image?Make sure the hardware connection is correct and connects fine.

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.Which power supply should I use?It is recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC"s USB port might have not enough power.

CONS: low refresh rate & resolution, supports Raspberry Pi only, requires Raspberry Pi 40PIN GPIO (the SPI bus), poor compatibility with Raspberry Pi system.

PROS: high refresh rate, multiple resolution support, multiple devices support, leaves the Raspberry Pi 40PIN GPIO free, better compatibility with Raspberry Pi system.

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They"re usually some poor copies of our early hardware revisions, and comes with none support service.

I was torn in deciding how many stars to give this. For starters, I must mention that I own 5 of these things -- 3 of the Mega2560R3 kits and 2 of the Due kits. This review is the collective findings of both varieties.I"m going to start with a key problem and warning that everyone who has bought or is thinking of buying these things should read:WARNING: The configuration jumpers on ALL five of the units I"ve received were jumpered incorrectly from the factory. The Mega2560R3 boards had both the 5v and 3.3v selection jumpers soldered, meaning if you plug it in as-is, you"ll short out the two power supplies. Their pictures of the board all show only the 3.3v jumpers selected, which is correct, but the three Mega boards I received, the LCD shield boards were jumpered wrong with both voltages selected. The two Due boards were also jumpered wrong. However, they didn"t have both jumper sets applied, they only had the 5v jumpers applied. Even if the LCD could stand 5v (and would be OK since all of its I/O pins are outputs from the processor), jumping it wrong would also mean powering the touchscreen chip from 5v causing the inputs to the Due processor to see 5v, and the input pins of the SAM micro are NOT 5v tolerant.This problem is likely why some of the other reviewers mentioned processors and things getting hot. So step one, regardless of which board set you get, check your jumpers! The LCD should be configured for 3.3v and only one voltage selection jumper should be applied per option so you don"t short out both supply voltages.Of the five units I received, one LCD screen glass was cracked. It still functions, but the crack renders the touchscreen portion somewhat unusable. Another LCD screen apparently has a panel that was wired backwards (between the driver chip and the LCD panel itself). I thought at first it was defective as the screen had the appearance of the old SSAVI style cable scrambling technique with a "torn" picture. But the pre-init white screen looked OK, so I was suspicious that it was functioning, but in a weird way. After some experimenting, I found that if I swapped the sync settings around and the horizontal/vertical addressing modes around it worked, but exactly backwards from what it should -- addressing was going the wrong way and scrolling was backwards, etc... It is usable, but only if I correct for their problem in software. I didn"t exchange either one of these because the cost and hassle of doing so wouldn"t have been worth it.I was also suspicious that the one screen that was behaving backwards simply had a different LCD driver chip. But, I read the Device ID out of all of them and they all reported 9325. So they should have all functioned the same. And, for what it"s worth, the LCD driver chip at least thinks it"s a 9325.As for software and support, I don"t understand the reviews that say there"s no software or support out there, as the item description posted on Amazon even has a link to a zip file from SainSmart with the CTE UTFT libraries already preconfigured for these screens (maybe those reviews were done before that was posted?). And in any case, this is a clone of the CTE (Cold Tears Electronics) boards and there"s plenty of documentation and software for it, including schematics and even board layouts, if you Google it.One reviewer mentioned it not being a true "CTE" board because no SPI Flash chip was installed. Well, even the original CTE boards don"t come with the flash chip by default -- that"s an optional add-on (as per their "official" website). This clone certainly has the pads, just get a chip and solder it on... Though you"ll probably still want to read the font data out and store it in memory, as the latency of reading it from flash every time text is rendered would serious slow down performance. So why not just put the font you want in the main flash of the micro? Though I guess you could use the chip to store anything you want and aren"t limited to just fonts.Another thing to look out for on the board is solder splash and cold solder joints, specifically on all of the through-hole parts. Two of my boards had a solder splash on the power input connector, shorting it out had I not seen and removed it. Various through-hole connectors were marginally soldered and needed some touch-up work. So expect to do some soldering right out of the gate. And be sure to look your board over thoroughly and fix these things before using it.The processor boards (apart from a couple of soldering issues) were fairly functional and I guess a decent value for the price. But, the Mega, for example, has a old bootloader version installed. One of the first things you"ll want to do is reflash it (via the ISP port) with the current stk500v2 bootloader. Also, it didn"t have the lock bits sets, meaning you could easily accidentally overwrite the bootloader during programming and end up with a brain-dead board until you reflashed the bootloader via the ISP port... So I suggest flashing the current bootloader and setting the lock fuses first thing.I"m suspicious, though, that the ATmega2560 processor is a counterfeit chip as the efuse bits don"t seem to want to stay set. You can program them, and they seem to program OK, even verify correctly, but later on will occasionally randomly read back as 0xFF. I have only seen that happen with the efuse bits, which is primarily just brownout voltage threshold setting, so it isn"t too critical (compared to the other fuse bits), but makes me wonder about the integrity of the processor as a whole and wonder if it"s possibly a "counterfeit chip".I haven"t done as much checking of bootloader code on the Due board, or its ARM micro. It came up and talked to the bossa loader without any issues, so I haven"t had a need to analyze it to the extent I have the Mega boards. Plus, being a newer Arduino board, it"s more likely to have a new bootloader and also the different nature of the programming process on the ARM of the Due isn"t as likely to have flash overwrite issues as the Mega does.The LCD screens themselves are decent, assuming yours isn"t cracked or wired backwards, but be aware that this 9325 chip, at least the way it"s configured on this LCD panel, does NOT support hardware scrolling in the vertical direction when in landscape mode. It does do hardware scrolling, but only vertical for portrait mode (or horizontal for landscape). If your project needs hardware scrolling in the vertical direction of landscape mode (as my project needs), this LCD screen won"t do it!The touchscreen, however, I found to work quite well -- but ONLY after you"ve calibrated it. It didn"t work at all until I did the calibration. Perhaps the reviewers saying they couldn"t get touchscreen to work didn"t calibrate it? You first need to get your LCD working with their demo. Then, load their UTouch calibration program and follow the prompts on the screen for creating the calibration parameters. Then plug those parameters into the UTouch source code, et voila. I was pleasantly surprised at how well the touchscreen seemed to function for the money -- it had good response, was accuracy and seemed repeatable, and didn"t require a lot of excess pressure, etc. From some of the other reviews I"ve seen on this screen, I wasn"t sure what to expect, but was pleasantly surprised to find the touchscreen performing well (at least on the screens I received -- maybe they too have quality control issues?).The UTFT code isn"t the best of code, but is functional and works well on both the Mega and Due. I did tweak it to work a little more efficiently and fix potential memory access faults, and to add hardware scrolling support (the library itself didn"t originally support hardware scrolling at all).A better software library to use with the screen is Andy Brown"s xmemtft, available on GitHub. To use it, you"ll have to use the Gpio16 include files for the ili9325 chip and properly set the port mapping for your processor. Speaking of port mapping, the correct settings on the UTFT library (that"s linked in the item description of these boards) for this 2.8" 320x240 TFT LCD in their example code is as follows:Mega:UTFT myGLCD(CTE28,38,39,40);UTouch myTouch(6,5,4,3,2);Due:UTFT myGLCD(CTE28,25,26,27,28);UTouch myTouch(6, 5, 32, 3, 2); (note: it will support "4" in place of the "32", but only if you add a jumper on the adapter shield)So all-in-all, it"s usable, but only if you do a little work on them, don"t get a bad LCD, and don"t need vertical scroll in landscape. It definitely isn"t a kit for a novice. Don"t expect to plug it together and start using it without doing some soldering and fixing things. And if you are new to programming, you may want to get some experience on a more ready-to-use package, like an Adafruit kit or something, first.But, if you don"t mind learning a little and working through the BS and you happen to get lucky and the one you receive isn"t defective, this is a decent deal for the money, as most vendors sell just the processor board for the cost of this entire kit.So, as a cheap, knock-off clone, it"s usable, but...
