For this project I used a 2. The first phase of the is project is to try out the colour display. I used a 3. I chose this board because, although the seller of this display claims that it will work at both 5v and 3. So, rather than have to use level shifters of resistor dividers, I made the whole project run at 3. Pins 1 - 5 are for the touch screen and I will add these connections to this page once I have tried it out. The code says that the reset is optional, but, as before, I had to enable it to get my display to work.

You must complete the first section so you will have downloaded and installed these two libraries from ADAFruit:. The code says that the reset is optional, but, as above, I had to enable it to get my display to work. Then change line 46 to match the name of your bitmap file. Jump to: navigationsearch.

CS chip select to A3. ILI is integrated inside the display. It drives the display and has nothing to do with touchscreen Although the shield connects some pins of ILI together with pins of the touchscreen. To read a byte from ILI after sending a read command e. Then command 0x2Ch.

Then send in sequence for every single pixel in the area a value of the color to display. The color has 2 byte format. The touch screen is attached on the surface of the display.

So you can't write to LCD display and read the touch screen in the same time. Wikipedia: Touch-screen devices using resistive technology, a two-dimensional membrane potentiometer provides x and y coordinates.

The top layer is thin glass spaced close to a neighboring inner layer. The underside of the top layer has a transparent conductive coating; the surface of the layer beneath it has a transparent resistive coating. A finger or stylus deforms the glass to contact the underlying layer. Edges of the resistive layer have conductive contacts. Locating the contact point is done by applying a voltage to opposite edges, leaving the other two edges temporarily unconnected.

The voltage of the top layer provides one coordinate. Disconnecting those two edges, and applying voltage to the other two, formerly unconnected, provides the other coordinate. Alternating rapidly between pairs of edges provides frequent position updates. An analog-to digital converter provides output data.

First we need to detect if there is a touch. Then we need to read a position of a touch. Touchscreen I tested sometimes wrongly detects a touch, outside of the touched point.

To prevent this I added some delays and the X and Y analog value is read repeatedly and touch is approved only if values do not differ a lot. Please log in or sign up to comment.

Raspberry Pi Stack Exchange is a question and answer site for users and developers of hardware and software for Raspberry Pi. It only takes a minute to sign up. Here is the link to the producer's page.

It has an ILI chipset, according to the producer. I searched around the web about how to wire it up and make it run on Raspberry pi.

The little screen accepts 5 interface modes: bit, 8-bit, bit, 9-bit and SPI. I found this site where a guy hook the same type of screen on a Rpi. The thing is, his pins are different from mine! I don't have those pins on my LCD board. In fact, the screen is driven with 3. The following are my pins:.

And his driver will work for me without frying my Rpi, that is? And what about the touch feature? How do I hook-up it? How can I find a driver for it? Any help is fine!

Asked 5 years, 10 months ago.The resolution of this TFT display is x which means it has pixels. This module works with 3. The ILI TFT display board which is shown in the circuit diagram above has 14 pins, the first 9 pins are for the display and the other 5 pins are for the touch module.

MOSI: master-out slave-in. SDI: serial data in. MISO: master-in slave-out. SDO: serial data out. The display module is supplied with 5V that comes from the Arduino board. This module has a built-in 3. To connect the Arduino to the display module, I used voltage divider for each line which means there are 5 voltage dividers. Each voltage divider consists of 2. The second library is Adafruit graphics library which can be installed also from Arduino IDE library manager.

ZIP Library … and browse for the. The same thing for the second file. The previous 2 libraries are included in the main code as shown below :. And this one shows Proteus simulation not perfect result! Proteus simulation file download link is below, use version 8. I am trying to confirm that but wonder is you know the answer to this. The shield version works fine and must have logic level converters built in. Thanks, Jack. Here is the backside of my ILII ordered a x pixel 2.

The only problem was that there wasn't a guide to how to get it working! When I figured it out I thought I'd make an Instructable for anyone with the same issues. It actually turned out to be quite simple. This tutorial doesn't show you how to use the SD card functionality.

The Ethics: A couple of users have complained that I am using adafruit libraries and I am not supporting adafruit. I'd like to point out that adafruit provide their libraries under The MIT License, which amoungst other things says:.

If you have an issue with the ethics, I'd like to point out that my behavior is perfectly legal so please keep your rant elsewhere.

Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. My setup is a little like this although I ordered my components separately. Luckily for us, Adafruit have a very similar display that they have written libraries for. I have the display which is powered by the ILI driver so I installed that library so I assume if you have a display with the ILI driver it works exactly the same with the other library that I linked.

I haven't seen any other drivers used but if you do, I recommend searching the Adafruit libraries on github. You also need to install the Adafruit GFX library regardless of what driver the display uses. Instructions on how you do this are on the github pages linked. If you are getting an error message complaining about these characters try removing them from the folder names but not the names of the. You have to wire the display up in accordance to the pin definitions there.

I'd like to emphasize that this display uses 3. This is information that I found on some forum somewhere and using it I got my display to work. However: I now have multiple of these displays from different sellers and perhaps different factories. I have noticed that some of them also behave using 5V logic. Upload the example sketch and give it a go, the sketch shows you well how to control the display. You may have to fiddle with the voltages for your particular model.

There are various options you have here -potential dividers on each pin, level shifters, or simply powering your arduino with a 3.The answer of course depends on the exact model of the TFT that we have on hand. The below instructions apply to a generic 3. This is nice, but I want to use a standard pin ribbon cable which I have left over from an old computer, and its conductor numbering is a little different.

So I came up with what you see here:. What we have here is the actual conductor number in the grey background counting the conductors in the ribbon cable from left to right and then above and below them the corresponding signal lines according to the above pinout.

Above and below the signal lines I have noted the actual Arduino pins that correspond to the signals. For example, pin 2 the second pin on the flex cable looking at it from the left corresponds to the DB0 signal which should be connected to the D37 pin on the Arduino MEGA or Due.

So we have to connect signals D0 through to D15 to the necessary digital pins. This leaves pin 1 which must be connected to ground and pin 3 which must be connected to Vcc which in our case is 5V. Note that I have not really gotten around to using the touchscreen capabilities or the SD reader, so I have not connected them to my Arduinos. Now, there is one more thing that I should point out and it is very important.

You need to connect a 10K resistor in series with each and every one of the lines. Do not forget to do this! In case of the Due the resistors are not necessary since it uses 3. I have the latest version 1. Arduino: 1. Would you mind showing your pin interface? I think buying the shield is pointless because i have more going on with my arduino than just a TFT, I would appreciate any help you could give!

Just a catch — as every pair of two pins are alternated — which means you must be careful at the Arduino end of the cable!! It is definitely not the best way of doing things but it limits the current just enough so that it does not cause damage.

A more proper solution would be a voltage divider built with 2 resistors, but that would not be easy to do without a PCB. Also practically same price with the MEGAs.

Following your good explanation I cabled my 3. Any suggest? I understand. But in your opinion the five pins that drive the touch should be connected to 3. I have this doubt. Otherwise you would be looking for trouble. Great post! Followed your directions including putting a 10K resistor in series with each line and it worked perfectly the first time after wiring it up to my Mega Thanks, you made it easy!

Good night, you could provide the schematic? I am following the tutorial, but I am finding it difficultand the code also to be able to have a refrenceI thank you. Hi there! Which schematic and code are you referring to?Pages: [1] 2. I did so with my Uno turning the LCD into a live speedometer with history for another Arduino robot running in my motor test station. The only drawback is that switching cables is needed when going from programming to running and back in order to avoid 5V damage on ILI LCD display.

Absolute maximum rating for VCC is 4. You can run your module with 1k0 series resistors to the 5V Arduino. Much simpler than level shifters.

But the easiest of all is to run at 3. Use the 5V output to supply the backlight through a small resistor.

You can always hand-wire some protoboard to accept your cheap 3. Hand wiring an "Adapter" is quite hard work. Especially when you can buy a ready made UNO shield that has all the correct electronics. I have done both methods. That way the Nano as my 3. A colleague told me to use a silicon diode to subtract 0.

With a second unmodified cable I did read 4. Just for completeness, I tested flashing programs as well as doing output to Serial console, no problems. You are obviously obssessed with disobeying data sheets. You can either use level shifters or series resistors.

Just run it at 3. But since my last ProMini died two weeks ago, new 1. So what can happen? Currently everything runs fine and nothing needs to be changed. Just in case the Nano will suffer from run at 3. If I am correct the laptop USB port cannot suffer from reduced 3. And since display gets the 3. The USB will be fine with 3. These are the absolute limits. The TFT will be fine at 3. You implied that you did not want to use either method. Which means that you just have to wait for your 3.

Just learned again that TFT display does not work with too much voltage. I had to discharge the LiPo battery to 3. Why do you want to risk damaging your TFT?

Then power your Pro Mini from the 3. Supply the backlight directly from the LiPo via a small resistor. This will give you 3. Your Pro Mini will work fine at 16Mhz and 3. Disconnect your display when uploading a new sketch.
