kuman 3.5 inch tft lcd display 480x320 made in china

The RPi LCD can be driven in two ways: Method 1. install driver to your Raspbian OS. Method 2. use the Ready-to-use image file of which LCD driver was pre-installed.

3) Connect the TF card to the Raspberry Pi, start the Raspberry Pi. The LCD will display after booting up, and then log in to the Raspberry Pi terminal,(You may need to connect a keyboard and HDMI LCD to Pi for driver installing, or log in remotely with SSH)

1. Executing apt-get upgrade will cause the LCD to fail to work properly. In this case, you need to edit the config.txt file in the SD card and delete this sentence: dtoverlay=ads7846.

This LCD can be calibrated through the xinput-calibrator program. Note: The Raspberry Pi must be connected to the network, or else the program won"t be successfully installed.

3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.

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.

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.

So going to suggest that is a place to start, do double check all the pins since while the controller is the same whoever built the display may have swaped physical positions around, and it"s also not impossible for there to be different resolutions etc you need to tweak if the chip is using different physical displays but in this case suspect you are good to go.

@ bossredman- The XPT2046 is actually the touchscreen controller, not the TFT display controller. You say you don"t care about touch. The existing Teensy/Adafruit TFT display library is written for the ILI9341 TFT controller. This controller is capable of 320 X 240 max resolution. Your display is twice this. I strongly suspect it uses a different controller, so the existing library won"t work. That said, there is no reason the Teensy couldn"t drive your display if you can find a suitable driver. I have not personally seen other, higher resolution driver libraries mentioned in this forum, but others may have info that might help in this respect.

There are RA8875 based 5" and 7" TFT displays, and sumotoy has written a library for those. I"ve also used one and wrote my own driver (for ugfx) so that display family might be an option.

@bossredman: Since you are in the UK, you should take a look at the FT800 controller-based displays from FTDI, the UK firm that makes them. They have a very high performance TFT driver/graphics engine and you can get 3.5- 5" displays for less than the combo you listed above. FTDI supplies Arduino drivers for these displays- which I have used with the AVR chips found on Arduino boards in the past.

I took one of my spare FT800 4.3" TFT modules and wired it up to a spare Teensy LC I had on hand. The FTDI demo programs worked fine when compiled for Teensy LC- no changes needed. Should work OK on T3.6 as well. When I get a chance I"ll try it on my Kickstarter T3.5 module- I don"t have the T3.6 though.

I wrote several magazine articles centred around these FTDI FT800 displays a few years back, and I was impressed with them. The library routines are a bit harder to understand than the Teensy ILI9341 library, but this controller is MUCH more powerful.

Actually, I was looking for the wiring for a Teensy 3.2, not an STM. I saw your #defines in the code, they didn"t relate to the Teensy and my display which has different pin descriptions

MISO, MOSI and SCLK are necessary for the TFT to work. They are not exclusive of the SD card. The SPI interface is a bus: you connect the same SCK, MISO and MOSI to all the pertinent devices, then each device has its own CS=chip select.

I would like to use a ILI9486 TFT and TP with it. They both work fine with a Mega2560 and when I wire it up as per the declarations in https://github.com/palmerr23/ILI9486_Teensy_Library .h file and run the graphictest program in the examples folder, the screen lights up, but doesn"t reset or show any data. I"m wiring as follows;

As Kurt says, it"s important to know exactly what TFT hardware you have, and particularly if you have any other hardware or (particularly) SPI-related libraries used. Uninitialised SPI hardware can sometimes transmit on the bus, if the CS pin hasn"t been intentionally driven HIGH.

Turns out the board is SPIO for touchscreen and parallel for LCD. My mistake. I bought it on the basis it was SPIO for both. As a shield, it just plugs into a UNO/Mega. It"s only by going via a breakout board and wiring every pin and seeing when it breaks, I was able to confirm that the LCD is using the parallel interface.

Might try using the breakout board to wire the parallel interface to Teensy and test that or more likely, I"ll use this as an excuse to buy a larger (7") TFT which is definitely SPIO :-)

Is it this one: http://www.kumantech.com/kuman-35-inch-tft-lcd-display-480x320-rgb-pixels-touch-screen-monitor-for-raspberry-pi-3-2-model-b-b-a-a-module-spi-interface-with-touch-pen-sc06_p0014.html

Nto sure if RS is DC or not.. Maybe, but maybe not... Some like the KeDei display for RPI have a real screwy interface, using shift registers, and this may be similar...

Beware though. I"m not out to bash BuyDisplay, I"ve used many of their displays in my projects. Mostly the 3-inch ILI9341 display with xpt-2046 resistive touch and the 4.3-inch display with capacitive touch and the 5206 (?) touch controler which both worked very well. They also have other touch controllers such as the GSL1680 on their 5-inch RA8875 display. The display is super nice and the display drivers work well with it. It"s the dang GSL1680 touch controller that has been a bear to get working, YES, I"m still trying. Some folks posted here that they got it working but I have had no such luck. So when you buy at BuyDisplay be sure to verify the touch chip you are getting. Besides that I do feel BuyDisplay is a good place to purchase displays. No bad feeling intended to other display vendors.

Yesterday, I wired the waveshare 4inch tft touch screen to teensy 4.1. One thing I had to change was the spi config on the display board. There are three switches to select the six pin spi connector or the outboard pins for spi.

In cases like this it really helps others to help you, when we have additional information. Things like what display is this. I suppose we could do a search to see what boards waveshare produces that happens to be 4". What library are you using?

I don"t remember if this one in SPI mode uses 18 bit colors 666 (24 bits to SPI) per pixel or if it can use the 565 16 bit color like many of our displays do. The 88 can only do this in parallel mode.

The touch screen LCD is ready with 320×480 resolution, 50 FPS (Frame per second). Resistive touch control is being supported by the Raspberry Pi OS or Raspbian (directly-pluggable). However, we will still need to install the driver for graphic display :)

However, there is a dedicated case/enclosure and a low-profile heatsink with a fan for this LCD to fit perfectly on the Raspberry Pi 4 Model B. The case has an opening for the LCD, and the low-profile heatsink with a fan keeps the Raspberry Pi 4 Model B protected and cool! You get a perfect console :) Don"t forget to remove the top lid/cover of the enclosure for the 3.5-inch LCD.

Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.

As we understand, Raspberry Pi 4 Model B delivers great performance and of course, more power will generate more heat as of all CPU :) So we need a way to install an additional heatsink to dissipate the extra heat. It will be better if we can have the option to add a cooling fan for active cooling. Well, this 3.5-inch touch screen LCD comes ready with the heatsink and cooling fan for you to use with the Raspberry Pi 4 Model B. it solves all the concerns.

The 3.5-inch touch screen uses the GPIO on the Raspberry Pi board, so it stretches out 2 pins as the power to supply the cooling fan on the low profile heatsink, and keep the Raspberry Pi board cool!

Note: The Raspberry Pi 4 Model B, 3.5-inch Enclosure, and the Low-Profile Heatsink with a fan are NOT INCLUDED in this product, please get them separately.

The Graphic driver is provided and can be downloaded for Raspberry Pi OS/Raspbian. It also supports Ubuntu and Kali Linux. Do follow the steps here: http://www.lcdwiki.com/MHS-3.5inch_RPi_Display

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.
