kuman tft lcd 3.5 supplier

The 3.5 in Touch Screen can support two screens simultaneous display(the Raspberry Pi can be connected to this screen and another HDMI screen at the same time).

This 3.5 inch resistive Touch Screen can be directly inserted into any version of the Raspberry Pi (Raspberry Pi zero, zero w, a, A+, b, B+, 2B, 3B, 3B+).Raspberry Pi is not included.

A beautiful 3.5” touchscreen display, based on ESP32-WROVER, with a built-in 2M pixel OV2640 camera, makes it an ever perfect platform for your ESP32 projects.

Makerfabs ESP32 3.5” Touch with camera is absolutely open for makers, and besides, Makerfabs provide plenty of Demos to help the users on the usage. Have a try at this fantastic display in your next ESP32 project!~

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.

I bought online this LCD Touchscreen Kuman SC3A-NEW-UK. It uses ILI9486 drivers, but it didn"t include any instructions manual, and kumantech.com seems to be devoid of complete technical documentation about SC3A-NEW-UK model.

Just in case it wasn"t noticable: I am trying to make a "Hello World" for my SC3A-NEW-UK"s LCD Touchscreen from an Arduino UNO board. In other words: just print "Hello World" to see if it works.

This compiled in Arduino IDE, no problem, but I still don"t know if it will work well with my screen. I am also confused about initialization of the TFT object and how would I have to wire the LCD screen to the Arduino depending on this initialization:

...i mean, my LCD screen has CS and RESET pins, but what is DC supposed to be here? (in this context, I don"t think it stands for "Direct Current"... but there"s no DC pin reference in my LCD screen written "AS IS"... ?? This brings me more confusion...

...specially having in mind that I don"t know how am I supposed to wire the LCD screen to the Arduino yet. It seems the LCD pins have been designed to fit in directly to the Arduino board without thinking too much about it (like the shape is the same), but that would make the screen getting all the Arduino UNO"s pins for itself, so I don"t think so...

...so, powering the screen shouldn"t be a big deal, but, how am I supposed to connect everything else? I am completely misguided about how am I supposed to interact with the screen from Arduino code... what is RS pin for? Should I use 4-bit or 8-bit mode? (I think 4-bit would imply connecting 4 digital pins for the screen, and 8-bit the whole 8 pins from screen to the Arduino UNO board)? Should I use LCD_RD and LCD_WR? Well you have a picture of my confusion.

Even though I know how to control Input/Output in Arduino code to interact with analog/digital input and output pins at will with C++ in Arduino code (but even so, I think I"m still an Arduino n00b), this LCD screen"s physical interface is very confusing to me...

PD: I have read somewhere that this SC3A-NEW-UK Touchscreen is made to shield Arduino MEGA boards (by fitting the PINs directly into it), but mine is an Arduino UNO Board! (perhaps I shouldn"t have bought This LCD model, then?)... but I have sets of wires, pinboards and stuff... I don"t want to give up the idea of harnessing this LCD screen using an Arduino UNO. I don"t care about shielding feature, I just want to wire it and make it work. I will figure out how to shield electronics later on.

I put NONE for A5 input, because that pin of LCD screen doesn"t have any name on it. There are another ones without name as well, that I didn"t include in this table. I believe (perhaps I"m wrong believing it, I don"t know) that those pins without name have no use.

I still don"t know much of the details about what pins do what for the screen, but I have read somewhere that LCD_D0 to LCD_D7 are meant to receive digital data in some kind of 8-bit parallel mode. But I also heard that there is a 4-bit mode. If I could use that mode with this screen, I would be able to have 4 free digital pins for anything else...

I tested VE7JRO"s code. LCD Screen did draw the interface as expected. But buttons didn"t respond. I found out the code sample needs further calibration.

The fifth parameter is supposed to be the resistance measured between LCD_D6 and LCD_RS with the screen unplugged. Unfortunately, my multimeter can"t measure it for some reason (I put it in 2000 Ohms mode for reading resistance: I always get "1", the same than when I don"t connect anything... like if multimeter"s contacts aren"t working well, I don"t know)... so I left the default 300 value.

i had the same issues with this 3,5" TFT LCD and wiring it to an ESP32 and making the TouchScreen work. However i managed to find a solution to the problem. Lets start with the wiring:

Tips for driver: After install the driver that could get the touch function work. 1.)Step1, Install Raspbian official mirror a)Download Raspbian official mirrorï¼^latest versionï¼?: https://raspberrypi.org/downloads/ b)Use"SDFormatter.exe"to Format your TF Card c)Use"Win32DiskImager.exe" Burning mirror to TF Card 2.) Step2, Clone my repo onto your pi sudo rm -rf LCD-show git clone https://github/goodtft/LCD-show.git chmod -R 755 LCD-show cd LCD-show/ 3.)Step3, According to your LCD"s type, excute: In case of 3.5" LCD sudo ./LCD35-show If you need to switch back to the traditional HDMI display sudo ./LCD-hdmi Wait a few minutes,the system will restart automaticall , enjoy with your LCDKey Parameters LCD Interface: SPI LCD Type: TFT Backlight: LED Colors: 65536 Aspect Ratio : 8:5 Resolution: 320*480 DOTS Power Consumption: TBD Backlight Current: TBD Package Contains 1x 3.5inch LCD for Raspberry Pi 1x CD instruction Note:Installing on existing systems is not supported. Please backup your system before attempting this If you want to use the 3.5inch at your current system, you should add the Driver debugging system by yourself (need more time to do that ). So we suggest that you use our Driver debugging system and then the 3.5 inch lcd panel can be working well. regarding Our debugging system, Write the System Image(Raspbian) to the SD card in Windows,Mac OS X or Linux.We have tutorials and software for you to download, please contact us to get all information. 3.5inch Raspbian image software: PI 3-LCD35-2016-03-18-raspbian-jessie PI 2-LCD35-2015-03-03-raspbian-jessie

4) Please note that you need to install our jessie OS with the pre-installed drives on a new or format SD card, if you dont install our jessic OS with the pre-installed drives, you will be starting at a white LCD panel.We have do test on OS, if you want to use other system, maybe you need to add drivers by yourself.
