kuman 3.5 tft lcd shield datasheet in stock

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.

Note: There is a film on the LCD, if there is scratch on the film when you receive the item, pls try to remove the film with your finger nail from the corner of the LCD, thanks.

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.

Based on VE7JRO"s answer, I managed to map the connections by seeing where the connections would go if I just fit the connections shielding the Arduino UNO, the way VE7JRO suggested:

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.

This module is a 3.5-inch TFT LCD module with “320X480” resolution and 65K color display. It is suitable for Arduino Uno and Mega2560 development boards, and also supports SD card expansion function. It uses 8-bit parallel port communication, and the driver IC is ILI9486.

The 3.5-inch display is a ready-made shield for Arduino Uno, which can also be placed on the Arduino Mega. The pins of this shield are designed to be easily installed on the Arduino. The bad point about these modules is that they use all Arduino Uno pins.

Today, you will learn how you can create and use buttons in your Arduino TFT Touchscreen projects.I"m using Kuman"s 2.8" TFT Shield combined with Kuman"s Arduino UNO. Bonus: The TFT Shield from Kuman comes with a free Stylus which you can use for more precise presses!

Clip in the shield onto your Arduino board. Make sure it"s not in the wrong way!You can use the pictures above for reference. Plug in your Arduino board to your PC and hop into the Arduino Software.

I tried it with your sketch, but it did not work firstly. However I fixed some part of the sketch, it worked. "tft.begin(0x9325);" to " tft.begin(0x9341);"0

I have mirrored picture...i read datasheet of hx8347g...i found some register,but i dont know how set it to 6,7 bit to 0. Do you meet with this problem?
