kuman 3.5 inch tft lcd display setup factory

I have a perfectly running Raspberry Pi 3 Model B, with a Raspbian Distribution on a 16 GB SD-Card. I connected a Screen with a HDMI-to-DVI Connector to it, a Mouse and Keyboard and I also have SSH access. Further I got a Kuman 3.5 Inch Touch-Display, which I want to use on it. I read myself through the Internet enough that I know I can"t use the Screen and the HDMI-Screen simultaneously. So I connected the Screen to the right Pins, the Backlight already works. So I take the Drivers that are sent with it. Searched the one for my Distribution, extracted the Script onto my Raspberry Pi and launched it through./LCD-35 in the terminal. After a few seconds it Reboots and the Color-Test appears. The Screen for the NOOBS-Recovery-Mode appears, which I can still use, then a few seconds later:

UPDATE: I installed a IMG of Raspbian sent with the Display, which worked, let"s say 50 %. It worked as a mini-screen, but not more. The touch wouldn"t work. I tried to calibrate it, read and did the instructions for my screen, but nothing helped. It"s not the original problem but I"d still rather install it on a working system without the special Raspbian.

Understanding that many people have problems configuring their Kuman TFT display on the Raspberry Pi together with RetroPie, I have decided to make this step-by-step of how to install the Kuman TFT 3.5" display which you can connect directly to the GPIO ports of the Raspberry Pi and run your applications. A lot of people have been buying this Kuman display from Amazon and other online markets for its economical price but it is not an easy display to install for certain applications, compared to other displays that come with integrated HDMI ports that will surely be a lot easier to manipulate and start working.

I advise you to buy a GPIO cable or a ribbon cable to connect the display to the Raspberry Pi, because sometimes (and it happened to me) at the time of manipulating the display and fitting it on the pins of the Raspberry, the screen being so the thin can be broken easily.

Next, copy the following code to download the best driver from Github:git clone https://github.com/goodtft/LCD-show.gitchmod -R 755 LCD-showcd LCD-show/chmod +x LCD35­-show./LCD35­-show

If, after installing, the screen is a mess together with the TV missing icons or words, please connect via SSH to your Raspberry Pi and run this command:cd RetroPie­-Setup/sudo ./retropie­-setup.sh

The previous command will open the Retropie configuration file where in the end you have to look for something like SPEED and FPS and change the values to something like:dtparam=audio=ondtoverlay=tft35a,speed=62000000,fps=40,rotate=90#dtoverlay=ads7846,cs=1,penirq=17,penirq_pull=2,speed=25000000,fps=20,keep_vref$gpu_mem_256=128gpu_mem_512=256gpu_mem_1024=256overscan_scale=1

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.

Display brilliant colors on the Displaytech 3.5 inch TFT LCD module! This LCD display has 320 x 240 RGB resolution and uses the NewVision NV3035C single chip digital driver. The TFT driver IC supports 16M colors allowing for a range of hues to be displayed and can also support up to 22 different types of input video formats within RGB, CCIR656, and CCIR601 video formats. The 3.5” TFT is available with a touch screen panel in either resistive (single-finger or stylus pressure) or capacitive (five-finger, multi-gesture) touchscreen technology.
