kuman 3.5 inch tft lcd display driver price

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.

This Touch Screen Support for Raspbian/Ubuntu/Kali/RETROPIE systems, We provide drivers and image freely. (Please scan the QR code on the instruction to download it)

The Raspberry Pi screen can work with fbcp software driver, you can adjust the resolution by the software (The RPI screen original resolution is 320×480).

The Raspberry Pi Display support 125MHz SPI signal input, It can display stable without Flicker. When it work with Raspberry Pi, the refresh rate is about 50fps, it is enough to play the video and game.

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.

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.

Rotating the screen to the proper orientation proved challenging. The config.txt rotate commands don’t work with the raspberry pi4. I couldn’t get the xorg configuration to rotate the display. When I added kernel commandline parameters to rotate the display, that worked for the initial verbose boot screen… but once KlipperScreen loaded, it was the wrong orientation.

(3) Copy the local driver to the running Raspberry Pi system and execute the following command to extract it (can be copied by SD card or FileZilla software)

(1) After the LCD driver is installed, the system will automatically restart. After the startup is successful, the LCD can display and touch normally,

C. The retropie-rpi1_zero system cannot log in via SSH (no network port and wifi module). You need to copy the driver through the serial port. For details, see RaspberryPi Zero open serial instructions

After execution, the driver will be installed. The system will automatically restart, and the display screen will rotate 90 degrees to display and touch normally.

（" XXX-show " can be changed to the corresponding driver, and " 90 " can be changed to 0, 90, 180 and 270, respectively representing rotation angles of 0 degrees, 90 degrees, 180 degrees, 270 degrees）

Looking at the Xorg.0.log file seems to indicate that the Display can no longer be found. I have double checked that all configuration settings made to enable to display are still there. Even tried to re-run the installation scripts, however this does not solve the issue.

After some further Googling I stumbled upon the Kuman website with the Display in question (hxxp://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). They seem to have a support section for the display with a link to the "latest" drivers. IT is a link to a mega.nz file share, https://mega.nz/#F!HUFQFDwL!fhM7RPrhbMJLsZ7ISLEr0A!2JNQAaII. These drivers however also do not fix the issue.

I contacted their support to see if they could either supply the drivers for the new kernels or give some indication on how to get them to work. their response consisted of a single line: "Sorry, we do not have that.". I am therefore unsure if any additional help to solve this issue can be expected from their side.
