sainsmart 3.5 tft lcd raspberry pi quotation

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.

SainSmart 3.5 inch TFT LCD module is a special design for Raspberry Pi for portable application. It features a 3.5 "display with 320x480 16bit color pixels and resistive touch screen. The LCD is well mated with Pi board and interface with Pi via the high speed SPI port, and support console, X windows, displaying images or video etc. It therefore Provides 4 press buttons for user defined functions.

RPi LCD needs to use a SPI interface, but in the original image file of Raspberry Pi, the displayer is driven via a HDMI port. So the original image is not applicable for RPi LCD, and you should install the LCD driver to your Pi or use the Ready-to-use image file provided by Sainsmart,click here.

Download the LCD driver and extract it to your Raspbian OS (e.g. copy the driver to your Pi by sftpor using U disk). Then run the following command via putty:

This LCD can be calibrated using a program called xinput_calibrator which is pre-installed on the offer image. However, it was not pre-installed on original Raspbian OS. So in this case, you should get and install the program manually with

After running these commands, there will be a prompt for four-point calibration shown in the LCD screen. Click the points one by one to finish the touch calibration. Then, the new calibration data will be displayed in the terminal, as shows below. Please get these data for future use.

3.5 inch RPi LCD V3.0 HVGA 480X320. There is a XPT2046, 74HC04D, 74HC4040D, and 2 74HC4094D chips on the back. Is there a way to determine which driver I need to use in software?

I am not 100% convinced that the distribution given works with the LCD (the item I bought is dis-continued but the seller provided another item that has identical specifications - 3.5" IPS 15fps 480x320 resolution - but I suspect it has a slightly, or altogether different, controller.

[*]Is there any way I can extract some information of what driver has been used, or tried to use, for the TFT via that half working distribution? As far as I know, a GPIO/ SPI connection will not gather connected hardware information...

I bought a display off Amazon described as [ SainSmart 3.5" inch TFT LCD 240x320 RGB Pixels Touch Screen Display Monitor For Raspberry Pi for Model B & B+] and sold by: Sain Store. What I received is the 320x480 display you described. I am also trying to verify the model before I try to set it up.

The TFT isn’t ‘plug & play’ with the Raspberry, a patch has to be applied to the kernel to be able to interface via SPI with the ST7735R controller chip on the TFT. Once working, the display will act as a framebuffer device.

As it takes over three hours to compile the kernel on the PI, I will show how to cross compile from another Linux PC. In my case, it is Ubuntu 12.10 running within VMWare on a Windows 7 Quad core PC. Kernel compile time is 15 mins.

-Copy config from the Raspberry Pi to the Ubuntu box using SCP. Replace ‘raspberrypi’ below with the IP address of your Raspberry Pi if hostname lookup fails.

If you are planning on displaying the console on the TFT, then enabling these options in .config will allow you to change the font size and rotate the display later on.

To enable parallel processing for a faster compile. If you have a dual core processor add -j 3 to the end of the command below. If you have quad core, add -j 6

The last step below is to SCP the files from from Ubuntu to the Raspberry Pi. If you have trouble SCPing into your Ubuntu box you may need to install open SSH on Ubuntu with sudo apt-get install openssh-server. This step also copies the files from my home folder ‘mark’… yours would be different.

If you build the st7735 driver pair as built-in, add these options to the end of the line in /boot/cmdline.txt. This will display the console on the TFT.

Powerful High Resolution Laser: The beamo ultra thin laser engraves at an exceptional depth down to 0.05 mm layer with a clear resolution of 1,000 DPI fitting for any craft or small business project.

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

Note: Please use the recommended system for the touch screen. If another system is used, it may not have the touch function or may not work. You need to configure it yourself. Because there are many systems that the Raspberry Pi can use, we can’t make every system compatible with the touch screen.

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.

It is recommended to use a 5V/2A power adapter for the Raspberry Pi other than USB connection, otherwise, the Pi may fail to start up because the PC"s USB port might have not enough power.

I"ve been using the Sainsmart 3.2" and 3.5" TFT LCD (http://www.sainsmart.com/sainsmart-3-5-inch-tft-lcd-320-480-touch-screen-display-for-raspberry-pi-2-b-b.html) with my Raspberry Pi 2"s. I recently bought the Pi 3 and can"t seem to get the screen working.

It seems to fail at the point I download notro"s drivers from github (they download successfully, but on reboot, all I see on the hdmi display is the colored test square, and the SPI display is still backlight white with no image). It fails on this step even if I mix up the order.
