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.
5) Insert the TF card into the Raspberry Pi, power on the Raspberry Pi, and wait for more than 10 seconds to display normally. But the touch is abnormal at that time, and the touch needs to be calibrated as the following steps.

Today, we are going to list down all of the best Raspberry Pi compatible LCD screens available online. These screens are ranked and rated based on the following factors.
Rule of thumb, larger the better. The best of the LCD screens for a Raspberry Pi we got here have a 1080P high resolution and is a full touch screen. There are higher variants available as well but we believe that this is a standard benchmark.
First on our list is an LCD touch screen straight from the official house of Raspberry Pi. It is a 7 inches large touch display that is specifically created for the Raspberry Pi board.
Next on our list is a screen by Kuman, one of the top manufacturer’s in the realm of hobby electronics. This one too is a 7 inches large TFT capacitative touch screen.
Yet another Kuman 7 inches HD Display Screen, this one is quite different from the previous Kuman display screen. That difference is not just in the screen resolution but in a wide range of other things as well.
In this entry, SunFounder comes with a 10.1 inches large HDMI supported IPS LCD display monitor. It has a high resolution of 1280 X 800 pixels and also comes with a camera holder stand.
Next on our list is another SunFounder Raspberry Pi Compatible screen. This one is a simple 7 inches large LCD Display screen with built-in speakers too.
Next product on our list is from a brand called ELECROW. Their LCD screen comes with 5-inches size display and high-resolution picture. It is a resistive touchscreen monitor and comes with a touch pen for easy use.
This LCD touch screen is from SunFounder which has similar dimensions and aesthetical aspect as the previous 10.1 inches Screen by SunFounder and are essentially the same. This is just an older model of the same product.
Display resolution or the modes is the number of distinct pixels in each dimension that can be displayed. It is controlled by many of the factors like CRT, flat-panel displays, and LCDs. If the resolution you opt is not compatible then the monitors will stretch and shrink to fit in the specified. It turns result in a great loss of the signal and quality.
A VGA is a 3-row connector that is provided on many of the display devices like computers, TVs, laptops, and projectors. It is a good quality cable that supports the signal within the bandwidth range of (2-MHz-500MHz).
Using the HDMI port to connect a Raspberry Pi to the LCD screen is one of the simplest and easiest ways to go. Here, all you need to do is to take an HDMI cable and plug it on both sides of the devices. One end goes into the HDMI port of the LCD screen and the other one will go right into the Raspberry Pi’s HDMI port. This set up does not require any special drivers software nor does it require any format of post plugin set up.
Raspberry Pi comes with a tiny 15 pin ribbon cable connector that can support a Display Serial Interface or a DSI standard. This enables fast communication between an LCD screen and the chip.
The Raspberry Pi 7″ Touch Screen Display from the house of Raspberry has a great colour output of 800 x 400 pixels and its capacitive touch is multi-fingered up to 10 fingers. That and the fact that it is specifically built for Raspberry pi Boards by the Raspberry company makes it the best Raspberry Pi LCD screen for your DIY Raspberry pi kit.
There are various smart shopping carts and baskets with the RFID, IoT, and embedded system. Nowadays, the effects of coronavirus disease (COVID-19) pandemic living for people around the world has made the changing lifestyle especially shopping at the convenience store and supermarket. In [5], the demonstration experiment of the RFID automatic checkout solution by Panasonic has been proposed. Customers can automatically checkout while walking through the checkout lane with the RFID on basket containing products. In [6], an application on a mobile application to search the shopping shelf in the supermarket has been presented to manage the shopping list.
For this research, we aim to minimize the production costs of a proposed basket by using the local products in Thailand. The contributions of this paper are summarized as follows: 1) to propose the design and implementation of the low-cost hanging basket based on the kansei engineering and 3F theory for the product design, and 2) to deploy a low-cost basket including with a Raspberry Pi 3 Model B+ SBC, a 1-dimension barcode reader, and a 7-inch TFT LCD display monitor touch screen connected inside the basket by using the online purchase application on the Raspbian operating system for payment.
The rest of this paper is organized as follows. Section 3 presents the proposed low-cost smart basket based on an ARM SoC architecture. Section 4 presents the smart basket algorithm. Section 5 presents the user interface. Section 6 details the experimental results and Section 7 concludes this research.
Low-cost smart basket part consists of the Raspberry Pi 3 Model B+ SBC with 1.4GHz ARMv8 SoC, 1GB DDR2 lowpower memory, a 64GB micro-SD storage, a full size of high definition multimedia interface (HDMI), and 2.4-5GHz IEEE802.11.b/g/n/ac wireless LAN. The DC power supply
10,000mAh 5V-2.5A, a 1-dimension barcode reads, and the 7-inch TFT LCD display monitor 800×480 of resolution with the capacitive touch screen control are installed. The Raspbian is used as the operating system. The component of Raspbian includes a Linux kernel 5.10.17 based on the Debian Linux, which is installed on a micro-SD storage in the Raspberry Pi.
The online banking block with the online purchase application for payment develops by the C/C++, XAMPP as a PHP development environment, HTML, and JavaScript are described in the Section 4. Figure 5 shows an ARM Cortex-A53 processor configuration with four cores and an AXI Coherency Extension (ACE) or the Coherent Hub Interface (CHI) Master Interface.
The 64-bit address version of ARM [14] is used. The CortexA53 processor is a mid-range and low-power processor installed the ARMv8 architecture. In this research, the 4-core Cortex-A53 processor is used with an L1 memory system and a single shared L2 cache [15]. There are several low-end IoT devices using ARM as a main processing unit [16] such as OpenMote, LSN50, Memsic Lotus, nRF51 DK, and Arduino MKR1000.
Kansei engineering (KE) has been used for the product design following the customer’s feeling and needs in the product function [17]. Following the KE concept, we set the adjectives of these influencing factors for evaluation as “weak to strong” on the 5-point scale. Following [18], the product design can be generally divided into three fundamental components as the appearance, functionality, and quality. The form follows function (3F) theory has been associated with the 20thcentury architecture, engineering, and industrial design related on the function or purpose.
Defining the pain points of consumers and solutions: In this step, researchers are looking for three different sizes and weights of a basket sold in the hardware stores. Type I, II and III are made from hard plastic material with 30×41×12cm/0.6kg, 17×27×21cm/0.2kg, and 44×33×25cm/0.7kg as shown in Figure 6(b).
The user interface for a smart basket design for Thai people customers composes of nine pages:1) a smart basket selection page is shown in Figure 9(a), 2) the product details page is shown in 9(b), 3) a new customer registration page is shown in Figure 10(a), 4) the customer login page is shown in Figure 10(b), 5) the products or stock management selection page ss shown in Figure 11(a), 6) the product management page is shown in Figure 11(b), 7) stock management page for tracking and monitoring stock ss shown in Figure 12(a), 8) the customer satisfaction questionnaires page is shown in Figure 12(b), and 9) the payment page is designed for customers to purchase items easily and securely in Figure 13.
Software test is repeated 100 times concerning with added/deleted products, registration/login and payment. Example of deteted product and online payment tests are demonstrated in Figure 15. The real usage of proposed basket is tested at the local supermarket shown in Figure 16.
