Fingerprint Identification with STM32 MCU and Serial TFT LCD Module

CNXSoft: This is a guest post by Amy working for STONE Technology, a company specializing in industrial liquid crystal display modules This month, I planned to develop a fingerprint door lock project. When I selected the fingerprint identification module, the project was suspended. However, I thought that since the fingerprint identification module had been purchased, I would simply test it. This fingerprint module can be easily purchased online, connected over UART to an MCU board. It supports fingerprint scanning, fingerprint entry, fingerprint comparison, and fingerprint deletion. Since the fingerprint module manufacturer provides a demo program for STM32F103 series microcontrollers, I bought a small development board based on STM32F103C8T6. The demo program of the fingerprint module uses LED lights to prompt the user to enter the fingerprint and compare the status (success or failure). But I want to use an LCD display, so I chose a 480×272 resolution serial LCD display. […]

BOE Showcases Rollable Displays for Smartphones (Video)

Companies have already announced foldable smartphones, but another type of smartphone may soon come to retail shelves as BOE showcased rollable displays for next generation smartphones at SID Display Week 2019. BOE, a China-based tech company, is a global leader in the semiconductor display industry. In addition they are an IoT company providing intelligent interface products. Also, they produce Interface Devices, Smart IoT Systems and Smart Medicine & Engineering Integration. In the video, you can see two different foldable phones, one which is about 7.7 inches display but, can be folded into a 6 inches display. And another rollable smartphone, which is up to 12.9 inches, the main attraction of the day. The 12.9 rollable smartphone, although still a prototype and not ready for the market, showed a lot of potential. With the plan to add more features to future versions, this smartphone, BOE is really heating things up. Additionally, it […]

Maixduino SBC Combines RISC-V AI, Arduino Form Factor, and ESP32 Wireless Module

Last year RISC-V cores made it into low-cost hardware with neural network and audio accelerator to speed up artificial intelligence workloads at the edge such as object recognition, and speech processing. More precisely, Kendryte K210 dual-core RISC-V processor was found in Sipeed MAIX modules and boards going for $5 and up. Since then a few other variants and kits have been made available including Seeed Studio Grove AI HAT that works connected to a Raspberry Pi or in standalone mode. Seeed Studio has now released another board with Kendryte K210 RISC-V AI processor, but based on Arduino UNO form factor and equipped with an ESP32 module for WiFi and Bluetooth connectivity. Meet Sipeed Maixduino SBC. Sipeed Maixduino specifications: AI Module – Sipeed M1 with Kendryte K210 dual-core RISC-V processor @ 600 MHz, KPU Convolutional Neural Network (CNN) hardware accelerator, APU audio hardware accelerator, 8 MB general purpose SRAM including 5.9MB […]

$40 Elecrow 5″ HDMI Raspberry Pi Display Features Backlight Control, a Resistive Touch Panel

There are plenty of small touch screen displays for Raspberry Pi board, including the official 7″ display that connects to the board’s MIPI DSI connector. Some people may prefer getting a small HDMI display however, as it can be used with most devices with an HDMI input port, and the touch screen function may be achieved over USB, I2C or SPI depending on the design. Elecrow has just launched a new 5″ HDMI display with resistive touch screen designed for the Raspberry Pi boards, and whose main feature is to support backlight control over GPIO 11 in order to lower power consumption according to the announcement tweet from the company. Specifications for RPD19048A display: Screen – 5″ TFT resistive touch screen display with 800×480 resolution @ 60 Hz; LCD Driver IC – Display Future ILI9486L (Likely wrong as this only supports 480×320 resolution) Touch controller – XPT2046 4-wire resistive […]

TAIHE Gemini is a 15.6″ Full HD or 4K Portable Display (Crowdfunding)

TAIHE Gemini 4K Portable Touchscreen Display

Portable displays have been available for a while, but they used to be fairly heavy, as for example, Gechic On-Lap Monitor 2501M 15.6″ portable monitor weighted 1.3 kg with cover. However in recent times, we’ve seen several such products – LAPSCREEN and DUO Add-on Display – launched with lighter designs, and the advance as USB type-C and power delivery make those even more attractive since a single cable can be used to transfer video, and power both the display and the host device. TAIHE Gemini is yet another option, but at 15.6″ is larger than the two aforementioned products, it is equipped with its own battery and kickstand, and comes in two variants with either 1920×1080 Full HD or 3840×2160 (4K UHD) resolution. TAIHE Gemini FHD & UHD portable displays specifications: Display Gemini FHD – 15.6″ 10-point touchscreen IPS display with 1920×1080 resolution, 15ms response time, 180° kickstand Gemini UHD […]
