ESP Easy is a free and open source MCU firmware for the Internet of things (IoT). [1] and originally developed by the LetsControlIt.com community (formerly known as ESP8266.nu community). It runs on ESP8266 [2] Wi-Fi based MCU (microcontroller unit) platforms for IoT from Espressif Systems. The name "ESP Easy," by default, refers to the ...
The ESP8266 is a low-cost Wi-Fi microcontroller, with built-in TCP/IP networking software, and microcontroller capability, produced by Espressif Systems [1] in Shanghai, China. The chip was popularized in the English-speaking maker community in August 2014 via the ESP-01 module, made by a third-party manufacturer Ai-Thinker.
On December 30, 2013, Espressif Systems [6] began production of the ESP8266. [12] NodeMCU started on 13 Oct 2014, when Hong committed the first file of nodemcu-firmware to GitHub. [13] Two months later, the project expanded to include an open-hardware platform when developer Huang R committed the gerber file of an ESP8266 board, named devkit v0 ...
Microsoft Fingerprint Reader was a device sold by Microsoft, primarily for homes and small businesses. The underlying software providing the biometrics was developed by Digital Persona. Fingerprint readers can be more secure, reliable and convenient than a traditional password, [ 1 ] although they have been subject to spoofing.
Common device driver compatibility issues include: a 32-bit device driver is required for a 32-bit Windows operating system, and a 64-bit device driver is required for a 64-bit Windows operating system. 64-bit device drivers must be signed by Microsoft, because they run in kernel mode and have unrestricted access to the computer hardware. For ...
ESP32 is a series of low-cost, low-power system-on-chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth.The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, an Xtensa LX7 dual-core microprocessor, or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise ...
It has 34 I/O pins; 64 KB RAM; 256 KB of flash; 2x16-bit ADC; 12-bit DAC; 3xUARTs, SPI, 2xI²C, I²S, CAN bus, Touch and other I/O capability. All digital pins are 5 volt tolerant. Teensy 3.2 adds a more powerful 3.3 volt regulator, with the ability to directly power ESP8266 Wi-Fi, WIZ820io Ethernet and other power-hungry 3.3 V add-on boards.
One reason for this is that an 8-bit gray fingerprint image is a fundamental base when converting the image to a 1-bit image with value 1 for ridges and value 0 for furrows. This process allows for enhanced edge detection so the fingerprint is revealed in high contrast, with the ridges highlighted in black and the furrows in white.
