Arduino library for the I2C LCD display, typical 20x4 characters. The library is inspired by the excellent New-LiquidCrystal library by F. Malpartida. Therefore the interface is kept quite identical, ...

LiquidCrystal Arduino library for I2C LCD displays used for STEM schools. Tested on HD44780 LCD connected to PCF8574 I2C.

Strictly speaking, a Theremin uses a pair of antennae that act as capacitors in a specific R/C circuit. Looking at [aritrakdebnath2003]’s MIDI THEREMIN, we see it works differently, but it does play ...

UART、I2C、SPI都是常见的低速板级通信协议，目前主流的SoC都内置了这些通讯协议的控制器，同样，各种传感器、Touch控制器、指纹模块、蓝牙模块、WIFI模块也都兼容这三种通信方式的一种或几种。 下面分别说下： UART UART一般由TXD、RXD、GND三根线组成，是一种 ...

Are you unable to use your touchpad, biometric, touchscreen, or any other interactive on your PC? If the I2C HID Device Driver is not working on Lenovo, Dell, Acer, ASUS, etc laptop, then follow this ...

很多人不知道怎么看着时序图写程序，下面结合一个非标准的I2C器件，教大家如何写一个高效的IO模拟I2C时序。 观察该时序，具备I2C的开始信号，I2C的结束信号，I2C的应答、非应答、响应应答，以及写字节和读字节的基本操作时序。 下面，我们一步一步分析。

Metro smart automated systems always look cool to us. You can scan and rescan to travel just using a MetroCard. No need for special personnel or anything—just ...
