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, ...

Nowadays there are many hardware communications protocols to choose from, UART, SPI, I2C three protocols are the most representative, they are widely used. They have different characteristics, and how ...

Experimental This library gives easy control over the 8 pins of a TCA9554 and TCA9534 device. The pins can be used for INPUT (default) and OUTPUT, and can be set per single pin, or with a mask to set ...

The Arduino ecosystem is an amazing learning tool, but even those of us who love it admit that even the simplified C Arduino ...

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。
