z - start clock Z - stop clock q - SQW/OUT = 1Hz Q - stop SQW/OUT 该代码将帮助您设置时间以及检查模块的备用电池供电是否正常。在下一个教程中,我将向您展示如何设置LCD显示器并显示RTC模块中的时间。这是用于测试模块及其附件的代码。 #include ...
顾名思义,1-Wire就是采用单一信号线,但可像I2C,SPI一样,同时传输时钟(clock)又传输数据(data),而且数据传输是双向的。1-Wire 使用较低的数据传输速率,通常是用来沟通小型device,如数位温度计。通过1-Wire技术可以在单一信号线的基础上构成传感器网络,Maxim起名”MicroLan”。

Rating: 7Reviews Grove - DS1307 RTC is based on the clock chip DS1307 and supports I2C communication! It uses a Lithium cell battery (CR1225). We choose to use the RTC based on DS1307 as it is low cost and also very energy efficient. It can run for years on a very small coin ce...
