为了减少原型期间的线路拥塞，可以将RTC直接插入arduino的模拟引脚。用公头插针焊接SCL、SDA、Vcc和GND，并...
1.电路的电流一般很小,只有当DS18x20进行温度转化或者写EEPROM时会高达1.5mA,当DS18x20进行上述操作时,数据线必须保持电平拉高状态直到操作结束,期间master端的Arduino不能做任何操作,DS18x20温度转化时这个时间间隔大概是750ms。 2.如果要求DS18x20有精确的转化,数据线在温度转化期间必须保证足够的能量,但当你使用多...

Inside the juicy enclosure is an Arduino Nano, an RTC, and a 7-segment display. We love the attention to detail here, from the little green leaves on top to the anatomically-correct dimple on the underside. And we always like to see lids that snap on with magnets. So satisfying. Check...
Introduction The STM32’s integrated RTC (Real-Time Clock) peripheral can be used to periodically wake it up from one of the various Low Power modes.
