ESP32使用PCF8563时钟模块进行网络校时(用到 I2C_BM8563 库) PCF8563 是PHILIPS 公司推出的一款工业级内含I2C总线接口功能的具有极低功耗的多功能时钟/日历芯片。PCF8563 的多种报警功能、定时器功能、时钟输出功能以及中断输出功能能完成各种复杂的定时服务,甚至可为单片机提供看门狗功能。是一款性价比极高的时钟芯片,它...
ESP32的I2C控制器可以工作于Master 模式或者Slave 模式,我们这里只以Master模式为例。 上图为ESP32 I2C Master模式的基本架构,包含了32X8 Bit的RAM,16 个命令寄存器(cmd0 ~ cmd15) 以及一个CMD_Controller,2个总线控制器,2个总线滤波器以及一个数据移位寄存器。 看起来挺复杂的样子,其实实际操作起来,只有命令寄...

ESP32 I2C Default Pins As we’ve stated earlier in this series of tutorials, all ESP32 peripherals are interconnected together internally via a GPIO Matrix and you’ve got also a GPIO Mux. This enables you, the user (programmer), to route any peripheral signal to any GPIO pin. But, by...
