GPIO_InitStructure.GPIO_Speed = GPIO_Speed_100MHz; 跳转过去可以看到都有多少Hz的速度 底下是宏定义 2MHz Low_Speed 低速 25MHz Medium_Speed 中速 50MHz Fast_Speed 快速 100MHz High_Speed 高速 GPIO初始化 带Init后缀的全是初始化函数,这里是初始化GPIO G族的引脚。 GPIO_Init(GPIOG, &GPIO_InitStructure...
The standard clock (SCL) speed for I2C up to 100KHz. Philips do define faster speeds: Fast mode, which is up to 400KHz and High Speed mode which is up to 3.4MHz. All of our modules are designed to work at up to 100KHz. We have tested our modules up to 1MHz but this needs a...
