写了个模拟I2C的代码,由于管脚复用其他功能,所以每次调用初始化GPIO保证状态,但是发现经常性的CLK不发数据。后来发现是因为GPIO_InitStruct.Speed = GPIO_SPEED_FREQ_HIGH;没写。为什么不写速度会导致初始化异常呢,关键信息不是pin,mode就够了?初学者求大神赐教GPIO_InitStruct.Pin = I2C_SDA_01_Pin;GPIO_InitStr...
一种高速ADC接口与GPIO接口相互测试的方法,在SOC上,选择8个GPIO口模拟数据线,1个GPIO口模拟时钟线,通过GPIO口不断循环的送出0x1,0x2,0x4,0x8,0x10,0x20,0x40,0x80这8组数据,给HS-ADC的clkin同时灌clk,在每个时钟的上升沿采集数据. A method of high-speed ADC interface GPIO interface testing each ...
