Hello, the creation of a Clocking Wizard instance in Vivado 2014.4 fails with ERROR: [ #UNDEF] conversion to double from string is failed unexpected "," outside func
differential. So I simply used the Camera Link Receiver template of the SelectIO Interface Wizard ...

USRCLK以及USRCLK2必须成双成对,由之前讲到的TXUSERCK以及TXUSRCLK2,那TX端必须有对应的结构,与对应的时钟RXUSRCLK以及RXUSRCLK2.
在SPI初始化时，你可以按照以下步骤进行配置：1. 禁用SPI模块：`SPIx_CR1 &= ~SPI_CR1_SPE;`2. ...
