i2cSlave_define.v注释: SDA should have a minimum of 100ns of set up time, with respect to SCL rising edge. But with the very slow edge speeds used in I2C it is better to err on the side of caution. i2cSlave.v注释: Because sda hold time from scl falling is 0ns, sda must be de...

对于IIC从机C文件，首先清除其他中断，允许仅SDA中断。当接收到起始信号后，程序开始进入通信流程。处理通信状态，通过SDA的起始和停止信号判断通信进行状态。引入超时机制用于处理异常，避免通信堵塞。在调用函数时，应避免同时使用延时操作占用处理时间。通信速率设置较低，确保稳定性。超时机制的实现需根据时钟...
