in blocking mode 与n no-blocking mode有啥区别？
HAL_I2C_Master_Transmit与HAL_I2C_Master_Transmit_IT一个是在blocking模式一个是在no-blocking 模式
阻塞模式和非阻塞模式...... 我的理解是: 阻塞模式就像是一个延时函数,当这个函数没处理完那么,所有的按照流程需要执行的代码都不会被执行,要等到这个延时完成,类似 平时看书上写的LED灯闪烁,用的delay()一样.. 而非阻塞模式就像他定义的那样,一般用的是中断,执行这条语句的时候,开启相应的中断达到一定的条件才进行处理,这样不会影响到流程的执行. 我的理解就是,阻塞就是死等,非阻塞就是中断
可以参考
