4端口操作说明
4.1、功能说明
4.1.1、 总线接口
数据的输入与输出由SDA 和SCL 引脚完成。端口必须接上拉电阻到电源正极。
4.1.2、 数据有效性
当SCL 为高电平时,SDA 数据有效并保持稳定。当SCL 为低电平时,SDA 的高电平和低电平状
态可以改变。可参考下图:
4.1.3、 开始/结束条件
数据开始必须满足:1)SCL 为高电平;2)SDA 从高电平转变为低电平。
数据结束必须满足:1)SCL 为高电平;2)SDA 从低电平转变为高电平。可参考下图:
4.1.4、 数据格式
每个字节由八位组成,每字节必须跟随一个应答信号(第九个字节)。高位首先被传输。
4.1.5、 应答信号
在发送响应信号脉冲时,单片机预置SDA 一个持续的高电平,响应时,电路强制拉低SDA 电平,
这样,SDA 在这个脉冲段中保持低电平。音频处理器在接收到每一个字节数据时都将返回一个应答信
号,否则,SDA 在第九个脉冲期间将保持高电平。此时,单片机将产生一个中断信号来停止发送。可
参考下图:
4.1.6、 无应答信号的数据传输
如果不使用应答信号,有一种简单的单片机传输方式可以使用:等待一个时钟且不检查此时的
