SCL和SDA不可以直接接到TX和RX上。以下是具体原因: 一、接口定义与功能 SCL与SDA: SCL(Serial Clock):串行时钟线,负责产生同步时钟脉冲。 SDA(Serial Data):串行数据线,负责在设备间传输串行数据。 这两根线通常用于I2C(Inter-Integrated Circuit)总线通信,是一种同步、半双工双向的两线
双向数据通道。该两组数据是通过双向数据通道，来进行接收的。数据是事实或观察的结果，是对客观事物的逻辑归纳，是用于表示客观事物的未经加工的的原始素材。
msp430 g2553 硬件I2C配置完之后,SDA与SCL电平不变化Canming Huang Prodigy 31 points 参考了官方的例程,用官方的例程结合逻辑分析仪,可以看到明显的I2C开始波形、传递字节波形 但是我按照需要将其分为几个函数之后,SDA线和SCL线就一动不动了,SDA一直是低电平,SCL一直是高电平 请问这是什么问题? 我看了下官方...

问AXI IIC总线: SDA上没有数据波形ENI2C(IIC)属于两线式串行总线，由飞利浦公司开发用于微控制器(MCU)和外围设备(从设备)进行通信的一种总线，属于一主多从(一个主设备(Master)，多个从设备(Slave))的总线结构，总线上的每个设备都有一个特定的设备地址，以区分同一I2C总线上的其他设备。
Note that on the first few pulses, neither the SCL or SDA pins are pulled close enough to ground for the FRAM to recognize them. The PSoC 6 I2C component is configured as a master at 400 kbps with TX and RX FIFO. Both SCL and SDA pins are configured as bidirectional with Open ...
