MSP432P401R: I2C

Part Number: MSP432P401R

使用ccs中的教程，，msp432P401R的I2C时钟信号没有输出波形

Susan Yang：

请问您现在硬件使用的是什么？使用的TI的launchpad还是自己的板子？另外是否有接I2C的从机？I2C的上拉电阻是否有接？

请您先详细说明一下情况，谢谢

,

weixiang shen：

我使用的时TI的launchpad的，接有I2C从机，这个从机是一个0.96寸的OLED屏，然后出现的问题就是向OLED屏写数据都会出现NK，用示波器测量端口输出波形只有噪声。将官网的代码烧入板子也是这个样子。

,

weixiang shen：

对了，还忘了说了，我使用的TI的sdk开发，例程也sdk中的例程。

,

Susan Yang：

weixiang shen 说：例程也sdk中的例程。

请问您使用的是哪个例程呢？0.96寸的OLED屏的话，特定从机您需要自己来修改例程中的代码

另外一般I2C总线是需要接上拉电阻的

若是可以的话，请给出您的硬件连接图的照片以及示波器的截图，谢谢

图片上可能看不清楚，单片机的P1.6连接OLED的SDA接口，P1.7连接OLED的SCL接口,程序测试的就是出现一个EUSCI_B_I2C_NAK_INTERRUPT的中断，但是这个OLED是没有问题的，我用STM32测试了一下是能够显示的。那个OLED的SCL和SDA都内部有一个4.7K的上拉电阻。
