如何实时并以更新的方式读取我在Code Composer Studio中通过I2C和UART发送/接收的内容？

Question

除了使用LabView程序通过UART通讯和图形接收数据外，我还必须做一个项目，其中必须使用Code Composer Studio程序和MSP432微处理器通过I2C读取IMU的数据。它。 问题是我不知道如何使用Code Composer Studio程序太多，尽管代码（如果想查看它，请在下面保留）不会给出任何错误……首先，我不知道在哪里可以看到我正在“理论上”读取的数据，其次...在LabView中，结果是我没有得到任何字节，然后就无法绘制任何图形。

如果有人知道我该如何解决或有任何建议，请回答！谢谢!!!
