PIC24F使用I2C问题与MPU6050连接

嘿，在那里，我有一个问题，我目前的设置，我从MpU6050芯片接收的数据总是相同的。我对这一级别的编程相当陌生，所以我想问一下，如果我错过了一些显而易见的东西。所以我特别使用PIC24FJ128GA204 MCU作为好奇心板的一部分。因此，我使用XC16编译器。我选择使用MCC生成I2C代码，我可以用它与MPU6050加速度表进行接口。我可以看到引脚RB8＝SCL，RB9＝SDA，VCC在DEV板上连接到5V，接地到GND。我可以使用I2C1MyMraveWrror（）来写入I2C设备及其寄存器。我给寄存器写加速度计数据。为了查看返回的数据，我将它保存在一个数组FROMI2C1WAdMaskRead（）中，然后在它的内容后面看到一个断点。因此，我运行这个和甜，数组中填充了一些值，我再次运行循环，同样的数据在那里…我试着改变很多不同的东西。试图写入不同的寄存器（它们似乎都返回相同的数据集，甚至是“我是什么”），并试图在数据表中找到一些配置寄存器。我的第一个想法是使用断点，查找变量可能不是最好的方法。任何帮助都会得到极大的赞赏。请找到下面的相关文件和主文件的源代码。如果有帮助的话，我可以提供整个项目。

    Hey there,

I'm having a problem with my current setup where the data I am receiving from the MPU6050 chip is always the same. I'm fairly new to this level of programming so thought I'd ask here if I am missing something obvious first.

So specifically I am using the PIC24FJ128GA204 MCU as part of the curiosity board. Therefore I am using the XC16 compiler. I chose to use the MCC to generate the I2C code I could use to interface with the MPU6050 accelerometer. I can see the pins RB8 = SCL, RB9 = SDA, the vcc is attached to 5V on the dev board and ground to GND.

From what I understand. I can use the I2C1_MasterWrite() to write to an I2C device and its register. I write to the register for the accelerometer data. To see what data is returned, I hold it in an array from I2C1_MasterRead() and a breakpoint after to look at it's content. So I run this and sweet, the array is populated with some values, I run through the loop again, the same data is there...
I've tried changing a lot of different things. Trying to write to different registers(They all seem to return the same set of data, even the "what am I" register.) and trying to write to some config registers I found in the data sheet.
My first thought is using a breakpoint and looking in the variable might not be the best way to do it?
Any help would be appreciated massively. Please find the relevant documents to me below and the source code of the main file. I can provide the whole project if it would help.
