PSOC BLE-4和MPU-6050之间的I2C通信错误

每个I2C API返回一个可以分析的状态。返回值！= 0表示一个错误，在适当的.h文件中发现的描述。
一些.h文件丢失，因此编译器很难找到声明和定义。
鲍勃



以下为原文
Every I2C API returns a status which you can analyze. Values returned != 0 indicate an error, description found in the appropriate .h file.
Some .h files are missing, so it is difficult to have the compiler find declarations and definitions.

鲍勃，
谢谢你的回复。
MpU6050库包含在项目中，所以我不确定哪一个.h文件丢失。代码编译并在UART上打印数字。只是这些读数在MPU6050中是不可用的。
在我下载文件的页面上，您回答了I2C API改变了。塞巴斯蒂安后来用下面的代码修改了那部分：

恐怕这部分代码会影响阅读部分。你能帮帮我吗？
最好的，

Bob,

Thanks for replying.
The MPU6050 library is included in the project-- so i am not sure which .h files are missing. The code compiles, and prints numbers on the UART. Just that readings are not available the MPU6050.

On the page from where I downloaded the file, you had replied that i2c API changed. Sebastian later modified that part with the following piece of the code:

=============================old code===========================================
void I2CReadBytes(uint8_t devAddr, uint8_t regAddr, uint8_t length, uint8_t *value) {
uint8_t i=0;
I2C_MPU6050_I2CMasterSendStart(devAddr, I2C_MPU6050_I2C_WRITE_XFER_MODE);
I2C_MPU6050_I2CMasterWriteByte(regAddr);
I2C_MPU6050_I2CMasterSendRestart(devAddr, I2C_MPU6050_I2C_READ_XFER_MODE);
while (i++ < (length-1)) {
*value++ = I2C_MPU6050_I2CMasterReadByte(I2C_MPU6050_I2C_ACK_DATA);
}
*value = I2C_MPU6050_I2CMasterReadByte(I2C_MPU6050_I2C_NAK_DATA);
I2C_MPU6050_I2CMasterSendStop();
}

=============================new code===========================================
void I2CReadBytes(uint8_t devAddr, uint8_t regAddr, uint8_t length, uint8_t *value) {
uint8_t i=0;
I2C_MPU6050_I2CMasterSendStart(devAddr, I2C_MPU6050_I2C_WRITE_XFER_MODE,0);
I2C_MPU6050_I2CMasterWriteByte(regAddr,0);
I2C_MPU6050_I2CMasterSendRestart(devAddr, I2C_MPU6050_I2C_READ_XFER_MODE,0);
while (i++ < (length-1)) {
I2C_MPU6050_I2CMasterReadByte(I2C_MPU6050_I2C_ACK_DATA,value++,0);
}
I2C_MPU6050_I2CMasterReadByte(I2C_MPU6050_I2C_NAK_DATA,value,0);
I2C_MPU6050_I2CMasterSendStop(0);
}

===============================================================================

I am afraid that this the part of the code that is affecting the reading part. Could you please help me?

Best,
Apoorva

你好，
请从第三方博客测试这个特定代码。
山姆的博客：从MPU-6050获得滚动、俯仰和偏航
这只能与旧版本的创建者一起工作。首先，如果项目在老版本的创建者中工作得很好，这样我们就可以确认它不是一个硬件问题。
谢谢，
希马



以下为原文
Hello,

Kindly test this particular code from a third party blog.

Sam's Blog : Getting Roll, Pitch and Yaw from MPU-6050

This would work only with old version of Creator. First try if the project is working fine in the older version of Creator so that we can confirm its not a hardware issue.

Thanks,
Hima

谢谢，Hima。实际上，这是旧代码，I2C协议从那时起就发生了变化。PSoC4.1在编译此代码时抛出错误。
我发现了错误的原因。SCL和SDA之间的上拉电阻没有被正确地连接，这就是通信被卡住了。
最好的，
阿波奥瓦



以下为原文
Thanks, Hima. Actually, this is the old code, and i2c protocol has changed since then. PSOC4.1 throws error while compiling this code.

I found the reason for the error. The pull-up resistance between SCL and SDA wasn't connected properly, which was communication was stuck.

Best,
Apoorva

简单解XD
有时很难找到错误和问题…
