从数组中读取数据

嗨，

我正在开发包含I2C 通信的应用程序，所以我已经实现了AN8231的代码。

到目前为止它工作正常，我在input_buf []中从I2C外设获得数据。数据有效，我可以在调试器会话的监视窗口中看到它们。但是当我尝试使用数据时：
Raw_X_L = input_buf [0];
它始终是0x00，这是无效值（来自监视窗口）。

这是代码：
u8 input_buf [MAX_INPUT]; //接收缓冲区
u8 output_buf [MAX_OUTPUT]; //传输缓冲区
...
...

void Read_M（void）
{
output_buf [0] =（OUT_X_L_M | 0x80）;
while（！I2C_WriteRegister（lsm9ds0_xm_addr，SEV_BIT_ADDRESS，STOP，0x01，＆amp; output_buf [0]））;
while（！I2C_ReadRegister（lsm9ds0_xm_addr，SEV_BIT_ADDRESS，STOP，0x06，＆amp; input_buf [0]））;
}
...
...
Raw_X_L = input_buf [0];

如何将input_buf []中的数据分配给变量？同时我可以从output_buf []中分配值。

最好的祝福，

Hi,

I'm developing applica tion which include I2C communication, so I have implemented code from AN8231.

So far it works fine and I got data from I2C peripheral in input_buf[]. Data are valid, and I can see them in watch window in the debugger session. But when I try to use data ie:
Raw_X_L = input_buf[0];
it is always 0x00 which is not valid value (from watch window).

Here is code:
u8 input_buf[MAX_INPUT]; //receiving buffer
u8 output_buf[MAX_OUTPUT]; //transmitting buffer
...
...

void Read_M (void)
{
output_buf[0] = (OUT_X_L_M | 0x80);
while (!I2C_WriteRegister(lsm9ds0_xm_addr,SEV_BIT_ADDRESS, STOP, 0x01, &output_buf[0]));
while (!I2C_ReadRegister(lsm9ds0_xm_addr, SEV_BIT_ADDRESS, STOP, 0x06, &input_buf[0]));
}
...
...
Raw_X_L = input_buf[0];

How to assign data from input_buf[] to variable? At the same time I can assign value from output_buf[].

Compiler is COSMIC STM8
