std_logic_arith.rar_std_logic_arith
这个错误的意思是在spi_sensor.vhd文件的第41行,接口对象"data"的模式为输出(out),但是该对象又被尝试读取。应该将该对象的模式改为缓存(buffer)。请检查代码并将"data"对象的模式改为缓存(buffer)。例如:
```
signal data : std_logic_vector(7 downto 0);
...
data : out std_logic_vector(7 downto 0)
```
应该改为:
```
signal data : std_logic_vector(7 downto 0);
...
data : buffer std_logic_vector(7 downto 0)
```
