LIS2DH12始终仅在spi的接收缓冲区中返回0x80,0x40,0xC0值

要检查SPI通信，首先尝试读取who_am_i（0x0F）寄存器，如果它工作，则尝试将值写入寄存器并将其读回。
如果这样做，请分享您的传感器配置，我可以检查它。



以下为原文




To check your SPI communication first try to read who_am_i (0x0F) register, if it works then try to write a value to a register and read it back.
If this works, please share you sensor configuration and I can check it.

感谢您的关注，我能够从WHO_M_I寄存器读取值0x33，并能够从任何寄存器进行写入和读取。
这是我的MEMS配置功能：
void MCAL_MEMS_Init（）
{
 
 int i;
 / * MEMS配置寄存器* / LIS2DH12_Write（LIS2DH12_REG_CTRL_REG1,0x77）;
 
 对于（I = 0; I＆LT; 100;我++）;
LIS2DH12_Write（LIS2DH12_REG_CTRL_REG2,0x00）;
 对于（I = 0; I＆LT; 100;我++）;
LIS2DH12_Write（LIS2DH12_REG_CTRL_REG4,0x00）;
 对于（I = 0; I＆LT; 100;我++）;
LIS2DH12_Write（LIS2DH12_REG_CTRL_REG5,0x00）;
 对于（I = 0; I＆LT; 100;我++）;
LIS2DH12_Write（FIFO_CTRL_REG，0x00）;
 对于（I = 0; I＆LT; 100;我++）;
LIS2DH12_Write（TEMP_CFG_REG，0x00）;
 对于（I = 0; I＆LT; 100;我++）;
LIS2DH12_Write（INT1_CFG，0x00）;
 对于（I = 0; I＆LT; 100;我++）;
如果我在配置MEMS寄存器时做错了，请建议我。

Thanks for your attention and I am able to read value 0x33 from WHO_M_I register as well as able to write and read from any register.
This are my MEMS configuration function:
void MCAL_MEMS_Init()
{

int i;
/* MEMS Configuration Register */LIS2DH12_Write( LIS2DH12_REG_CTRL_REG1,0x77);

for(i=0;i<100;i++);
LIS2DH12_Write( LIS2DH12_REG_CTRL_REG2,0x00);  
for(i=0;i<100;i++);
LIS2DH12_Write( LIS2DH12_REG_CTRL_REG4,0x00);  
for(i=0;i<100;i++);
LIS2DH12_Write( LIS2DH12_REG_CTRL_REG5,0x00);  
for(i=0;i<100;i++);
LIS2DH12_Write( FIFO_CTRL_REG ,0x00);  
for(i=0;i<100;i++);
LIS2DH12_Write( TEMP_CFG_REG ,0x00);  
for(i=0;i<100;i++);  
LIS2DH12_Write( INT1_CFG ,0x00);  
for(i=0;i<100;i++);
}Please suggest me if i am doing anything wrong in configuring MEMS registers.

你配置正确，只设置CTRL_REG1足以使传感器工作，其他寄存器都是默认值。
您确定要读取正确的输出寄存器吗？您写道，您在所有六个寄存器中读取了3个值（0x80,0x40,0xC0），这没有多大意义。所有六个寄存器的值是多少？他们稳定吗？



以下为原文




You configuration is correct, only set the CTRL_REG1 is enough to make the sensor work, other registers are in default value.
Are you sure you you are reading the correct output registers. You wrote that you read 3 values (0x80, 0x40, 0xC0) in all six registers, it doesn't make much sense. What are the values in all six registers? Are they stable?

再次感谢您的关注和测试目的，如果我只检查一个寄存器，假设OUT_X_L或任何其他它将返回那些不正确的值（0x80,0x40,0xc0）我猜，我想要得到变量而不是修复值这些寄存器在传感器的运动上。
如果你能说出来，可能是什么原因。



以下为原文




Thanks for your attention again and for testing purpose if i check only one register suppose OUT_X_L or any other it will return those values(0x80,0x40,0xc0) which is not right i guess, i am suppose to get variable and not fix values in these registers on movement of the sensor.
What could be the possible reason if u can tell.

不幸的是，你的解释并不清楚。我认为，传感器工作，你只是误解了结果。
请读取所有六个输出寄存器（在移动期间或在不同的传感器位置）并共享值，然后我可以检查它。



以下为原文




Unfortunately, your explanation is not clear. I think, the sensors works, you only misinterpret the results.
Please read all six output registers (during movement or in different sensor position) and share the values, I can then check it.
