LSM303电子罗盘测试结果 [复制链接]

找到一个STM32F051的板子，发现板子基本的调试都忘光了，熟悉了半天开发板，先把数据读出来再说。串口返回数据如下，
参考其他的例程，先设置几个参数（具体的参数都打印出来了），语文是没学好，都不知道该说些什么了，用过的朋友帮忙看下结果是否正确，传感器板子放在桌子上不动，返回的如下结果。

看这个更像是加速度的数据

您说的对，我读磁场的值都是0，不知道是那里出问题了。

加速度至少读出来了，一样的函数，只是地址不同一个是0x32一个0x3C
读的时候都正确返回了，可是磁场却一直是0
G_response = GetAccAxesRaw(&L_data);
   if(G_response==MEMS_SUCCESS){
printf("AXIS_X value is %d \r\n",L_data.AXIS_X);
printf("AXIS_Y value is %d \r\n",L_data.AXIS_Y);
printf("AXIS_Z value is %d \r\n\r\n",L_data.AXIS_Z);


   }
   G_response = GetMagAxesRaw(&L_dataM);
       if(G_response==1){
printf("MAG_AXIS_X value is %d \r\n",L_dataM.AXIS_X);
printf("MAG_AXIS_Y value is %d \r\n",L_dataM.AXIS_Y);
printf("MAG_AXIS_Z value is %d \r\n\r\n",L_dataM.AXIS_Z);

这个芯片还有温度传感器的功能，读出的温度是25度
手机里显示的当前温度是26度，也算是正确，只有磁场是0，这个是怎么回事呢？

非常感谢您的回复，我太想当然的去考虑问题了，两个型号虽然貌似差别不大，但是，寄存器的地址是不一样的。找了半天也没找到LSM303AGR的例程。之前以为测试就是跑跑现成的，看来这次不行了，其他小伙伴注意了，别犯我的错哦！

非常感谢您的如此详细的细心的答复，本想尽快有了结果给您回复，可是，遇到点挫折，我尝试下载，开始总是到下载界面就没有了，注册了不行，又单独申请下载链接，折腾好几次，最终发现申请两次连接，第二次的下载连接才能用，总算是下载成功了，可是，我用的是051的discovery板，没找到合适的工程，拿来驱动没法直接用，折腾半天最终还是回答自己修改寄存器地址去了，
现在总算是有了结果，磁场的数据挺稳定

LPS22HB 你先对比一下官方例程，看看他们是怎么配置的
然后读一下 WHO AM I看看通信是否正常

LPS22HB 的ID 我读取是正确的，datasheet里的值是0xb1也就是10进制的177
LPS22HB DeviceID  is 177

LSM303AGR的ID 我读取也是正确的，datasheet里的值是0x33也就是10进制的51
LSM303AGR DeviceID  is 51
现在的问题是我读取LSM33agr的温度不对，STATUS_REG_AUX_A (07h)的值应该是0x44，读取正常，
最终读取温度的时候，TEMP_OUT_H_M的值一直是0，导致输出温度是25度，TEMP_OUT_H_M的地址是0x0D，这些都核对过了。
The LSM303AGR is supplied with an internal temperature sensor. Temperature data can be
enabled by setting the TEMP_EN[1:0] bits to ‘1’ in the TEMP_CFG_REG_A (1Fh) register.
To retrieve the temperature sensor data the BDU bit in CTRL_REG4_A (23h) must be set
to ‘1’.
Both the OUT_TEMP_L_A (0Ch), OUT_TEMP_H_A (0Dh) registers must be read.
Temperature data is stored inside OUT_TEMP_H as two’s complement data in 8-bit format
left-justified.
status_t GetTempRaw(i16_t* val) {
  u8_t valueH;

valueH=SetTemperature(MEMS_ENABLE);

if( !ReadReg(ACC_I2C_ADDRESS, TEMP_OUT_L_M, &valueH) )
   return MEMS_ERROR;

//KLS lsm303agr
  if( !ReadReg(ACC_I2C_ADDRESS, TEMP_OUT_H_M, &valueH) )
   return MEMS_ERROR;
  if(valueH & 0x80){
valueH &= 0x7F;
valueH = 0x7F - valueH;
*val = 25 - (i16_t)(valueH);
  } else {
    *val = 25 + (i16_t)(valueH);
  }
  return MEMS_SUCCESS;
