LIS2DH12测量转换如何解析数据？

当我尝试从传感器获取数据时，我遇到了一些问题。我可以读取寄存器并获取一些数据，但我不知道我应该怎么做才能获得真正的价值。
我正在使用arduino，我发现了一些库。这些库倾向于使用这种格式：


x =（（int8_t）sensorData [1]）* 256 + sensorData [0];
y =（（int8_t）sensorData [3]）* 256 + sensorData [2];
z =（（int8_t）sensorData [5]）* 256 + sensorData [4];其中sensorData的位置0在OUT_X_L（28h）处开始并且向上。
这是正确的吗？我已经阅读了关于LSB左对齐的内容，我认为它应该是这样的：
它是一样的吗？
除此之外，他们使用公式从x，y和z值中获取mg值：
x =（int32_t）x * 1000 /（1024 * mgScaleVel）; //将数据转换为毫克，2g刻度轴* 1000 /（1024 * 16），

y =（int32_t）y * 1000 /（1024 * mgScaleVel）; //对于4g刻度轴* 1000 /（1024 * 8），
z =（int32_t）z * 1000 /（1024 * mgScaleVel）; //对于8g刻度轴* 1000 /（1024 * 4）这是关于什么的？这个公式出现在哪里？这是对的吗？我该如何解析数据？

I am having some problems when I try to get data from my sensor. I can read registers and get some data but I don't know how I should do the covnersion to get a real value.
I am using an arduino and I found some libraries. Those libraries tend to use this format:

  
x = ((int8_t)sensorData[1])*256+sensorData[0];
y = ((int8_t)sensorData[3])*256+sensorData[2];
z = ((int8_t)sensorData[5])*256+sensorData[4];Where position 0 of sensorData starts at OUT_X_L (28h) and goes up.
Is this right? I have read something about left justified of LSB and I think it should be like:
Is it the same?
Apart from that, they use a formula to get mg values from the x,y and z values:
x = (int32_t)x*1000/(1024*mgScaleVel); //transform data to millig, for 2g scale axis*1000/(1024*16),

y = (int32_t)y*1000/(1024*mgScaleVel); //for 4g scale axis*1000/(1024*8),
z = (int32_t)z*1000/(1024*mgScaleVel); //for 8g scale axis*1000/(1024*4)What is this about? where does this formula appear? Is it correct? How should I parse the data?
