配置似乎对我来说，它按预期工作。如果任何轴的加速度超过2.3g，则将传感器配置为生成中断。
你如何刺激中断？
如果你说：'我读取并处理X，Y，Z寄存器但值总是（或差不多）相同：-20，-3，-6。 LSB或g中的值是多少？
你想达到什么目的？你的目标应用是什么？



以下为原文




The configuration seems OK to me, it works as expected. You configured the sensor to generate the interrupt if acceleration in any axis is above 2.3g.
How do you stimulate the interrupt?

If you say: 'I read and process the X,Y,Z registers but the values are always (or almost nearly)  the same: -20, -3, -6.' are the values in LSB or in g?

What do you want to achieve? What is your target application?

嗨，
感谢您抽出时间来查看并回复。首先也是最重要的是，您能否告知从原始数据到值的转换是否正确？它们应该从原始值转换为“g”值。 （关于你关于LSB或g值的问题）
关于你的另一个问题 - 如果价值几乎总是'
-20，-3，-6。'
那对你来说不是很可疑吗？我感兴趣的是+/- 3g到+/- 100g的值。该应用程序位于工业机器的PCB上，其中存在各种可能达到100g的振动值。那么为什么总会产生这些价值？问候......



以下为原文




Hi,
Thanks for taking the time to look at this and reply. First and most importantly, can you please advise if the conversions from raw data to values look correct? They should be converting from raw values to 'g' values. (in reference to your question about LSB or g values)
With respect to your other question - if the values were almost always '
-20, -3, -6.'
, wouldn't that look suspicious to you? I am interested in those values from +/-3g to +/-100g. The application is on a PCB in an industrial machine and there are all kinds of shake values in there that could potentially go to 100g. So why would it always produce these values?Regards...

好的，如果您可以检查并验证这一点，我将不胜感激 - 它可能是某些问题所在。
此外，值xF，yF和zF已经声明为int8_t。这是你所指的变量（'你可以简单地将类型从uint8_t改为int8_t ......'）或者你的意思是什么不同？



以下为原文




Ok, if you could check and verify this, I would be grateful - it may be where some of the problem is.
Also, values xF, yF and zF are declared as int8_t already. Is that the variables you were referring to ('you can simply change the type from uint8_t to int8_t ...') or did you mean something different?

乍一看，我认为这是不正确的，但我明天会模拟你的代码。
您不必通过如此复杂的函数转换原始值，您只需将类型从uint8_t更改为int8_t并乘以灵敏度即可。
xF =（int_8）x * 0.780f;



以下为原文




At the first glance, I think it is not correct, but I will simulate exactly your code tomorrow.
You don't have to convert the raw value by so complex function, you can simply change the type from uint8_t to int8_t and multiply by sensitivity.

xF = (int_8)x * 0.780f;

这个：
x =（x ^ 0xFF）+ 1; //两个补码
修复。这是胡说八道！
谢谢



以下为原文





This:

x = (x ^ 0xFF) + 1; // Two's complement

Fixed it. It was nonsense!

Thanks

if（x＆amp; 0x80）
 
 
 {
 
 //它是否定的，反转结果
 
 accVal = x ^ 1;
 
 accVal + = 0x1;
 
 cX =（accVal * 0.780）;
 
 // printf（' - X acc value =％。1f  n'，cX）;
 
 }
什么是XOR ONE废话？
if（x＆amp; 0x80）
x =（x ^ 0xFF）+ 1; //两个补码
或者它是符号幅度格式？



以下为原文





  if( x & 0x80 )


        {

            //it's negative, invert result

            accVal = x ^ 1;

            accVal += 0x1;

            cX = (accVal * 0.780);

            //printf('-X acc value = %.1fn', cX);

        }

What's the XOR ONE nonsense?

if (x & 0x80)

x = (x ^ 0xFF) + 1; // Two's complement

Or is it in sign-magnitude format?

我有几个笔记：
- 是的，XOR操作不正确
- 如果您修复XOR操作，转换将是正确的，除了符号。您正在反转该值。如果加速度计输出为正，则得到负值，反之亦然。但也许你是故意这样做的。
- 由于从float转换为int（在此命令中），您正在失去一些精度
xF =（int8_t）cX;）
- 由于C对有符号变量使用二进制补码，您只需用一个命令替换整个if结构：xF =（int8_t）x * 0.780f;



以下为原文




I have several notes:
- yes, the XOR operation was not correct
- if you fix the XOR operation the conversion will be correct except the sign. You are inverting the value. If the accelerometer output is positive you get negative value and vice versa. But maybe you are doing this intentionally.
- you are loosing some precision due to conversion from float to int (in this command
xF = (int8_t)cX;)
- As C use two's complement for signed variables you can simply replace the whole if structure by one command: xF = (int8_t)x * 0.780f;

米罗斯拉夫，
一切都很好，更新了我的代码，结果很好。非常感谢你的帮助！
