IIS2DH（DM00171283）单击检测？

您的配置是正确的，但您还必须为单击检测设置两个配置寄存器（CLICK_THS，TIME_LIMIT）。
如果设备配置为单击事件检测，则当所选通道上的输入加速度超过设定的阈值CLICK_THS时会产生中断，并在TIME_LIMIT寄存器定义的时间窗口内返回低于此值的中断。



以下为原文




You configuration is correct, but you have to set also two configuration registers for single click detection (CLICK_THS, TIME_LIMIT).
If the device is configured for single-click event detection, an interrupt is generated when the input acceleration on the selected channel exceeds the programmed threshold CLICK_THS, and returns below it within a time window defined by the TIME_LIMIT register.

I2C_WriteByte（安培; click_ths，1,0x0D）;
我已经配置了上面的寄存器并且我连续读取了点击源寄存器但是当我点击加速度计中断生成并且点击来自传感器的源值是从该值得到的0x09,0x01,0x51我认为只有0x51是正确的以匹配唯一的X轴启用检测，而形成另外两个值，我也得到了中断。我的配置是否正确？我还有一个查询，在上面的配置time_limit和
click_ths
寄存器，我加载了0x05和0x0d，这意味着经过多少时间和多少加速后它产生中断？所以，可以帮我解决这个问题。感谢您的支持。

I2C_WriteByte(&ctrl_1,1,0x5F);

I2C_WriteByte(&ctrl_3,1,0x80);
I2C_WriteByte(&ctrl_6,1,0x82);
I2C_WriteByte(&ctrl_4,1,0x00);
I2C_WriteByte(&int1_config,1,0x00);
I2C_WriteByte(&ctrl_5,1,0x40);
I2C_WriteByte(&click_config,1,0x01);//only x axis click enable
I2C_WriteByte(&time_limit,1,0x05);
I2C_WriteByte(&click_ths,1,0x0D);
I have configured above registers and I read click source register continuously but when I click the accelerometer  interrupt is generated and click source values is getting from sensor is  0x09,0x01,0x51 from that value I thought only 0x51 is correct to match with the only X axis enable detection whereas, form the other two values, I had got the interrupt as well. Am I done correct configuration? and I have one more query that in above configuration time_limit and
click_ths
register,I have load with 0x05 and 0x0d that means after how much time and after how much acceleration it generate the interrupt?So, could help me on that issue. Thank you for your support.

Hello,

Since the documents seem pretty similar, I would try to read the theory of operation in them.

‌, is there a similar application note for newer devices?David

Note: the original post contained a large number of threaded conversations and was only able to be migrated to the 9th level

还有一件事我想在数据表中告诉你
的
DM00171283在点击源寄存器中没有像LIR这样的位。那么，如何使用和配置该注册表进行单击检测？此外，我以前的查询仍未得到解答。我点击一下就得到了中断，但我只点击了一次，中断得到了多次。请为此提供适当的指导。



以下为原文





One more thing I would like to tell you that in the datasheet
of
DM00171283 there are no such bit like LIR in the click source register. So, how to use and configure that register for single click detection? Furthermore, my previous query still not be answered. I got the interrupt on single click but  I only click one time, interrupt got multiple time. Please provide proper guidance for that.

感谢您的特别支持。

Moreover, I have used IA bit to mask for interrupt generation, in my code I have continuously read click source register and once IA bit is set I have read x,y, and z axis value and following reading I have got. It is fine or not? Furthermore, sometimes I have got multiple time IA bit set for single click. So, any method to overcome this issue? Now, it is working very fine.

您好Miroslav，我通过使用硬件中断和IA位屏蔽单击了这两种方法。它工作正常。但是，当我使用硬件中断然后一旦中断激活并且我正在读取点击源寄存器，有时它显示如下的值：
点击src 2
 
x轴为-7
y轴是-4
z轴是31
******************
点击src 5a
x轴为-17
y轴是-11

******************
点击src 1
x轴为-28
y轴为-13
z轴是73
******************点击src a
 
x轴为-4
y轴是5
z轴是15
******************所以，在像0x02,0x01,0x0a这样的情况下，IA位为0表示中断未激活，那么硬件中断是如何激活的？我可以同时使用两种条件来检查中断是否有效？防爆。
如果（hw_interrupt_flag）
{
 if（click_source＆amp;（1＆lt;＆lt; 6）
 {
 打印（'单击检测'）;
 }
}
还有一个问题是你告诉我使用软件过滤器来解决多点击检测问题，那么我是如何实现的呢？
感谢您的支持。

Hi Miroslav, I have done single click on both method by using hardware interrupt and IA bit masking. it is working fine. However, when I used hardware interrupt then once interrupt is active and I am reading click source register, sometimes it is shown value like below:
click src 2

x axis is -7
y axis is -4
z axis is 31
******************
click src 5a
x axis is -17
y axis is -11
z axis is 45
******************
click src 1
x axis is -28
y axis is -13
z axis is 73
******************click src a

x axis is -4
y axis is 5
z axis is 15
******************So, in the case like 0x02,0x01,0x0a IA bit is 0 means that interrupt is not active then how the hardware interrupt is activated? Can I use both condition to check interrupt is active or not? Ex.
if(hw_interrupt_flag)
{
   if(click_source & (1<<6)
   {
         print('single click detect');
   }
}
One more concern is you told that multiple click detection issue is solved by using software filter so, how I achieve it?
Thanks for your support.
