LSM6DS3数据就绪中断

嗨，我面临着在INT1上获得数据就绪中断的问题。
使用I2C通信。
试图让fifo工作并坚持下去，所以从数据就绪开始。
根据应用说明：
1写入CTRL9_XL = 38h //启用Acc X，Y，Z轴

2写CTRL1_XL = 60h // Acc = 416Hz（高性能模式）
3写入INT1_CTRL = 01h // INT1上的Acc数据就绪中断初始化3个寄存器，并尝试根据应用笔记中的第4.2章从INT1读取中断数据。
如果我在中断中读取STATUS_REG，那么我在繁忙状态下卡在HAL_I2C_Mem_Read函数内。
如果我在我的主要读取它（1）然后它开始工作，但以一种奇怪的方式产生中断（图片附加。）
我读：
1阅读状态

2如果XLDA = 0，则转到1
3读取OUTX_L_XL
4读取OUTX_H_XL
5阅读OUTY_L_XL
6阅读OUTY_H_XL
7阅读OUTZ_L_XL
8在我的中断中读取OUTZ_H_XLI切换输出引脚。
当我读
STATUS_REG我看到第一位是1，这意味着acc数据准备就绪。
但无论何时我读它总是1.我在读取它时读取它并且它是1.我从OUTX_L_XL读出后再次读取它，
OUTX_H_XL，
OUTY_L_XL，
OUTY_H_XL，
OUTZ_L_XL，
OUTZ_H_XL它仍然是一个。我从输出寄存器读取的数据始终为0。
我将我的acc改为104赫兹。相同的图片。
如果我不读，我不会看到任何中断。
所以第一个问题是读取中断回调内的数据。 （但我可以在主要内容中阅读）。陷入I2C，我无法解释当我试图在内部或外部读取i2C时有什么区别。
第二个原因是中断在不同的时间进入，数据总是为0。
ps：如果我的INT_1 = 0，我可以从acc检索数据，并且我从OUTX_L_XL读取。

Hi, I`m facing a problem to get data ready interrupt on INT1.
Use I2C communication.
Trying to make fifo work and stuck with that, so started from data ready.
According to Application notes :
1 Write CTRL9_XL = 38h // Acc X, Y, Z axes enabled

2 Write CTRL1_XL = 60h // Acc = 416Hz (High-Performance mode)
3 Write INT1_CTRL = 01h // Acc Data Ready interrupt on INT1Initialize 3 registers and try to read data in interrupt from INT1 according to chapter 4.2 in application notes.
If i read STATUS_REG in interrupt then i stuck inside HAL_I2C_Mem_Read function in busy state.
If I read it in my main while(1) then it start working, but interrupt generated in a strange way (picture attached.)
I read:
1 Read STATUS

2 If XLDA = 0, then go to 1
3 Read OUTX_L_XL
4 Read OUTX_H_XL
5 Read OUTY_L_XL
6 Read OUTY_H_XL
7 Read OUTZ_L_XL
8 Read OUTZ_H_XLI toggle output pin in my interrupt.
When i read
STATUS_REG i see that the first bit is 1, which mean acc data is ready.

But no matter when i read it it is always 1. I read it when interrupt take a place and it is 1. I read it again after reading out from OUTX_L_XL,
OUTX_H_XL,
OUTY_L_XL,
OUTY_H_XL,
OUTZ_L_XL,
OUTZ_H_XL it is still one. Data that i read from output registers is always 0.


I change my acc to be 104 hz. Same picture.


If i don`t read  than i don`t see any interrupts coming.


So first problem is to read data inside interrupt callback. (but i can read it in main). Stuck in I2C, i cannot explain what the difference when i trying to read i2C inside interrupt or outside.


Second why interrupts are coming in different timing and data is always 0.


ps: I can retrieve data from acc if my INT_1 = 0, and i read from OUTX_L_XL.
