Vl53L0X测距传感器如何通过GPIO中断

我现在用民意调查做了。通过高速测量，我猜不会浪费太多时间。我会把它装进去以后再打断。谢谢！

I did it with a poll now. With high speed measurement, there is not much time wasted i guess. I will cange it to interrupt later on. Thanks!

民意调查显示整个测量周期约为40ms。我认为对于我的系统来说，阻塞时间并不重要，因为MC无论如何都会等待结果。
但是，在将测量更改为之后，（）显示错误3.这是最小范围失败并且根据手册UM2039第16页默认情况下甚至没有设置。复位后2秒发生错误，然后在没有任何错误的情况下实现测量。我尝试了一些延迟以获得缓冲区的时间，但这只会延迟到错误的时间。
与您以前的代码不同，我使用轮询完成了所有操作，并没有为中断设计硬件。
古来= HAL_GetTick（）;

/ *要求准备好测量数据并等待40 ms直到数据准备好* / while（（MeasurementDataReady [k]！= 1）＆amp;＆amp;（time＆lt; = 40））{

NEWTIME = HAL_GetTick（）;
时间= NEWTIME-古来;
状态[10] = VL53L0X_GetMeasurementDataReady（）;
}
/ *将测量数据存储在设备上的struct * /
状态[11] = VL53L0X_GetRangingMeasurementData（）;状态[12] = VL53L0X_ClearInterruptMask（）;
编辑：听起来像是一个中断的错误，它是。在解除中断后，测量数据就像它应该的那样。代码正在运行。

The entire measurement cycle is about 40ms now with the poll. I think for my system the blocked time is not critical, cause the MC waits for the result anyway.
However after changing the measurement to , the () shows error 3. Thats Min Range Fail and according to the manual UM2039 page 16 not even set by default. The error occurs 2 seconds after reset, before that the measurement is achieved without any error. I tried some delay to get time for the buffer, but that only delays the time till the error.
In deviation to your previous code, i did everything with a poll and didn't designed the hardware for interrupt.
oldtime=HAL_GetTick();

/*Ask for measurement data ready and wait 40 ms till data is ready */ while ((MeasurementDataReady[k]!=1)&&(time<=40)) {

newtime=HAL_GetTick();
time=newtime-oldtime;
status[10]=VL53L0X_GetMeasurementDataReady();
}
/*Store measurement data in struct on device*/
status[11]=VL53L0X_GetRangingMeasurementData(); status[12]=VL53L0X_ClearInterruptMask();

• Edit: Sounds like an error of an interrupt, and it was. After uncommeting the interrupt, the measurement data is like it is supposed to. The code is working.
