Vl53L0X测距传感器如何通过GPIO中断

问答对人有帮助，内容完整，我也想知道答案 0 喜 Vl53L0X测距传感器如何通过GPIO中断中断，我只能在vl53l0x_interrupt_threshold_settings.h中找到很长的寄存器地址列表。在初始化和校准传感器之后，我尝试使用下面的代码。但是，StartMeasurement（）中没有给出中断。我正在使用STM32f103RE微控制器。 FixPoint1616_t threshold_high =（255）; FixPoint1616_t threshold_low =（350）; status = VL53L0X_SetInterruptThresholds（pTestDev， VL53L0X_DEVICEMODE_SINGLE_RANGING，threshold_low， threshold_high）; status = VL53L0X_SetGpioConfig（pTestDev，0，VL53L0X_DEVICEMODE_SINGLE_RANGING，VL53L0X_GPIOFU NCTIONALITY_THRESHOLD_CROSSED_LOW，VL53L0X_INTERRUPTPOLARITY_LOW）;状态= VL53L0X_StartMeasurement（pTestDev）; 最好的祝福乔纳斯 #interrupt＃vl53l0x＃stm32f103＃interrupt-status-register 以上来自于谷歌翻译以下为原文 hi, how does the Vl53L0X ranging sensor adress the GPIO for the interrupt, i can only find a long list of register adresses in the vl53l0x_interrupt_threshold_settings.h. After initialization and calibration of the Sensor, i tried it with the code below. However, no interrupt is given out in StartMeasurement(). Im using the stm32f103RE microcontroller. FixPoint1616_t threshold_high=(255); FixPoint1616_t threshold_low=(350); status= VL53L0X_SetInterruptThresholds(pTestDev, VL53L0X_DEVICEMODE_SINGLE_RANGING, threshold_low , threshold_high); status=VL53L0X_SetGpioConfig(pTestDev,0,VL53L0X_DEVICEMODE_SINGLE_RANGING,VL53L0X_GPIOFU NCTIONALITY_THRESHOLD_CROSSED_LOW, VL53L0X_INTERRUPTPOLARITY_LOW); status=VL53L0X_StartMeasurement(pTestDev); best regards jonas #interrupt #vl53l0x #stm32f103 #interrupt-status-register 0

答案对人有帮助，有参考价值 0 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！以上来自于谷歌翻译以下为原文 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!

答案对人有帮助，有参考价值 0 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。以上来自于谷歌翻译以下为原文 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.
