標題: 請教大神：GY-VL53L0X激光模塊ARDUINO源碼串口輸出數(shù)據(jù)的意義？
GY-VL53L0X激光模塊

在串口輸出一下數(shù)據(jù)：
----- START TEST ----
Revision ID: 16
Device ID: 238
PRE_RANGE_CONFIG_VCSEL_PERIOD=7
decode: 16
FINAL_RANGE_CONFIG_VCSEL_PERIOD=5
decode: 12
ready
ambient count: 30
signal count: 569
distance 1800
status: 11
----- END TEST ----

其中distance 指的應(yīng)該是距離，請教各位大神：其它量“ambient coun”、“signal count”、“status”、” decode“指的是什么？

附Arduino源碼：

請問，你的問題得到解決了么？最近也在搞這個，現(xiàn)在我測得的距離不太對，distance在距離近時直接變成20，status也在11和8之間跳。。。。。沒法用啊

您好，我想請教一下，這款傳感器的x和G接口需要接嗎還有是直接用帶的針插進去就可以了么

作者: 9584984k 時間: 2017-10-7 16:44
您好，我也想問一些，這些引腳是怎么連的。我的串口輸出不了這些數(shù)據(jù)

作者: czl8612120 時間: 2017-11-6 20:48
兄弟，你會濾波嗎 QQ390643675
留下你的聯(lián)系方式行嗎

作者: cciew 時間: 2018-3-7 22:29
是這款模塊嗎？注意PS這個針腳，接地是IIC模式，不接地是串口模式！
