VL53L0X测试一

一、编译源码

编译vl53l0x_test.c生成vl53l0x_test，然后将vl53l0x_test上传到硬件终端。

程序中已设定传感器工作在CONTINUOUS_TIMED_RANGING模式。

二、调试

1、测量距离

先执行./vl53l0x_test -o进行校准

# ./vl53l0x_test -o

再执行./vl53l0x_test测量距离

# ./vl53l0x_test

2、测试low mode中断门限模式

例如设置当距离≤300mm时才产生中断，执行./vl53l0x_test -L 300

# ./vl53l0x_test -L 300
Configuring Low threshold = 300, High threhold = 0[ 4009.689413] Call of VL53L0X_DataInit

[ 4009.734288] Call of VL53L0X_StaticInit

^CRange: 265, Error:0, SigRate_mcps: 202240, AmbRate_mcps:  13824

只有当300mm内有物体时才会输出距离。
