Aim: Read Data From Four VL53L0X (TOF) sensor using I2C2(P9_19, P9_20) using c language on BeagleBone Black Board.

I got the data from single VL53L0X sensor data. when this thing I implement with a four-VL53L0X sensor then issues are generated. because all Four Vl53L0X have same I2C_Slave_address = 0x29.

so need to change with help of VL53L0X available two pins for that is 1)GPIO: use as output interrupts from the sensor, 2) XSHUT: is Active-low ShutDown Input Pin.

As above need to work with interruptions. Is the issue which I try to solve.

SO my query is:

  1. how to set I2C Slave device address.
  2. how to read GPIO interrupts in BBB.
    Or another way to get Multiple VL53L0X (TOF) sensor data.

I use this sensor. :Buy VL53L0X Distance Sensor TOF Sensor Module In India | Robu.in

Hi,

I believe this can help changing the address: https://www.st.com/resource/en/application_note/dm00280486-using-multiple-vl53l0x-in-a-single-design-stmicroelectronics.pdf

or this one:

By my readings, you just can change the address on boot and it’s not permament, on every boot you has to change the address again,

Thank you For Answer.

Is all about CPP. But I need it in the c source file.

Thank You.
