How to distinguish VL53L5CX and VL53L7CX after assembly?

[PJDE]

Hi,

is there a way to distinguish both mentioned sensors other than by complex optical measurements (they have different FOVs)? We have built devices with both types of sensors and our firmware calculates x/y/z coordinates from the reported distances and so has to choose the correct pitch matrix.

Thx Peter

Hello Peter,

To differenciate the L5CX from the L7CX devices, you can add the three following lines in your main file :

  uint8_t fw_flags[8];
    status |= vl53l5cx_dci_read_data(&Dev, fw_flags, 0xE0C4, sizeof(fw_flags));
    printf("Module type = %u (0 for vl53l5cx, 1 for vl53l7cx)\n", fw_flags[1]);
